kg<\/li>\n<\/ul>\n<h2>Temperature Range from \u2212100 \u00b0C to +155 \u00b0C<\/h2>\n<p>The <strong>AMETEK RTC-159<\/strong> provides an exceptionally wide temperature calibration range.<\/p>\n<p><strong>\u2212100 \u00b0C to +155 \u00b0C<\/strong><\/p>\n<p>This temperature range covers demanding applications requiring both ultra-low and elevated temperatures.<\/p>\n<p>Typical calibration temperatures include:<\/p>\n<ul>\n<li>\u2212100 \u00b0C<\/li>\n<li>\u221290 \u00b0C<\/li>\n<li>\u221280 \u00b0C<\/li>\n<li>\u221260 \u00b0C<\/li>\n<li>\u221240 \u00b0C<\/li>\n<li>\u221220 \u00b0C<\/li>\n<li>0 \u00b0C<\/li>\n<li>+25 \u00b0C<\/li>\n<li>+50 \u00b0C<\/li>\n<li>+100 \u00b0C<\/li>\n<li>+155 \u00b0C<\/li>\n<\/ul>\n<p>The full temperature range is specified at ambient temperatures of 0 \u00b0C and 23 \u00b0C.<\/p>\n<p>At an ambient temperature of 40 \u00b0C, the minimum achievable temperature is \u221283 \u00b0C.<\/p>\n<p>The minimum temperature can also be influenced by the number and dimensions of the sensors being calibrated.<\/p>\n<p>This distinction is important when selecting the instrument for demanding ultra-low temperature applications.<\/p>\n<h2>High Temperature Accuracy<\/h2>\n<p>The AMETEK RTC-159 provides two different temperature accuracy specifications.<\/p>\n<h3>Accuracy with Internal Reference<\/h3>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.30 \u00b0C<\/strong><\/p>\n<p>This value describes the accuracy when using the internal temperature reference.<\/p>\n<h3>Accuracy with External Reference<\/h3>\n<p>When using the specified STS-200 external reference sensor, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.06 \u00b0C<\/strong><\/p>\n<p>This specification applies to the RTC-159B and RTC-159C configurations.<\/p>\n<p>The external reference thermometer measures the temperature within the calibration insert.<\/p>\n<p>This enables accurate comparison calibrations using a traceable reference thermometer.<\/p>\n<p>The specified accuracy applies under the manufacturer&#8217;s defined conditions over a 12-month period.<\/p>\n<p>It must not be confused with the expanded measurement uncertainty stated on an individual calibration certificate.<\/p>\n<h2>Excellent Temperature Stability<\/h2>\n<p>The AMETEK RTC-159 provides excellent temperature stability.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.03 \u00b0C<\/strong><\/p>\n<p>Temperature stability describes the variation of the calibration temperature over time under defined operating conditions.<\/p>\n<p>The manufacturer evaluates stability after the stability indicator has been active for 15 minutes, followed by a 30-minute measurement period.<\/p>\n<p>Excellent temperature stability is essential for accurate temperature sensor calibration.<\/p>\n<p>Stable temperature conditions help reduce measurement variations during comparison measurements.<\/p>\n<h2>Free Piston Stirling Cooler Technology<\/h2>\n<p>The AMETEK RTC-159 uses advanced Free Piston Stirling Cooler technology.<\/p>\n<p>This cooling system enables the instrument to generate temperatures down to \u2212100 \u00b0C.<\/p>\n<p>The Stirling cooler operates using a closed thermodynamic cycle and provides efficient cooling performance.<\/p>\n<p>Unlike conventional thermoelectric cooling systems, this technology is particularly suitable for generating very low temperatures.<\/p>\n<p>The integrated cooling system eliminates the need for liquid nitrogen during normal operation.<\/p>\n<p>This simplifies ultra-low temperature calibration procedures and improves portability.<\/p>\n<p>The AMETEK RTC-159 is therefore particularly suitable for pharmaceutical laboratories, biotechnology companies and industrial users requiring reliable calibration below \u221280 \u00b0C.<\/p>\n<h2>Active Dual-Zone Temperature Control<\/h2>\n<p>The AMETEK RTC-159 features active dual-zone temperature control.<\/p>\n<p>The system uses two independently controlled temperature zones.<\/p>\n<p>The lower zone provides precise temperature control in the calibration area.<\/p>\n<p>The upper zone compensates for heat losses caused by the open top of the calibration block and the inserted temperature sensors.<\/p>\n<p>This design improves temperature homogeneity and reduces axial temperature gradients.<\/p>\n<p>It is particularly useful when calibrating sensors with different dimensions or sensing element positions.<\/p>\n<h2>Dynamic Load Compensation<\/h2>\n<p>The RTC-159B and RTC-159C support Dynamic Load Compensation.<\/p>\n<p>This technology is designed to reduce temperature gradients caused by the thermal loading of the calibration insert.<\/p>\n<p>When several sensors are inserted simultaneously, heat conduction along the sensor stems can influence the temperature distribution.<\/p>\n<p>The DLC system uses a dedicated differential temperature sensor to monitor temperature differences within the insert.<\/p>\n<p>The measured information is used by the active dual-zone temperature control system to compensate for these effects.<\/p>\n<p>This improves temperature homogeneity and supports accurate comparison calibration.<\/p>\n<p>Dynamic Load Compensation is particularly useful when calibrating:<\/p>\n<ul>\n<li>Multiple temperature sensors simultaneously<\/li>\n<li>Sensors with large diameters<\/li>\n<li>Sensors with different sensing element positions<\/li>\n<li>Industrial Pt100 probes<\/li>\n<li>Temperature sensors with extended sensing elements<\/li>\n<\/ul>\n<p>The DLC function requires the appropriate sensor and is available with the RTC-159B and RTC-159C configurations.<\/p>\n<h2>Fast Heating Performance<\/h2>\n<p>The

