\u00b0C<\/h2>\n<p>The <strong>AMETEK PTC-350<\/strong> provides a temperature calibration range of:<\/p>\n<p><strong>+33 \u00b0C to +350 \u00b0C<\/strong><\/p>\n<p>This temperature range covers numerous industrial temperature measurement applications.<\/p>\n<p>Typical calibration temperatures include:<\/p>\n<ul>\n<li>50 \u00b0C<\/li>\n<li>100 \u00b0C<\/li>\n<li>150 \u00b0C<\/li>\n<li>200 \u00b0C<\/li>\n<li>250 \u00b0C<\/li>\n<li>300 \u00b0C<\/li>\n<li>350 \u00b0C<\/li>\n<\/ul>\n<p>The temperature range is specified at an ambient temperature of 23 \u00b0C.<\/p>\n<p>The instrument is particularly suitable for calibrating temperature sensors used in industrial production, pharmaceutical manufacturing, food processing, heating systems and process instrumentation.<\/p>\n<p>The calibration temperature can be adjusted directly using the instrument&#8217;s control panel.<\/p>\n<p>For demanding calibration applications, sufficient stabilization time must be allowed before recording measurement results.<\/p>\n<h2>High Temperature Accuracy<\/h2>\n<p>The AMETEK PTC-350 provides two different accuracy specifications.<\/p>\n<h3>Accuracy with Internal Reference<\/h3>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.2 \u00b0C<\/strong><\/p>\n<p>This value describes the temperature accuracy when using the internal reference sensor.<\/p>\n<h3>Accuracy with External Reference<\/h3>\n<p>When using the specified STS-150 external reference sensor, the manufacturer specifies:<\/p>\n<p><strong>\u00b10.08 \u00b0C<\/strong><\/p>\n<p>This specification applies to the PTC-350B and PTC-350C configurations.<\/p>\n<p>The external reference thermometer 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 specified accuracy applies over a 12-month period under the manufacturer&#8217;s defined conditions.<\/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 PTC-350 provides excellent temperature stability.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>\u00b10.02 \u00b0C<\/strong><\/p>\n<p>This specification describes the temperature variation over time under defined operating conditions.<\/p>\n<p>According to the manufacturer, stability is evaluated after the stability indicator has been active for 10 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>Active Dual-Zone Temperature Control<\/h2>\n<p>The AMETEK PTC-350 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 technology improves temperature homogeneity and reduces temperature gradients.<\/p>\n<p>It is particularly useful when calibrating sensors with different dimensions or sensing element positions.<\/p>\n<p>The active dual-zone system also supports calibration of certain mechanical temperature sensors and liquid-filled thermometers.<\/p>\n<h2>Patented Heating Technology<\/h2>\n<p>The AMETEK PTC-350 uses patented heating technology.<\/p>\n<p>This technology enables rapid heating while maintaining excellent temperature stability.<\/p>\n<p>The manufacturer specifies a heating time of:<\/p>\n<p><strong>7 minutes from 33 \u00b0C to 350 \u00b0C<\/strong><\/p>\n<p>This fast heating performance significantly reduces waiting times between calibration points.<\/p>\n<p>The heating system is designed to provide efficient temperature control throughout the operating range.<\/p>\n<p>For technicians performing multiple calibrations every day, fast heating can improve productivity and reduce downtime.<\/p>\n<h2>Efficient Cooling Performance<\/h2>\n<p>The AMETEK PTC-350 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>350 \u00b0C to 100 \u00b0C<\/td>\n<td>19 minutes<\/td>\n<\/tr>\n<tr>\n<td>100 \u00b0C to 50 \u00b0C<\/td>\n<td>12 minutes<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>These cooling times allow technicians to perform calibration procedures involving both increasing and decreasing temperature sequences.<\/p>\n<p>The actual cooling time depends on ambient conditions, sensor loading and the selected calibration insert.<\/p>\n<h2>Short Stabilization Time<\/h2>\n<p>The AMETEK PTC-350 features a typical stabilization time of:<\/p>\n<p><strong>10 minutes<\/strong><\/p>\n<p>This describes the time required for the calibration block to stabilize under the manufacturer&#8217;s specified conditions.