support from europascal<\/li>\n<\/ul>\n<h2>Ideal for Demanding Calibration Applications<\/h2>\n<p>The <strong>AMETEK RTC-157<\/strong> is particularly suitable for calibration applications requiring excellent temperature stability and uniformity.<\/p>\n<p>Typical applications include calibration laboratories, pharmaceutical manufacturing, food processing, industrial maintenance and quality assurance.<\/p>\n<p>The instrument can be used to calibrate Pt100 sensors, Pt1000 sensors, industrial RTDs, thermocouples and precision temperature probes.<\/p>\n<p>Its temperature range also makes it suitable for applications involving refrigeration systems, environmental monitoring and temperature controlled production processes.<\/p>\n<p>The active dual zone heating and cooling system helps minimize temperature gradients within the calibration insert.<\/p>\n<p>This is especially important when calibrating sensors with different diameters, sensing element lengths or immersion characteristics.<\/p>\n<p>For demanding comparison calibrations, the AMETEK RTC-157 can be used with a calibrated external reference thermometer.<\/p>\n<p>The reference thermometer and device under test are inserted into suitable calibration holes and allowed to reach thermal equilibrium.<\/p>\n<p>The temperature indicated by the device under test can then be compared with the reference temperature.<\/p>\n<h2>Temperature Range from \u221245 \u00b0C to +155 \u00b0C<\/h2>\n<p>The AMETEK RTC-157 provides a wide temperature calibration range.<\/p>\n<p>At an ambient temperature of 23 \u00b0C, the specified range is:<\/p>\n<p><strong>\u221245 \u00b0C to +155 \u00b0C<\/strong><\/p>\n<p>The minimum achievable temperature depends on ambient conditions.<\/p>\n<table>\n<tbody>\n<tr>\n<th>Ambient Temperature<\/th>\n<th>Minimum Calibration Temperature<\/th>\n<\/tr>\n<tr>\n<td>0 \u00b0C<\/td>\n<td>\u221257 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>23

\u00b0C<\/li>\n<li>\u221220 \u00b0C<\/li>\n<li>0 \u00b0C<\/li>\n<li>+25 \u00b0C<\/li>\n<li>+50 \u00b0C<\/li>\n<li>+75 \u00b0C<\/li>\n<li>+100 \u00b0C<\/li>\n<li>+125 \u00b0C<\/li>\n<li>+155 \u00b0C<\/li>\n<\/ul>\n<p>The ability to generate temperatures below ambient temperature makes the AMETEK RTC-157 particularly useful for refrigeration and environmental monitoring applications.<\/p>\n<h2>High Temperature Accuracy<\/h2>\n<p>The AMETEK RTC-157 provides excellent temperature accuracy.<\/p>\n<p>The manufacturer specifies two different accuracy values depending on the reference configuration.<\/p>\n<h3>Accuracy with Internal Reference<\/h3>\n<p>When using the internal reference thermometer, the specified accuracy is:<\/p>\n<p><strong>\u00b10.10 \u00b0C<\/strong><\/p>\n<p>This specification applies to the internal temperature indication under defined operating conditions.<\/p>\n<h3>Accuracy with External Reference<\/h3>\n<p>When using the specified external reference thermometer, the accuracy can reach:<\/p>\n<p><strong>\u00b10.04 \u00b0C<\/strong><\/p>\n<p>This specification applies to configurations equipped with an external reference thermometer input.<\/p>\n<p>The external reference sensor measures the temperature within the calibration insert.<\/p>\n<p>This allows more accurate comparison calibrations than relying exclusively on the internal temperature indication.<\/p>\n<p>The manufacturer&#8217;s accuracy specifications must not be confused with the expanded measurement uncertainty of an individual calibration certificate.<\/p>\n<h2>Excellent Temperature Stability of \u00b10.005 \u00b0C<\/h2>\n<p>One of the most important advantages of the AMETEK RTC-157 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 stability specification of only five millikelvin.<\/p>\n<p>Temperature stability describes the variation of the calibration temperature over time under defined operating conditions.<\/p>\n<p>Excellent temperature stability is essential for high accuracy temperature calibration.<\/p>\n<p>Stable temperature conditions reduce measurement fluctuations and improve the repeatability of comparison measurements.<\/p>\n<p>This is particularly important when calibrating precision resistance thermometers and industrial temperature sensors.<\/p>\n<p>The stability specification is evaluated under the manufacturer&#8217;s defined measurement conditions.<\/p>\n<h2>Active Dual Zone Temperature Control<\/h2>\n<p>The AMETEK RTC-157 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 opening of the calibration block and the inserted temperature sensors.<\/p>\n<p>This technology improves temperature homogeneity and reduces axial temperature gradients.<\/p>\n<p>The active dual zone system is particularly useful when calibrating sensors with different dimensions or sensing element positions.<\/p>\n<p>It also improves the calibration conditions for certain mechanical thermometers and liquid filled temperature sensors.<\/p>\n<h2>Dynamic Load Compensation<\/h2>\n<p>The AMETEK RTC-157 supports Dynamic Load Compensation technology in suitable configurations.<\/p>\n<p>Dynamic Load Compensation is designed to compensate for temperature disturbances caused by the sensors inserted into the calibration block.<\/p>\n<p>When large sensors or multiple sensors are inserted, heat conduction through the sensor stems can influence the temperature distribution.<\/p>\n<p>The compensation system helps maintain a uniform temperature within the calibration insert.<\/p>\n<p>This is particularly useful when calibrating several temperature sensors simultaneously.<\/p>\n<p>The function requires the appropriate instrument configuration and compatible DLC equipment.<\/p>\n<p>Dynamic Load Compensation should not be confused with temperature stability or the calibration uncertainty of the reference thermometer.<\/p>\n<h2>Excellent Radial Temperature Homogeneity<\/h2>\n<p>The AMETEK RTC-157 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 for comparison calibrations.<\/p>\n<p>When a reference thermometer and several devices under test are inserted into different holes, good radial homogeneity helps minimize temperature differences between the sensors.<\/p>\n<p>The actual calibration uncertainty also depends on sensor geometry, immersion depth and thermal contact.<\/p>\n<p>For demanding applications, the complete temperature distribution of the calibration setup should be evaluated.<\/p>\n<h2>High Temperature Resolution<\/h2>\n<p>The AMETEK RTC-157 provides selectable temperature resolution.<\/p>\n<p>Available settings include:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature Resolution<\/th>\n<\/tr>\n<tr>\n<td>1 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>0.1 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>0.01 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>0.001 \u00b0C<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The highest resolution allows temperature changes as small as one millikelvin to be displayed.<\/p>\n<p>This is particularly useful for observing temperature stability and monitoring small temperature changes.<\/p>\n<p>Display resolution must not be confused with temperature accuracy or measurement uncertainty.<\/p>\n<h2>Fast Heating Performance<\/h2>\n<p>The AMETEK RTC-157 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>\u221245 \u00b0C to +23 \u00b0C<\/td>\n<td>7 minutes<\/td>\n<\/tr>\n<tr>\n<td>+23 \u00b0C

