reference measurement and advanced temperature control makes it suitable for professional calibration laboratories and industrial quality assurance.<\/p>\n<p>Typical applications include the calibration of Pt100 sensors, precision resistance thermometers, thermocouples and temperature transmitters.<\/p>\n<p>The instrument is also particularly useful for calibrating short sanitary temperature sensors.<\/p>\n<p>These sensors are frequently used in pharmaceutical manufacturing, biotechnology and food processing.<\/p>\n<p>Their short insertion lengths and special mechanical designs can make accurate calibration difficult.<\/p>\n<p>The AMETEK RTC-156 addresses these challenges through active dual-zone temperature control and specially designed calibration inserts.<\/p>\n<p>For demanding applications, an external reference thermometer can be positioned close to the sensing element of the device under test.<\/p>\n<p>This helps reduce errors caused by axial temperature gradients and heat conduction.<\/p>\n<h2>Temperature Range from \u221230 \u00b0C to +155 \u00b0C<\/h2>\n<p>The <strong>AMETEK RTC-156<\/strong> provides a temperature calibration range of:<\/p>\n<p><strong>\u221230 \u00b0C to +155 \u00b0C<\/strong><\/p>\n<p>This specification applies at an ambient temperature of 23 \u00b0C.<\/p>\n<p>The minimum achievable temperature depends on the surrounding temperature.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Ambient Temperature<\/th>\n<th>Calibration Temperature Range<\/th>\n<\/tr>\n<tr>\n<td>0 \u00b0C<\/td>\n<td>\u221246 \u00b0C to +155

\u00b0C<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>This wide operating range makes the instrument suitable for calibration applications both below and above ambient temperature.<\/p>\n<p>Typical calibration temperatures include \u221230 \u00b0C, \u221220 \u00b0C, 0 \u00b0C, 25 \u00b0C, 50 \u00b0C, 100 \u00b0C and 155 \u00b0C.<\/p>\n<p>The AMETEK RTC-156 is especially useful for temperature sensors used in refrigeration, environmental monitoring, pharmaceutical manufacturing and industrial process control.<\/p>\n<h2>High Temperature Accuracy<\/h2>\n<p>The AMETEK RTC-156 provides different accuracy specifications depending on the reference measurement configuration.<\/p>\n<h3>Accuracy with Internal Reference<\/h3>\n<p>When using the internal temperature reference, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.10 \u00b0C<\/strong><\/p>\n<p>This specification describes the temperature accuracy under the manufacturer&#8217;s defined operating conditions.<\/p>\n<h3>Accuracy with External Reference<\/h3>\n<p>When using the specified external STS reference sensor, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.04 \u00b0C<\/strong><\/p>\n<p>This specification applies to the RTC-156B and RTC-156C configurations.<\/p>\n<p>The external reference thermometer measures the temperature directly within the calibration insert.<\/p>\n<p>This allows more accurate comparison measurements than relying exclusively on the internal temperature indication.<\/p>\n<p>The manufacturer&#8217;s accuracy specification must not be confused with the expanded measurement uncertainty of an individual calibration certificate.<\/p>\n<h2>Exceptional Temperature Stability of \u00b10.005 \u00b0C<\/h2>\n<p>One of the most important features of the AMETEK RTC-156 is its excellent temperature stability.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.005 \u00b0C<\/strong><\/p>\n<p>This corresponds to a temperature stability of just five millikelvin.<\/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 stability is particularly important when calibrating precision resistance thermometers and other demanding temperature sensors.<\/p>\n<p>It helps reduce measurement variations during comparison calibration.<\/p>\n<h2>Active Dual-Zone Temperature Control<\/h2>\n<p>The AMETEK RTC-156 features active dual-zone temperature control.<\/p>\n<p>The calibration block contains two independently controlled temperature zones.<\/p>\n<p>The lower zone provides precise temperature control in the main 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 uniformity and reduces axial temperature gradients.<\/p>\n<p>It is particularly useful when calibrating sensors with different immersion depths or mechanical designs.<\/p>\n<p>Active dual-zone control also improves the calibration conditions for short temperature sensors.<\/p>\n<h2>Dynamic Load Compensation<\/h2>\n<p>The AMETEK RTC-156 supports Dynamic Load Compensation, commonly referred to as DLC.