Homogeneity<\/h2>\n<p>The AMETEK CTC-660 provides good radial temperature homogeneity.<\/p>\n<p>The manufacturer specifies:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Temperature<\/th>\n<th>Radial Homogeneity<\/th>\n<\/tr>\n<tr>\n<td>400 \u00b0C<\/td>\n<td>0.03 \u00b0C<\/td>\n<\/tr>\n<tr>\n<td>660 \u00b0C<\/td>\n<td>0.1 \u00b0C<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Radial temperature homogeneity describes temperature differences between different calibration holes.<\/p>\n<p>Good radial homogeneity is particularly important when calibrating several temperature sensors simultaneously.<\/p>\n<p>It helps reduce temperature differences between the reference thermometer and the device under test.<\/p>\n<p>The actual measurement uncertainty also depends on sensor geometry, immersion depth and thermal contact.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The AMETEK CTC-660 uses interchangeable calibration inserts.<\/p>\n<p>These allow temperature sensors with different diameters to be accommodated within the calibration block.<\/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>26 mm<\/td>\n<\/tr>\n<tr>\n<td>Insert outer

and imperial inserts are available.<\/p>\n<p>Single-hole and multi-hole inserts allow the instrument to be adapted to different sensor geometries.<\/p>\n<p>The appropriate insert should be selected according to the dimensions of the temperature sensor.<\/p>\n<p>Good thermal contact between the sensor and insert helps minimize measurement errors.<\/p>\n<p>Excessive clearance can increase temperature differences between the calibration block and the sensing element.<\/p>\n<h2>Compact Design<\/h2>\n<p>The AMETEK CTC-660 is designed for portable temperature calibration.<\/p>\n<p>The instrument weighs approximately:<\/p>\n<p><strong>6.1 kg<\/strong><\/p>\n<p>Its dimensions are:<\/p>\n<p><strong>248 \u00d7 148 \u00d7 305 mm<\/strong><\/p>\n<p>This makes the calibrator suitable for transportation between laboratories and industrial measurement locations.<\/p>\n<p>The compact construction also requires relatively little space on a laboratory workbench.<\/p>\n<p>A protective carrying case is available as an accessory.<\/p>\n<p>The case can be used to transport the calibrator, inserts, reference sensors and additional accessories.<\/p>\n<h2>Two Available Configurations<\/h2>\n<p>The AMETEK CTC-660 is available in two configurations.<\/p>\n<h3>AMETEK CTC-660A<\/h3>\n<p>The CTC-660A is the basic compact temperature calibrator.<\/p>\n<p>It provides

available.<\/p>\n<h3>AMETEK CTC-660C<\/h3>\n<p>The CTC-660C includes an external reference thermometer input.<\/p>\n<p>This allows the instrument to measure a compatible external reference sensor directly.<\/p>\n<p>The external reference thermometer can be used to improve temperature calibration accuracy.<\/p>\n<p>The CTC-660C is particularly suitable for comparison calibrations requiring better accuracy than the internal reference alone.<\/p>\n<p>Neither configuration provides the comprehensive sensor-under-test measurement functions of the professional PTC-B models.<\/p>\n<h2>Intelligent Reference Sensors<\/h2>\n<p>The AMETEK CTC-660C supports compatible intelligent reference temperature sensors.<\/p>\n<p>These sensors contain calibration information stored in an integrated memory chip.<\/p>\n<p>When connected, the calibrator can recognize the sensor and retrieve its calibration coefficients.<\/p>\n<p>This simplifies setup and reduces the risk of incorrect calibration coefficient entry.<\/p>\n<p>The specified external reference sensor for the CTC-660 is the STS-120-A-966.<\/p>\n<p>The reference thermometer measures the actual temperature within the calibration insert.<\/p>\n<p>This allows the device under test to be compared directly with a traceable temperature reference.<\/p>\n<h2>MVI Technology<\/h2>\n<p>The AMETEK CTC-660 features MVI technology.<\/p>\n<p>MVI stands for:<\/p>\n<p><strong>Mains Voltage Immunity<\/strong><\/p>\n<p>This technology helps maintain stable temperature control when the mains supply voltage varies.