minutes<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Fast heating reduces waiting times during multi point calibration procedures.<\/p>\n<p>This is particularly useful when several calibration temperatures must be reached consecutively.<\/p>\n<p>Actual heating times depend on ambient conditions, sensor loading and the selected calibration insert.<\/p>\n<h2>Efficient Cooling Performance<\/h2>\n<p>The AMETEK RTC-157 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 \u00b0C to +100 \u00b0C<\/td>\n<td>5 minutes<\/td>\n<\/tr>\n<tr>\n<td>+100 \u00b0C to +23 \u00b0C<\/td>\n<td>10 minutes<\/td>\n<\/tr>\n<tr>\n<td>+23 \u00b0C to 0

ambient temperature to be generated without a separate liquid calibration bath.<\/p>\n<p>This simplifies calibration procedures and reduces preparation time.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The AMETEK RTC-157 uses interchangeable calibration inserts.<\/p>\n<p>These allow different temperature sensors to be accommodated within the calibration block.<\/p>\n<p>The calibration insert can be selected according to the sensor diameter and required calibration arrangement.<\/p>\n<p>The manufacturer specifies an immersion depth of:<\/p>\n<p><strong>160 mm<\/strong><\/p>\n<p>Sufficient immersion depth is important for minimizing heat conduction errors along the sensor stem.<\/p>\n<p>The appropriate insert should provide good thermal contact between the temperature sensor and the calibration block.<\/p>\n<p>Excessive clearance between the sensor and insert can increase temperature differences.<\/p>\n<p>Different insert configurations are available for individual sensors and comparison calibrations involving multiple sensors.<\/p>\n<h2>Intelligent Reference Sensors<\/h2>\n<p>Configurations equipped with an external reference thermometer input support compatible intelligent reference sensors.<\/p>\n<p>These sensors can store individual calibration coefficients in their connectors.<\/p>\n<p>When the reference sensor is connected, the calibrator can 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 external reference thermometer measures the temperature within the calibration insert.<\/p>\n<p>This enables accurate comparison calibration of temperature sensors.<\/p>\n<h2>Available Configurations<\/h2>\n<p>The AMETEK RTC-157 is available in three configurations.<\/p>\n<h3>AMETEK RTC-157A<\/h3>\n<p>The RTC-157A provides temperature generation and control using the internal temperature reference.<\/p>\n<p>It is suitable for applications where external reference thermometers and measurement instruments are already available.<\/p>\n<h3>AMETEK RTC-157B<\/h3>\n<p>The RTC-157B adds an external reference thermometer input and supports compatible Dynamic Load Compensation equipment.<\/p>\n<p>It is suitable for demanding comparison calibrations requiring an external temperature reference.<\/p>\n<h3>AMETEK RTC-157C<\/h3>\n<p>The RTC-157C provides additional measurement functionality for devices under test.<\/p>\n<p>This configuration is particularly useful for calibration procedures requiring integrated measurement and documentation functions.<\/p>\n<p>The exact configuration and included accessories should be checked when ordering.<\/p>\n<h2>Calibration of Pt100 and RTD Sensors<\/h2>\n<p>The AMETEK RTC-157 is suitable for calibrating resistance temperature detectors.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Pt100 calibration<\/li>\n<li>Pt1000 calibration<\/li>\n<li>Industrial RTD calibration<\/li>\n<li>Precision resistance thermometer calibration<\/li>\n<li>Temperature probe verification<\/li>\n<\/ul>\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 temperature indicated by the device under test.<\/p>\n<p>For high accuracy applications, an external reference thermometer is recommended.<\/p>\n<h2>Calibration of Thermocouples<\/h2>\n<p>The AMETEK RTC-157 can also be used for thermocouple calibration.<\/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>USB Communication and Calibration Software<\/h2>\n<p>The AMETEK RTC-157 includes a USB communication interface.<\/p>\n<p>The interface allows communication with compatible calibration software.<\/p>\n<p>This supports computer assisted calibration procedures and remote operation.<\/p>\n<p>Depending on the selected configuration, calibration procedures can be automated and measurement results documented.<\/p>\n<p>Software assisted calibration is particularly useful for repetitive calibration tasks in laboratories and industrial maintenance departments.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Specification<\/th>\n<th>AMETEK