<\/p>\n<p>This technology is available with the RTC-156B and RTC-156C configurations when the appropriate DLC sensor is installed.<\/p>\n<p>The DLC system uses a special differential temperature sensor positioned inside the calibration insert.<\/p>\n<p>The sensor measures temperature differences within the insert.<\/p>\n<p>The calibrator uses this information to adjust the active dual-zone temperature control.<\/p>\n<p>This helps compensate for temperature gradients caused by the inserted sensors.<\/p>\n<p>The technology is particularly useful when several temperature sensors are calibrated simultaneously.<\/p>\n<p>It also improves calibration conditions when sensors with large diameters or high thermal conductivity are used.<\/p>\n<p>Dynamic Load Compensation helps reduce the influence of sensor loading on temperature uniformity.<\/p>\n<h2>Excellent Radial Temperature Homogeneity<\/h2>\n<p>The AMETEK RTC-156 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 corresponds to 10 millikelvin.<\/p>\n<p>Good radial temperature homogeneity is particularly important when a reference thermometer and several devices under test are inserted into the calibration block.<\/p>\n<p>It helps ensure that the sensors experience nearly identical temperatures.<\/p>\n<p>The actual temperature differences depend on the calibration insert, sensor dimensions and operating conditions.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The AMETEK RTC-156 uses interchangeable calibration inserts.<\/p>\n<p>These inserts allow temperature sensors with different diameters to be accommodated within the calibration block.<\/p>\n<p>Different insert configurations are available for metric and imperial sensor dimensions.<\/p>\n<p>The manufacturer offers inserts for common sensor diameters, including 3 mm, 4 mm, 6 mm, 8 mm, 10 mm and 12 mm.<\/p>\n<p>Special inserts are also available for short sanitary temperature sensors.<\/p>\n<p>The appropriate insert should be selected according to the sensor diameter and the required calibration procedure.<\/p>\n<p>Good thermal contact between the sensor and insert helps reduce temperature differences.<\/p>\n<p>The manufacturer specifies an immersion depth of:<\/p>\n<p><strong>160 mm<\/strong><\/p>\n<p>Sufficient immersion depth is essential for minimizing heat conduction errors along the sensor stem.<\/p>\n<h2>Calibration of Short Sanitary Temperature Sensors<\/h2>\n<p>The AMETEK RTC-156 is particularly suitable for calibrating short sanitary temperature sensors.<\/p>\n<p>These sensors are commonly used in pharmaceutical manufacturing, biotechnology and food processing.<\/p>\n<p>Sanitary temperature sensors often feature short sensing elements and large process connection flanges.<\/p>\n<p>These characteristics can cause significant heat conduction effects during calibration.<\/p>\n<p>Conventional dry block calibrators may not provide sufficiently uniform temperatures for such sensors.<\/p>\n<p>The AMETEK RTC-156 uses active dual-zone temperature control to compensate for heat losses.<\/p>\n<p>Special calibration inserts and reference sensors are available for these applications.<\/p>\n<p>The reference thermometer can be positioned close to the sensing element of the device under test.<\/p>\n<p>This helps improve temperature comparison measurements and reduce calibration errors.<\/p>\n<h2>Fast Heating Performance<\/h2>\n<p>The AMETEK RTC-156 provides efficient heating performance.<\/p>\n<p>Typical heating times include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature Change<\/th>\n<th>Heating Time<\/th>\n<\/tr>\n<tr>\n<td>\u221230 \u00b0C to +23 \u00b0C<\/td>\n<td>4 minutes<\/td>\n<\/tr>\n<tr>\n<td>+23 \u00b0C

calibration procedures.<\/p>\n<p>The actual heating time depends on ambient conditions, sensor loading and the selected calibration insert.<\/p>\n<h2>Efficient Cooling Performance<\/h2>\n<p>The AMETEK RTC-156 also provides efficient cooling performance.<\/p>\n<p>Typical cooling times include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature Change<\/th>\n<th>Cooling Time<\/th>\n<\/tr>\n<tr>\n<td>+155

