Fluke Calibration RUSKA 7050LP<\/strong> is a precise low pressure indicator designed for demanding measurement and calibration of very low pneumatic pressures. The instrument combines high-performance quartz pressure sensing technology with two measurement ranges in a single instrument, automatic range switching and excellent percent-of-reading performance.<\/p>\n The Fluke Calibration RUSKA 7050LP is specifically configured for low pressure applications where conventional pressure indicators may not provide the required resolution and measurement performance. Typical applications include calibration of low pressure gauges, differential pressure transmitters, pressure sensors and other sensitive pneumatic instruments.<\/p>\n Three dual-range configurations are available. Depending on the selected version, the Fluke Calibration RUSKA 7050LP covers 25\/75 mbar, 50\/150 mbar or 87\/250 mbar<\/strong>, corresponding to 10\/30 inH\u2082O, 20\/60 inH\u2082O or 35\/100 inH\u2082O<\/strong>.<\/p>\n A major advantage is the precision specification of 0.005% of reading from 10% to 100% of the maximum full-scale range<\/strong> according to the current Fluke product specification. Below 10% of the maximum full-scale range, the specification is 0.005% of 10% of maximum full scale.<\/p>\n With selectable display resolution up to 1:1,000,000<\/strong> and resolution down to 0.025 Pa \/ 0.0001 inH\u2082O<\/strong>, the 7050LP provides the sensitivity required for demanding low pressure metrology.<\/p>\n At europascal<\/strong>, the Fluke Calibration RUSKA 7050LP can be integrated into professional low pressure calibration systems with suitable pressure generation, adjustment equipment and accessories. For professional calibration and metrological traceability, visit the europascal Calibration Service<\/a>.<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> provides high-performance low pressure measurement for calibration laboratories, industrial metrology and demanding research applications.<\/p>\n Key benefits include:<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> was developed specifically for measuring very small pneumatic pressures.<\/p>\n Low pressure measurement presents special metrological challenges. Small pressure fluctuations caused by environmental influences, tubing, temperature effects or air movement can become significant compared with the actual pressure being measured.<\/p>\n The 7050LP addresses these requirements with dedicated low pressure sensor technology and high measurement resolution.<\/p>\n This makes it suitable for calibration applications involving fractions of an inch of water column through pressure ranges up to 100 inH\u2082O.<\/p>\n The Fluke Calibration RUSKA 7050LP is available in three different dual-range configurations.<\/p>\n The first configuration provides:<\/p>\n 10\/30 inH\u2082O<\/strong><\/p>\n or:<\/p>\n 25\/75 mbar<\/strong>.<\/p>\n The second configuration provides:<\/p>\n 20\/60 inH\u2082O<\/strong><\/p>\n or:<\/p>\n 50\/150 mbar<\/strong>.<\/p>\n The third configuration provides:<\/p>\n 35\/100 inH\u2082O<\/strong><\/p>\n or:<\/p>\n 87\/250 mbar<\/strong>.<\/p>\n This allows users to select the configuration that best matches their low pressure calibration workload.<\/p>\n An important feature of the Fluke Calibration RUSKA 7050LP<\/strong> is the combination of two pressure ranges within one instrument.<\/p>\n This allows the 7050LP to maintain excellent performance at both lower and higher pressures within the selected configuration.<\/p>\n For example, the 25\/75 mbar configuration incorporates both a 25 mbar and a 75 mbar range.<\/p>\n The instrument automatically selects the appropriate range according to the applied pressure.<\/p>\n Changing between the two installed ranges does not require manual intervention.<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> automatically changes ranges as pressure increases or decreases.<\/p>\n This automatic ranging simplifies calibration procedures and allows the operator to concentrate on the measurement rather than manually selecting sensor ranges.<\/p>\n It is particularly advantageous when multiple calibration points cover a broad portion of the instrument’s operating range.<\/p>\n The high measurement performance of the Fluke Calibration RUSKA 7050LP<\/strong> is one of its most important characteristics.<\/p>\n According to the current Fluke specification, precision from 10% to 100% of the maximum full-scale range is:<\/p>\n 0.005% of reading<\/strong>.<\/p>\n Below 10% of maximum full scale, the specification is:<\/p>\n 0.005% of 10% of maximum full scale<\/strong>.<\/p>\n This percent-of-reading performance makes the instrument particularly suitable for calibration applications where a wide usable measurement range is required.<\/p>\n Low pressure calibration requires the ability to resolve very small changes in pressure.<\/p>\n The Fluke Calibration RUSKA 7050LP offers display resolution selectable up to:<\/p>\n 1:1,000,000<\/strong>.<\/p>\n Depending on the selected range and pressure unit, resolution can be as fine as approximately:<\/p>\n 0.025 Pa<\/strong><\/p>\n or:<\/p>\n 0.0001 inH\u2082O<\/strong>.