Using RUSKA quartz pressure sensing technology and multiple quartz sensors within a single instrument, the 7050i provides advanced percent-of-reading precision over a wide portion of its measurement range.<\/p>\n<p>The Fluke Calibration RUSKA 7050i provides <strong>0.005 % of reading precision from 25 % to 100 % of full scale<\/strong>. Below 25 % of full scale, precision is specified as 0.005 % of the 25 % threshold value. This percent-of-reading performance gives the 7050i excellent rangeability and enables one instrument to cover a wider pressure workload than a conventional pressure indicator specified exclusively as a percentage of full scale.<\/p>\n<p>Selectable full-scale gauge pressure ranges are available from <strong>5 to 1,500 psi (400 mbar to 100 bar)<\/strong>. Permanent absolute pressure ranges from <strong>15 to 50 psia (1 to 4 bar absolute)<\/strong> are also available.<\/p>\n<p>Optional barometric and vacuum references further extend the capabilities of the 7050i for absolute pressure measurement. A negative gauge pressure option is also available.<\/p>\n<p>Unlike an automatic pressure controller, the RUSKA 7050i is designed for <strong>pressure measurement rather than pressure generation and control<\/strong>. The required test pressure is supplied and adjusted using suitable external equipment. For example, the indicator can be combined with a manual pressure control system such as the Fluke Calibration 3990 or with another suitable pressure generation and control system.<\/p>\n<p>At

pressure laboratories<\/li>\n<\/ul>\n<h2>Advanced Percent-of-Reading Precision<\/h2>\n<p>The key advantage of the <strong>Fluke Calibration RUSKA 7050i<\/strong> is its percent-of-reading precision.<\/p>\n<p>From:<\/p>\n<p><strong>25 % to 100 % of full scale<\/strong><\/p>\n<p>the 7050i provides precision of:<\/p>\n<p><strong>0.005 % of reading<\/strong><\/p>\n<p>Below 25 % of full scale, the precision is:<\/p>\n<p><strong>0.005 % of the 25 % FS threshold value<\/strong><\/p>\n<p>This specification provides significantly better rangeability than a conventional full-scale specification.<\/p>\n<p>For example, a 100 psi RUSKA 7050i provides 0.005 % of reading precision between 25 psi and 100 psi.<\/p>\n<p>Below 25 psi, the precision remains based on 0.005 % of the 25 psi threshold.<\/p>\n<p>This allows one pressure indicator to cover a broad range while maintaining excellent measurement performance.<\/p>\n<h2>Quartz Pressure Sensor Technology<\/h2>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> uses precision quartz pressure sensing technology.<\/p>\n<p>Quartz sensors provide excellent characteristics for pressure metrology, particularly in terms of:<\/p>\n<ul data-spread=\"false\">\n<li>Stability<\/li>\n<li>Repeatability<\/li>\n<li>Resolution<\/li>\n<li>Low hysteresis<\/li>\n<li>Long-term performance<\/li>\n<\/ul>\n<p>The 7050i uses multiple quartz sensor ranges within one instrument to achieve its advanced percent-of-reading specification.<\/p>\n<p>This distinguishes the 7050i from the standard 7050, which is specified primarily as a percentage of full scale.<\/p>\n<p>The combination of several sensor ranges allows the 7050i to maintain high performance over a significantly wider portion of its overall measurement range.<\/p>\n<h2>Pressure Ranges up to 1,500 psi<\/h2>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> is available with selectable full-scale gauge pressure ranges from:<\/p>\n<p><strong>5 psi to 1,500 psi<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>400 mbar to 100 bar<\/strong><\/p>\n<p>This allows the pressure indicator to be configured according to the intended calibration workload.<\/p>\n<p>Available configurations cover applications ranging from relatively low pneumatic pressures to industrial pressure calibration at 100 bar.<\/p>\n<p>The selected full-scale range determines the measurement capability and the lower threshold for the percent-of-reading specification.<\/p>\n<h2>Permanent Absolute Pressure Ranges<\/h2>\n<p>In addition to gauge pressure configurations, permanent absolute versions of the RUSKA 7050i are available.<\/p>\n<p>Permanent absolute ranges extend from:<\/p>\n<p><strong>15 to 50 psia<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>1 to 4 bar absolute<\/strong><\/p>\n<p>These versions directly measure absolute pressure.<\/p>\n<p>A tare function can also be used to provide simulated gauge pressure operation.