<\/p>\n<p>Voltage fluctuations can influence the heating performance of conventional temperature calibrators.<\/p>\n<p>MVI technology reduces the sensitivity of the calibration process to such variations.<\/p>\n<p>This is particularly useful for field calibration applications where the electrical supply may not be as stable as in a laboratory.<\/p>\n<h2>Automatic Temperature Stepping<\/h2>\n<p>The AMETEK CTC-660 supports automatic temperature stepping.<\/p>\n<p>The user can define temperature setpoints and holding times.<\/p>\n<p>The calibrator then performs the programmed temperature sequence automatically.<\/p>\n<p>This is particularly useful for repetitive calibration procedures.<\/p>\n<p>Automatic stepping reduces manual intervention and helps improve efficiency.<\/p>\n<p>The function is especially valuable when several temperature sensors must be checked at predefined calibration points.<\/p>\n<h2>Automatic Temperature Switch Testing<\/h2>\n<p>The AMETEK CTC-660 supports automatic temperature switch testing.<\/p>\n<p>Temperature switches are widely used in industrial control systems.<\/p>\n<p>They activate or deactivate electrical contacts when a defined temperature is reached.<\/p>\n<p>The calibrator can generate controlled temperature changes while monitoring the switch contact.<\/p>\n<p>This allows switching temperatures and hysteresis to be determined.<\/p>\n<p>Automatic switch testing is particularly useful for maintenance and quality assurance applications.<\/p>\n<h2>USB Communication Interface<\/h2>\n<p>The AMETEK CTC-660 includes a USB 2.0 communication interface.<\/p>\n<p>The interface allows communication with compatible calibration software.<\/p>\n<p>The instrument can be integrated into computer-assisted calibration procedures.<\/p>\n<p>This helps improve efficiency when performing repetitive calibration tasks.<\/p>\n<p>USB communication also allows the instrument to be controlled remotely using suitable software.<\/p>\n<h2>Calibration Software<\/h2>\n<p>The AMETEK CTC-660 is compatible with JofraCal calibration software.<\/p>\n<p>The software supports temperature calibration procedures and documentation.<\/p>\n<p>It can be used to assist with calibration of RTDs, thermocouples and temperature switches.<\/p>\n<p>Depending on the selected configuration and external measurement equipment, calibration data can be collected and evaluated.<\/p>\n<p>Computer-assisted calibration helps improve repeatability and documentation.<\/p>\n<h2>Calibration of Pt100 and RTD Sensors<\/h2>\n<p>The AMETEK CTC-660 is particularly 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>Temperature probe verification<\/li>\n<li>Precision temperature measurement<\/li>\n<\/ul>\n<p>The temperature sensor is inserted into a suitable calibration insert.<\/p>\n<p>The calibration block generates a controlled temperature.<\/p>\n<p>The indicated temperature of the device under test can then be compared with the reference temperature.<\/p>\n<p>For demanding applications, the CTC-660C can be used with an external reference thermometer.<\/p>\n<p>The complete measurement uncertainty must be evaluated according to the calibration procedure.<\/p>\n<h2>Calibration of Thermocouples<\/h2>\n<p>The AMETEK CTC-660 can also be used for thermocouple calibration.<\/p>\n<p>Thermocouples are widely used in industrial applications requiring elevated temperatures.<\/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>Calibration of Temperature Switches<\/h2>\n<p>The AMETEK CTC-660 is suitable for checking industrial temperature switches.<\/p>\n<p>Temperature switches are used to monitor and control industrial processes.<\/p>\n<p>They activate or deactivate electrical contacts at defined temperatures.<\/p>\n<p>The CTC-660 can generate controlled temperature changes to determine switching points.<\/p>\n<p>The integrated switch testing function simplifies this procedure.<\/p>\n<p>Switching hysteresis can also be investigated by increasing and decreasing the temperature.<\/p>\n<h2>Technical Highlights<\/h2>\n<p>The AMETEK CTC-660 provides the following key