<\/p>\n This high resolution makes small pressure changes clearly visible and supports precise low pressure adjustment and calibration.<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> uses specialized quartz pressure sensing technology.<\/p>\n Quartz sensors are well suited to precision pressure measurement because of their excellent repeatability and stability.<\/p>\n The sensing technology forms the metrological foundation of the 7050LP and enables the instrument to provide the precision required for demanding low pressure calibration.<\/p>\n The Fluke Calibration RUSKA 7050LP uses a true differential pressure sensor.<\/p>\n This is particularly important in very low pressure measurement because changes in ambient pressure and environmental conditions can have a significant influence on the measurement.<\/p>\n The instrument includes both a test port and a reference connection.<\/p>\n For appropriate applications, the reference port can be connected to the test system to reduce unwanted pressure disturbances.<\/p>\n When measuring very small differential pressures, even air movement within a laboratory can become relevant.<\/p>\n HVAC systems, opening doors or other changes in room airflow can create small pressure disturbances.<\/p>\n Because the Fluke Calibration RUSKA 7050LP<\/strong> uses a true differential sensor and provides a reference port, the measurement arrangement can be configured to minimize these unwanted effects.<\/p>\n This is an important advantage for precision low pressure calibration.<\/p>\n The Fluke Calibration RUSKA 7050LP can also be configured with an optional:<\/p>\n negative gauge pressure mode<\/strong>.<\/p>\n This extends the application range to pressure measurements below the reference pressure.<\/p>\n It can be particularly useful when calibrating devices that operate across both positive and negative differential pressure ranges.<\/p>\n The exact configuration should be selected according to the required measurement range and application.<\/p>\n The specified pressure medium for the Fluke Calibration RUSKA 7050LP<\/strong> is:<\/p>\n nitrogen<\/strong><\/p>\n or:<\/p>\n clean, dry air<\/strong>.<\/p>\n Using clean pneumatic media helps protect the sensitive internal measurement system from contamination.<\/p>\n Contaminated, corrosive or liquid media should not be introduced into the pressure system unless expressly permitted by the applicable manufacturer documentation.<\/p>\n The Fluke Calibration RUSKA 7050LP is particularly well suited for calibration of low pressure gauges.<\/p>\n A suitable external pressure source or manual pressure control system generates the required test pressure.<\/p>\n The 7050LP measures the applied pressure with high precision.<\/p>\n The indication of the device under test can then be compared directly with the reference pressure measured by the 7050LP.<\/p>\n Differential pressure transmitters are widely used for:<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> provides the high resolution and low pressure capability required for calibration of sensitive differential pressure transmitters.<\/p>\n Its dual-range design is especially useful when the transmitter must be tested across multiple calibration points.<\/p>\n Low pressure sensors and transducers can also be calibrated using the Fluke Calibration RUSKA 7050LP.<\/p>\n A controlled pneumatic pressure is applied simultaneously to the 7050LP and the device under test.<\/p>\n The output of the sensor is then compared with the pressure measured by the reference indicator.<\/p>\n This configuration is suitable for characterization, adjustment and calibration of precision pressure sensors.<\/p>\n It is important to distinguish the Fluke Calibration RUSKA 7050LP<\/strong> from an automatic pressure controller.<\/p>\n The 7050LP is primarily a:<\/p>\n precision digital pressure indicator<\/strong>.<\/p>\n It measures pressure but does not automatically generate and control the calibration pressure by itself.<\/p>\n A suitable external pressure source and pressure adjustment system are therefore required.<\/p>\n This modular approach allows the pressure measurement standard and pressure generation system to be selected separately.<\/p>\n Fluke offers compatible manual pressure control equipment that can be combined with the 7050 Series.<\/p>\n A typical low pressure calibration arrangement therefore consists of:<\/p>\n Pressure Source + Fine Pressure Adjustment + Fluke Calibration RUSKA 7050LP + Device Under Test<\/strong><\/p>\n This configuration provides precise manual pressure generation and high-performance reference measurement.<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> should not be confused with the RUSKA 7250LP.<\/p>\n The 7050LP is a:<\/p>\n low pressure indicator<\/strong>.<\/p>\n Its primary function is precision pressure measurement.<\/p>\n The 7250LP combines low pressure measurement with:<\/p>\n automatic pressure control<\/strong>.<\/p>\n For applications where pressure only needs to be measured, the 7050LP provides an effective reference solution.<\/p>\n Where fully automatic generation and regulation of calibration pressures are required, the 7250LP is the appropriate alternative.