<\/p>\n<p>Permanent absolute configurations are particularly useful when absolute pressure measurement is the primary application.<\/p>\n<h2>Optional Barometric Reference<\/h2>\n<p>For gauge pressure ranges of 15 psi and higher, the <strong>Fluke Calibration RUSKA 7050i<\/strong> can be equipped with an optional barometric reference.<\/p>\n<p>This option allows the instrument to calculate absolute pressure using the measured gauge pressure together with atmospheric pressure.<\/p>\n<p>The barometric reference provides a convenient method of switching between gauge and absolute pressure measurement without requiring an external vacuum pump.<\/p>\n<p>The specified maximum error of the barometric reference is:<\/p>\n<p><strong>0.002 psi per year<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>0.138 mbar per year<\/strong><\/p>\n<p>This option is particularly useful for laboratories that regularly work with both gauge and absolute pressure instruments.<\/p>\n<h2>Optional Vacuum Reference<\/h2>\n<p>For applications requiring improved absolute pressure performance, the <strong>Fluke Calibration RUSKA 7050i<\/strong> can alternatively be equipped with a vacuum reference option.<\/p>\n<p>An external vacuum pump is connected to the reference port and evacuates the reference side of the pressure measurement system.<\/p>\n<p>An integrated vacuum sensor monitors the reference vacuum and enables automatic zeroing in absolute mode.<\/p>\n<p>The vacuum reference option provides lower additional uncertainty than using a secondary barometric reference.<\/p>\n<p>Fluke specifies a maximum vacuum reference error of:<\/p>\n<p><strong>0.0002 psi per year<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>0.014 mbar per year<\/strong><\/p>\n<p>The vacuum reference option is available for suitable pressure ranges from 5 to 1,500 psi.<\/p>\n<h2>Negative Gauge Pressure<\/h2>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> can also be configured for negative gauge pressure measurement.<\/p>\n<p>This extends its capabilities below atmospheric pressure.<\/p>\n<p>Negative gauge pressure applications include:<\/p>\n<ul data-spread=\"false\">\n<li>Compound pressure gauges<\/li>\n<li>Vacuum transmitters<\/li>\n<li>Low-pressure sensors<\/li>\n<li>Negative pressure indicators<\/li>\n<li>Industrial process instruments<\/li>\n<\/ul>\n<p>For the 7050i, negative gauge precision is specified as <strong>0.005 % of 25 % FS or 0.0005 psi, whichever is greater<\/strong>.<\/p>\n<h2>Excellent Long-Term Stability<\/h2>\n<p>Long-term stability is particularly important for an instrument used as a laboratory pressure reference.<\/p>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> provides a specified stability of:<\/p>\n<p><strong>0.0075 % of reading per year<\/strong><\/p>\n<p>The inherent properties of the quartz pressure sensors contribute to this excellent long-term performance.<\/p>\n<p>Stable measurement characteristics help maintain predictable measurement uncertainty between calibration intervals.<\/p>\n<p>Regular calibration remains essential to ensure metrological traceability.<\/p>\n<h2>Total Measurement Uncertainty<\/h2>\n<p>Fluke also specifies total uncertainty for the RUSKA 7050i.<\/p>\n<p>For pressures from 25 % to 100 % of full scale, total uncertainty is specified as:<\/p>\n<p><strong>0.006 % of reading for 90 days<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>0.009 % of reading for one year<\/strong><\/p>\n<p>These specifications include the relevant contributions defined by the manufacturer, such as precision, stability, temperature effects and calibration standard uncertainty.<\/p>\n<p>This performance makes the 7050i particularly suitable for high-accuracy pressure comparison measurements.<\/p>\n<h2>Pressure Measurement \u2013 Not Pressure Generation<\/h2>\n<p>An important distinction when selecting the <strong>Fluke Calibration RUSKA 7050i<\/strong> is that it is a:<\/p>\n<p><strong>Digital Pressure Indicator<\/strong><\/p>\n<p>The instrument measures pressure with high accuracy but does not automatically generate or control the test pressure.<\/p>\n<p>A complete calibration setup therefore requires suitable external pressure generation and adjustment equipment.<\/p>\n<p>Depending on the application, this can include:<\/p>\n<ul data-spread=\"false\">\n<li>Manual pressure control systems<\/li>\n<li>Pneumatic hand pumps<\/li>\n<li>Precision pressure adjusters<\/li>\n<li>Automatic pressure controllers<\/li>\n<li>Vacuum pumps<\/li>\n<li>Gas pressure supplies<\/li>\n<\/ul>\n<p>This architecture provides considerable flexibility because the 7050i can be combined with the pressure generation system best suited to the application.