<\/p>\n<p>The stabilization time of the device under test must also be considered.<\/p>\n<p>Large sensors or sensors with slow thermal response may require additional time before reliable measurements can be recorded.<\/p>\n<p>For demanding calibration procedures, temperature stabilization should be verified using a suitable reference thermometer.<\/p>\n<h2>Excellent Radial Temperature Homogeneity<\/h2>\n<p>The AMETEK PTC-350 provides excellent radial temperature homogeneity.<\/p>\n<p>The manufacturer specifies a temperature difference between calibration holes of:<\/p>\n<p><strong>0.02 \u00b0C<\/strong><\/p>\n<p>This characteristic is particularly important when calibrating several 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 and thermal contact.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The AMETEK PTC-350 uses interchangeable calibration inserts.<\/p>\n<p>These allow different temperature sensors 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 diameter<\/td>\n<td>25.8 mm<\/td>\n<\/tr>\n<tr>\n<td>Insert length<\/td>\n<td>150 mm<\/td>\n<\/tr>\n<tr>\n<td>Immersion depth<\/td>\n<td>140 mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Different insert configurations are available.<\/p>\n<p>Metric and imperial multi-hole inserts allow temperature sensors with different diameters to be calibrated.<\/p>\n<p>The appropriate insert should be selected according to the dimensions of the temperature sensors being calibrated.<\/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>Intelligent Reference Sensors<\/h2>\n<p>The PTC-350B and PTC-350C support intelligent reference temperature sensors.<\/p>\n<p>The STS-150 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 calibration information.<\/p>\n<p>This simplifies reference thermometer setup and reduces the risk of entering incorrect calibration coefficients.<\/p>\n<p>For the PTC-350, AMETEK offers the STS-150 reference sensor with a 4 mm diameter and a length of 165 mm.<\/p>\n<p>The reference sensor is designed for accurate comparison measurements within the calibration block.<\/p>\n<h2>True-Ohm Measurement Technology<\/h2>\n<p>The PTC-350B and PTC-350C feature an external reference thermometer input using four-wire resistance measurement.<\/p>\n<p>The system uses True-Ohm technology.<\/p>\n<p>This measurement method helps reduce errors caused by thermoelectric voltages in the measurement circuit.<\/p>\n<p>The reference thermometer input is designed for accurate resistance measurement of compatible platinum resistance thermometers.<\/p>\n<p>This provides reliable measurement conditions for demanding temperature calibration applications.<\/p>\n<h2>Three Available Configurations<\/h2>\n<p>The AMETEK PTC-350 is available in three configurations.<\/p>\n<h3>AMETEK PTC-350A<\/h3>\n<p>The PTC-350A is the basic professional 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

measurements using an external reference sensor.<\/p>\n<p>Unlike the PTC-350B, the PTC-350C does not provide the complete sensor-under-test measurement functionality.<\/p>\n<h2>Automatic Temperature Stepping<\/h2>\n<p>The AMETEK PTC-350 supports automatic temperature stepping.<\/p>\n<p>The user can define multiple temperature setpoints and holding times.<\/p>\n<p>This allows the calibrator to perform predefined temperature sequences automatically.<\/p>\n<p>Automatic stepping is particularly useful for routine calibration procedures.<\/p>\n<p>It reduces manual intervention and helps improve repeatability.<\/p>\n<h2>Temperature Switch Testing<\/h2>\n<p>The PTC-350B supports temperature switch testing.<\/p>\n<p>The instrument can determine switching points and hysteresis.<\/p>\n<p>This function is useful for checking thermostats and temperature switches used in industrial control systems.<\/p>\n<p>The calibrator changes the temperature while monitoring the electrical switch contact.<\/p>\n<p>The resulting switching temperatures can be documented and evaluated.<\/p>\n<p>This functionality is specific to the PTC-350B configuration.<\/p>\n<h2>Large Color Display<\/h2>\n<p>The AMETEK PTC-350 features a large color display.<\/p>\n<p>The display provides clear information about the calibration process.<\/p>\n<p>Depending on the selected configuration,