<\/p>\n The Fluke Calibration RUSKA 7050LP uses a large active-matrix color display.<\/p>\n The display has a resolution of:<\/p>\n 640 \u00d7 480 pixels<\/strong>.<\/p>\n Its size is approximately:<\/p>\n 6.4 inches \/ 162.5 mm<\/strong>.<\/p>\n The graphical interface provides clear presentation of measurement values and supports convenient navigation through instrument settings.<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> can be integrated into computerized calibration and measurement systems.<\/p>\n The instrument provides communication capabilities suitable for remote operation and automated data acquisition.<\/p>\n Firmware updates can also be performed through the RS232 interface.<\/p>\n This makes the instrument suitable for both standalone laboratory operation and computer-controlled calibration workstations.<\/p>\n The RUSKA 7050 Series was designed to simplify integration into existing automated calibration systems.<\/p>\n Software written for selected previous-generation RUSKA instruments can be supported through instrument emulation.<\/p>\n This can reduce the amount of software modification required when replacing older pressure measurement equipment.<\/p>\n The Fluke Calibration RUSKA 7050LP can be incorporated into automated calibration workflows.<\/p>\n A LabVIEW driver is available for the 7050 Series.<\/p>\n This enables integration into custom laboratory measurement and automation applications.<\/p>\n The instrument can therefore serve as the pressure reference within a larger automated calibration system.<\/p>\n Professional pressure calibration requires documented metrological traceability.<\/p>\n Fluke specifies a traceable calibration report for the RUSKA 7050 Series, with accredited calibration options also available depending on configuration and service.<\/p>\n At europascal, the instrument can additionally be incorporated into a professional calibration and quality assurance environment.<\/p>\n For calibration services, visit the europascal Calibration Service<\/a>.<\/p>\n The Fluke Calibration RUSKA 7050LP is designed as a professional laboratory instrument.<\/p>\n Its dimensions are approximately:<\/p>\n 178 \u00d7 419 \u00d7 483 mm<\/strong><\/p>\n or:<\/p>\n 7 \u00d7 16.5 \u00d7 19 inches<\/strong>.<\/p>\n The weight is approximately:<\/p>\n 7.5 kg \/ 16 lb<\/strong>.<\/p>\n This format makes the instrument suitable for benchtop use as well as permanent installation in calibration systems.<\/p>\n Rack-mount kits are available for installing the Fluke Calibration RUSKA 7050LP in:<\/p>\n 19-inch EIA cabinets<\/strong>.<\/p>\n This is particularly useful for permanent calibration workstations, automated test systems and metrology laboratories.<\/p>\n The specified operating temperature range is approximately:<\/p>\n 18 \u00b0C to 36 \u00b0C<\/strong>.<\/p>\n The storage temperature range is:<\/p>\n -20 \u00b0C to +70 \u00b0C<\/strong>.<\/p>\n Specified relative humidity is:<\/p>\n 5% to 95%, non-condensing<\/strong>.<\/p>\n For the highest measurement performance, stable laboratory environmental conditions are recommended.<\/p>\n Precision pressure measurement instruments require thermal stabilization.<\/p>\n The recommended warm-up time for the 7050 Series is approximately:<\/p>\n 2 to 3 hours<\/strong>.<\/p>\n The instrument may also be left switched on continuously.<\/p>\n Adequate warm-up helps ensure that the pressure measurement system reaches stable operating conditions before precision measurements are performed.<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> is suitable for:<\/p>\n The Fluke Calibration RUSKA 7050LP<\/strong> is designed specifically for applications where very small pneumatic pressures must be measured with high precision.<\/p>\n Unlike general-purpose pressure indicators, the 7050LP combines two low pressure ranges in one instrument. Automatic range switching allows the appropriate range to be selected without operator intervention.<\/p>\n Three configurations covering 25\/75 mbar, 50\/150 mbar and 87\/250 mbar<\/strong> make it possible to select the instrument according to the required low pressure workload.<\/p>\n Its precision of 0.005% of reading<\/strong> over a wide portion of the measurement range and selectable resolution up to 1:1,000,000<\/strong> provide excellent conditions for demanding calibration work.<\/p>\n The true differential pressure sensor and separate reference connection are particularly valuable at very low pressures, where environmental pressure disturbances can otherwise have a significant influence on measurement results.<\/p>\n A large color display, computer communication capabilities, LabVIEW support and rack-mount options make the instrument suitable for both standalone measurements and integrated laboratory calibration systems.<\/p>\n At europascal<\/strong>, the Fluke Calibration RUSKA 7050LP can be combined with suitable pressure generation, fine adjustment equipment and accessories to create a complete low pressure calibration workstation.<\/p>\n For professional calibration and metrological traceability, visit the europascal Calibration Service<\/a>.<\/p>\n Further products from Fluke Calibration can be found here.<\/a><\/p>\nYour Benefits at a Glance<\/h2>\n