<\/p>\n<h2>Combination with the Fluke Calibration 3990<\/h2>\n<p>For manual pressure calibration, the <strong>Fluke Calibration RUSKA 7050i<\/strong> can be combined with the Fluke Calibration 3990 Manual Pressure Control Pack.<\/p>\n<p>In this configuration:<\/p>\n<ul data-spread=\"false\">\n<li>The 3990 generates and adjusts the pneumatic test pressure.<\/li>\n<li>The RUSKA 7050i measures the reference pressure.<\/li>\n<li>The device under test is connected to the same pressure circuit.<\/li>\n<\/ul>\n<p>This creates a highly accurate manual pressure comparison system.<\/p>\n<p>The 3990 is available in configurations covering vacuum through positive pneumatic pressure, making it a useful complement to the 7050i.<\/p>\n<h2>Calibration of Pressure Gauges<\/h2>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> is well suited for calibration of mechanical and digital pressure gauges.<\/p>\n<p>The reference indicator and device under test are connected to the same pneumatic pressure system.<\/p>\n<p>An external pressure source generates the required pressure.<\/p>\n<p>Once the pressure has stabilized, the indication of the device under test is compared with the pressure measured by the 7050i.<\/p>\n<p>Several increasing and decreasing pressure points can be generated according to the calibration procedure.<\/p>\n<p>Depending on the procedure, characteristics such as:<\/p>\n<ul data-spread=\"false\">\n<li>Indication deviation<\/li>\n<li>Repeatability<\/li>\n<li>Hysteresis<\/li>\n<li>Zero deviation<\/li>\n<\/ul>\n<p>can be evaluated.<\/p>\n<h2>Calibration of Pressure Transmitters<\/h2>\n<p>Pressure transmitters can also be calibrated using the <strong>Fluke Calibration RUSKA 7050i<\/strong> as the reference pressure instrument.<\/p>\n<p>An external pressure source generates the required pneumatic test pressure.<\/p>\n<p>The 7050i measures the actual pressure while suitable electrical measurement equipment measures the transmitter output.<\/p>\n<p>Typical transmitter signals include:<\/p>\n<ul data-spread=\"false\">\n<li>4\u201320 mA<\/li>\n<li>DC voltage<\/li>\n<li>Digital signals<\/li>\n<\/ul>\n<p>This configuration allows pressure and electrical output to be compared at multiple calibration points.<\/p>\n<h2>Calibration of Pressure Sensors and Transducers<\/h2>\n<p>The high precision and excellent rangeability of the RUSKA 7050i make it suitable for characterization and calibration of pressure sensors and transducers.<\/p>\n<p>Typical applications include:<\/p>\n<ul data-spread=\"false\">\n<li>Industrial pressure sensors<\/li>\n<li>Reference pressure sensors<\/li>\n<li>Pressure transducers<\/li>\n<li>Laboratory instrumentation<\/li>\n<li>Research sensors<\/li>\n<li>Production testing<\/li>\n<\/ul>\n<p>The percent-of-reading specification is particularly beneficial when measurements need to cover a broad portion of the sensor range.<\/p>\n<h2>Automatic Zeroing<\/h2>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> provides automatic zeroing.<\/p>\n<p>This simplifies routine operation and helps ensure reliable pressure measurements.<\/p>\n<p>For configurations using the vacuum reference option, automatic zeroing in absolute mode can also be performed.<\/p>\n<p>Zeroing functions can be initiated from the front panel or through the computer interfaces.<\/p>\n<p>This is particularly useful in automated calibration systems.<\/p>\n<h2>Automatic Head Pressure Correction<\/h2>\n<p>Pressure measurements can be influenced by differences in vertical height between the reference instrument and the device under test.<\/p>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> provides automatic correction for head pressure differences.<\/p>\n<p>This function helps compensate for pressure differences caused by the height of the gas column between the reference level and the device under test.<\/p>\n<p>Head correction is particularly relevant in high-accuracy calibration work where even small pressure differences must be considered.<\/p>\n<h2>Multiple Pressure Units<\/h2>\n<p>The RUSKA 7050i supports more than twelve standard pressure units.<\/p>\n<p>These include:<\/p>\n<ul data-spread=\"false\">\n<li>psi<\/li>\n<li>bar<\/li>\n<li>kPa<\/li>\n<li>inHg<\/li>\n<li>inH\u2082O<\/li>\n<li>kg\/cm\u00b2<\/li>\n<li>mmHg<\/li>\n<li>cmHg<\/li>\n<li>cmH\u2082O<\/li>\n<\/ul>\n<p>Several units are available with different reference temperatures.