calibration procedures involving increasing and decreasing temperature sequences.<\/p>\n<p>The final approach to the lowest temperature requires additional time.<\/p>\n<h2>Intelligent External Reference Sensors<\/h2>\n<p>The RTC-156B and RTC-156C support intelligent external reference temperature sensors.<\/p>\n<p>Compatible STS reference sensors contain individual calibration coefficients stored in their connectors.<\/p>\n<p>When a compatible reference sensor is connected, the calibrator can automatically recognize the stored calibration information.<\/p>\n<p>This simplifies reference thermometer setup.<\/p>\n<p>It also reduces the risk of incorrect calibration coefficient entry.<\/p>\n<p>The external reference thermometer allows accurate temperature comparison measurements.<\/p>\n<p>This is particularly useful for calibration laboratories requiring low measurement uncertainty.<\/p>\n<h2>True Ohm Measurement Technology<\/h2>\n<p>The RTC-156B and RTC-156C provide an external reference thermometer input using four-wire resistance measurement.<\/p>\n<p>The instrument uses True Ohm measurement technology.<\/p>\n<p>This measurement method helps minimize errors caused by thermoelectric voltages in the measurement circuit.<\/p>\n<p>The manufacturer specifies a reference resistance measurement range of:<\/p>\n<p><strong>400 \u03a9<\/strong><\/p>\n<p>The 12-month accuracy is:<\/p>\n<p><strong>\u00b1(0.0012% of reading + 0.0005% of full scale)<\/strong><\/p>\n<p>This provides accurate resistance measurement conditions for compatible reference thermometers.<\/p>\n<h2>Three Available Configurations<\/h2>\n<p>The AMETEK RTC-156 is available in three configurations.<\/p>\n<h3>AMETEK RTC-156A<\/h3>\n<p>The RTC-156A 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 reference thermometers and measurement instruments are already available.<\/p>\n<h3>AMETEK RTC-156B<\/h3>\n<p>The RTC-156B provides the most comprehensive measurement functionality.<\/p>\n<p>In addition to temperature generation, it includes inputs for:<\/p>\n<ul>\n<li>External reference thermometer<\/li>\n<li>Dynamic Load Compensation sensor<\/li>\n<li>Sensors under test<\/li>\n<\/ul>\n<p>The RTC-156B supports RTD, thermocouple and electrical measurement functions.<\/p>\n<p>It is particularly suitable for automated calibration procedures and temperature transmitter testing.<\/p>\n<h3>AMETEK RTC-156C<\/h3>\n<p>The RTC-156C includes inputs for:<\/p>\n<ul>\n<li>External reference thermometer<\/li>\n<li>Dynamic Load Compensation sensor<\/li>\n<\/ul>\n<p>This configuration is suitable for high-accuracy comparison calibrations using external measurement instruments.<\/p>\n<p>Unlike the RTC-156B, the RTC-156C does not provide the complete integrated sensor-under-test measurement functionality.<\/p>\n<h2>USB Communication and Calibration Software<\/h2>\n<p>The AMETEK RTC-156 includes a USB communication interface.<\/p>\n<p>This allows the instrument to communicate with compatible calibration software.<\/p>\n<p>Computer-assisted calibration can simplify repetitive measurement procedures.<\/p>\n<p>Depending on the instrument configuration, calibration software can be used to control temperature setpoints and support documentation.<\/p>\n<p>Automated temperature stepping helps reduce manual intervention.<\/p>\n<p>This is particularly useful in calibration laboratories and industrial quality assurance.<\/p>\n<h2>Calibration of Pt100 and RTD Sensors<\/h2>\n<p>The AMETEK RTC-156 is suitable for calibrating resistance temperature detectors.<\/p>\n<p>Typical applications include Pt100 and Pt1000 sensors.<\/p>\n<p>The sensor is inserted into a suitable calibration insert.<\/p>\n<p>The calibrator generates a stable temperature that can be compared with the indication of the device under test.<\/p>\n<p>For high-accuracy applications, a calibrated external reference thermometer is recommended.<\/p>\n<p>The RTC-156B can additionally measure compatible sensors using its integrated measurement functions.<\/p>\n<h2>Calibration of Thermocouples<\/h2>\n<p>The AMETEK RTC-156 can also be used for thermocouple calibration.<\/p>\n<p>Thermocouples are widely used in industrial temperature measurement.<\/p>\n<p>The calibrator provides a controlled 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>Calibration of Temperature Transmitters<\/h2>\n<p>The AMETEK RTC-156 is suitable for checking 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 4\u201320 mA.<\/p>\n<p>The RTC-156B provides integrated measurement functions for compatible temperature transmitters.<\/p>\n<p>The calibration block generates the required temperature.<\/p>\n<p>The transmitter output can then be compared with the expected signal.<\/p>\n<p>This allows the complete temperature measurement chain to be evaluated.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>AMETEK