requires additional time.<\/p>\n<p>This should be considered when planning calibration procedures involving extremely low temperatures.<\/p>\n<h2>Excellent Radial Temperature Homogeneity<\/h2>\n<p>The AMETEK RTC-159 provides excellent radial temperature homogeneity.<\/p>\n<p>The manufacturer specifies a temperature difference between calibration holes of:<\/p>\n<p><strong>0.01 \u00b0C<\/strong><\/p>\n<p>This characteristic is particularly important when calibrating multiple temperature sensors simultaneously.<\/p>\n<p>Good radial homogeneity helps minimize temperature differences between the reference thermometer and the devices under test.<\/p>\n<p>The actual measurement uncertainty also depends on sensor geometry, immersion depth, thermal contact and loading conditions.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The AMETEK RTC-159 uses interchangeable calibration inserts.<\/p>\n<p>These allow different temperature sensors to be accommodated within the calibration block.<\/p>\n<p>Metric and imperial multi-hole insert kits are available.<\/p>\n<p>The metric insert kit covers sensor diameters from approximately 3 mm to 13 mm.<\/p>\n<p>The imperial insert kit accommodates common sensor diameters from 1\/8 inch to 1\/2 inch.<\/p>\n<p>The manufacturer specifies the following dimensions:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>Value<\/th>\n<\/tr>\n<tr>\n<td>Calibration well diameter<\/td>\n<td>30 mm<\/td>\n<\/tr>\n<tr>\n<td>Calibration well

calibrated.<\/p>\n<p>Good thermal contact between the sensor and insert helps minimize measurement errors.<\/p>\n<h2>Intelligent External Reference Sensors<\/h2>\n<p>The RTC-159B and RTC-159C support intelligent external reference temperature sensors.<\/p>\n<p>The specified STS-200 reference sensor contains individual calibration coefficients stored in its intelligent connector.<\/p>\n<p>When the sensor is connected, the calibrator can automatically recognize the stored calibration information.<\/p>\n<p>This simplifies reference thermometer setup and reduces the risk of entering incorrect calibration coefficients.<\/p>\n<p>The STS-200 reference sensor features a 90-degree angled design.<\/p>\n<p>This facilitates the calibration of temperature sensors with connection heads, threaded fittings or other mechanical restrictions.<\/p>\n<h2>Three Available Configurations<\/h2>\n<p>The AMETEK RTC-159 is available in three configurations.<\/p>\n<h3>AMETEK RTC-159A<\/h3>\n<p>The RTC-159A is the basic reference temperature calibrator.<\/p>\n<p>It provides precise temperature generation and control using the internal temperature reference.<\/p>\n<p>This configuration is suitable for applications where external measurement instruments are already available.<\/p>\n<h3>AMETEK RTC-159B<\/h3>\n<p>The RTC-159B provides the most comprehensive measurement functionality.<\/p>\n<p>In

calibration functions<\/li>\n<\/ul>\n<p>The RTC-159B is particularly suitable for automated calibration procedures.<\/p>\n<h3>AMETEK RTC-159C<\/h3>\n<p>The RTC-159C includes an external reference thermometer input and a Dynamic Load Compensation sensor input.<\/p>\n<p>It is designed for accurate temperature comparison measurements using an external reference sensor.<\/p>\n<p>Unlike the RTC-159B, the RTC-159C does not provide the complete sensor-under-test measurement functionality.<\/p>\n<h2>Calibration of Pt100 and RTD Sensors<\/h2>\n<p>The AMETEK RTC-159 is particularly suitable for calibrating resistance temperature detectors.<\/p>\n<p>Typical applications include Pt100, Pt1000 and industrial RTD calibration.<\/p>\n<p>The temperature sensor is inserted into a suitable calibration insert.<\/p>\n<p>The calibration block generates a stable temperature that can be compared with the temperature indicated by the device under test.<\/p>\n<p>For demanding applications, an

AMETEK RTC-159 can also be used for thermocouple calibration.<\/p>\n<p>Thermocouples are widely used in industrial and laboratory temperature measurement.<\/p>\n<p>The instrument provides a stable temperature environment for checking thermocouple measurement systems.<\/p>\n<p>The thermocouple is inserted into the calibration block and allowed to stabilize.<\/p>\n<p>Its indicated temperature can then be compared with the reference temperature.<\/p>\n<p>For accurate thermocouple calibration, reference junction compensation and the measurement uncertainty of the readout must be considered.<\/p>\n<h2>Temperature Transmitter Calibration<\/h2>\n<p>The AMETEK RTC-159 is suitable for calibrating temperature transmitters.<\/p>\n<p>Temperature transmitters convert temperature sensor signals into standardized electrical output signals.<\/p>\n<p>A common industrial output range is:<\/p>\n<p><strong>4\u201320 mA<\/strong><\/p>\n<p>The RTC-159B can measure compatible transmitter output signals using its integrated sensor-under-test measurement functionality.<\/p>\n<p>The calibration block generates the required temperature.<\/p>\n<p>The transmitter output can then be compared with the expected signal at the selected temperature.<\/p>\n<p>This allows the complete measurement chain to be evaluated.<\/p>\n<h2>Automatic Temperature Stepping<\/h2>\n<p>The AMETEK RTC-159 supports automatic temperature stepping.<\/p>\n<p>Up to 20 temperature steps can be programmed.<\/p>\n<p>The user can define temperature setpoints and holding times.<\/p>\n<p>This allows the