<\/p>\n<p>In addition, the instrument supports:<\/p>\n<p><strong>two user-defined units<\/strong><\/p>\n<p>This provides flexibility when working with devices that use specialized engineering units.<\/p>\n<h2>Pressure Limits and Alarm<\/h2>\n<p>Upper and lower pressure limits can be configured in the <strong>Fluke Calibration RUSKA 7050i<\/strong>.<\/p>\n<p>If the measured pressure exceeds the defined limit, the instrument can provide an audible warning.<\/p>\n<p>This feature helps protect both the reference indicator and the device under test from unintended overpressure.<\/p>\n<p>It is especially useful when calibrating instruments with pressure ranges below the full-scale capability of the 7050i.<\/p>\n<h2>Large Color Display<\/h2>\n<p>The Fluke Calibration RUSKA 7050i features a:<\/p>\n<p><strong>6.4-inch TFT VGA color display<\/strong><\/p>\n<p>with:<\/p>\n<p><strong>640 \u00d7 480 pixel resolution<\/strong><\/p>\n<p>and up to:<\/p>\n<p><strong>65,000 colors<\/strong><\/p>\n<p>The menu system uses full-text descriptions, simplifying instrument configuration.<\/p>\n<p>Pressure remains visible while navigating many menu functions, helping operators monitor the system continuously.<\/p>\n<h2>High Display Resolution<\/h2>\n<p>Display resolution can be selected up to:<\/p>\n<p><strong>1:1,000,000<\/strong><\/p>\n<p>This enables very small pressure changes to be observed.<\/p>\n<p>High display resolution is especially valuable during pressure stability evaluation and high-accuracy comparison measurements.<\/p>\n<p>Display resolution should not be confused with measurement accuracy, but it provides an important practical advantage for precision pressure work.<\/p>\n<h2>Automated Calibration and Remote Operation<\/h2>\n<p>The <strong>Fluke Calibration RUSKA 7050i<\/strong> provides both:<\/p>\n<p><strong>RS-232<\/strong><\/p>\n<p>and<\/p>\n<p><strong>IEEE-488<\/strong><\/p>\n<p>interfaces.<\/p>\n<p>The Series 7050 uses <strong>SCPI command syntax<\/strong>, simplifying integration into automated calibration systems.<\/p>\n<p>The instrument also supports command emulation for several earlier RUSKA product families, including Series 7250, 7215, Model 7000 and Series 6000 instruments.<\/p>\n<p>This can simplify replacement of older RUSKA pressure standards in existing automated systems.<\/p>\n<p>An optional MET\/CAL driver is also available.<\/p>\n<h2>Technical

RUSKA 7050i<\/strong> is designed for laboratories that require high-accuracy pressure measurement over a broad portion of the instrument&#8217;s range.<\/p>\n<p>Its most important advantage is the <strong>0.005 % of reading precision from 25 % to 100 % of full scale<\/strong>.<\/p>\n<p>Unlike conventional instruments specified only as a percentage of full scale, the percent-of-reading performance allows the 7050i to maintain excellent measurement capability as pressure decreases.<\/p>\n<p>Multiple quartz pressure sensors within the instrument make this advanced rangeability possible.<\/p>\n<p>Selectable pressure ranges from <strong>5 to 1,500 psi (400 mbar to 100 bar)<\/strong> cover a wide variety of pneumatic calibration applications.<\/p>\n<p>Permanent absolute pressure versions and optional barometric, vacuum and negative gauge configurations further expand the measurement capability.<\/p>\n<p>Long-term stability of <strong>0.0075 % of reading per year<\/strong> makes the instrument particularly suitable for use as a laboratory pressure reference.<\/p>\n<p>RS-232 and IEEE-488 interfaces, SCPI commands and compatibility with legacy RUSKA command structures support integration into automated calibration systems.<\/p>\n<p>For manual calibration systems, the 7050i can be combined with a suitable external pressure generation and control system such as the Fluke Calibration 3990.<\/p>\n<p>This separation of pressure measurement from pressure generation gives laboratories considerable flexibility when designing a pressure calibration workstation.<\/p>\n<p>For calibration laboratories, research facilities and pressure instrument manufacturers requiring a stable, high-accuracy pneumatic pressure reference, the Fluke Calibration RUSKA 7050i provides an excellent combination of precision, rangeability and long-term stability.<\/p>\n<p>At <strong>europascal<\/strong>, we can assist you in selecting the appropriate RUSKA 7050i
