\u00b0C<\/h2>\n<p>The <strong>AMETEK PTC-155<\/strong> covers a temperature range from:<\/p>\n<p><strong>\u221225 \u00b0C to +155 \u00b0C<\/strong><\/p>\n<p>This range is specified at an ambient temperature of approximately 23 \u00b0C.<\/p>\n<p>The wide operating range makes the calibrator suitable for temperature calibration applications below, around and above room temperature.<\/p>\n<p>Typical applications include the calibration of Pt100 resistance thermometers, industrial temperature sensors, temperature transmitters and temperature switches.<\/p>\n<p>The AMETEK PTC-155 is particularly useful in industries where accurate temperature measurement is essential for product quality, process stability and regulatory compliance.<\/p>\n<p>These include pharmaceutical manufacturing, food processing, biotechnology, medical technology and industrial production.<\/p>\n<h2>High Accuracy Temperature Calibration<\/h2>\n<p>The AMETEK PTC-155 provides excellent accuracy for professional temperature calibration.<\/p>\n<p>With the internal reference sensor, the manufacturer specifies:<\/p>\n<p><strong>Accuracy: \u00b10.18 \u00b0C<\/strong><\/p>\n<p>When using a suitable external JOFRA STS reference sensor, the specified accuracy improves to:<\/p>\n<p><strong>Accuracy: \u00b10.06 \u00b0C<\/strong><\/p>\n<p>The external reference sensor measures the temperature directly within the calibration insert.<\/p>\n<p>This helps reduce the influence of temperature differences between the internal control sensor and the actual measuring location.<\/p>\n<p>The external reference sensor is particularly useful when calibrating temperature sensors with demanding accuracy requirements.<\/p>\n<p>The PTC-155 B and PTC-155 C configurations support external reference sensor operation.<\/p>\n<h2>Excellent Temperature Stability<\/h2>\n<p>Temperature stability is one of the most important characteristics of a professional temperature calibrator.<\/p>\n<p>The <strong>AMETEK PTC-155<\/strong> offers a temperature stability of:<\/p>\n<p><strong>\u00b10.01 \u00b0C<\/strong><\/p>\n<p>This specification applies under the defined manufacturer test conditions after the stability indicator has been active for ten minutes.<\/p>\n<p>The stability is evaluated over a measurement period of 30 minutes.<\/p>\n<p>Excellent temperature stability reduces fluctuations during calibration and supports repeatable measurement results.<\/p>\n<p>This is particularly important when calibrating high-accuracy resistance thermometers and reference temperature sensors.<\/p>\n<h2>Active Dual-Zone Temperature Control<\/h2>\n<p>One of the most important advantages of the AMETEK PTC-155 is its active dual-zone temperature control.<\/p>\n<p>Conventional dry-block calibrators can experience temperature gradients caused by heat losses at the top of the calibration insert.<\/p>\n<p>These gradients can become more pronounced when several temperature sensors are inserted into the block.<\/p>\n<p>The AMETEK PTC-155 uses two independently controlled temperature zones.<\/p>\n<p>The lower zone controls the calibration temperature.<\/p>\n<p>The upper zone compensates for heat losses caused by the surrounding environment and the sensors under test.<\/p>\n<p>This design improves axial temperature homogeneity and reduces the influence of sensor loading.<\/p>\n<p>The active dual-zone system is particularly beneficial when calibrating multiple sensors simultaneously.<\/p>\n<h2>Excellent Temperature Homogeneity<\/h2>\n<p>Temperature homogeneity describes how uniformly the temperature is distributed within the calibration insert.<\/p>\n<p>The AMETEK PTC-155 offers excellent radial homogeneity.<\/p>\n<p>The manufacturer specifies:<\/p>\n<p><strong>Radial homogeneity: 0.01 \u00b0C<\/strong><\/p>\n<p>This value describes the temperature difference between measuring holes under the specified test conditions.<\/p>\n<p>Good radial homogeneity is important when several temperature sensors are calibrated simultaneously.<\/p>\n<p>The active dual-zone temperature control also improves axial homogeneity.<\/p>\n<p>This helps ensure that sensors with different immersion depths and sensing-element positions experience comparable calibration conditions.<\/p>\n<h2>Fast Heating and Cooling<\/h2>\n<p>The AMETEK PTC-155 is designed for efficient temperature calibration.<\/p>\n<p>The manufacturer specifies the following typical heating and cooling times:<\/p>\n<p><strong>Heating from \u221225 \u00b0C to 23 \u00b0C: 4 minutes<\/strong><\/p>\n<p><strong>Heating from 23 \u00b0C to 155 \u00b0C: 12 minutes<\/strong><\/p>\n<p><strong>Cooling from 155 \u00b0C to 23 \u00b0C: 10 minutes<\/strong><\/p>\n<p><strong>Cooling from 23 \u00b0C to \u221225 \u00b0C: 15 minutes<\/strong><\/p>\n<p>These short transition times reduce waiting periods during calibration procedures.<\/p>\n<p>This is particularly useful when several calibration points must be measured.<\/p>\n<p>For example, a temperature sensor may be calibrated at 0 \u00b0C, 50 \u00b0C, 100 \u00b0C and 150 \u00b0C using a single calibration instrument.<\/p>\n<h2>Dry-Block Calibration Technology<\/h2>\n<p>The AMETEK PTC-155 uses dry-block temperature calibration technology.<\/p>\n<p>The instrument contains a temperature-controlled metal block with an interchangeable calibration insert.<\/p>\n<p>The temperature sensor under test is inserted into a suitable hole.<\/p>\n<p>The block is heated or cooled to the selected temperature.<\/p>\n<p>After thermal stabilization, the sensor indication can be compared with the reference temperature.<\/p>\n<p>Dry-block technology offers several advantages compared with liquid calibration baths.<\/p>\n<p>There is no calibration liquid to transport, refill or clean.<\/p>\n<p>The instrument can be transported easily and used directly at industrial installations.<\/p>\n<p>The dry calibration environment also reduces the risk of contamination.<\/p>\n<h2>Interchangeable Calibration Inserts<\/h2>\n<p>The AMETEK PTC-155 supports interchangeable calibration inserts.<\/p>\n<p>These inserts are available with individual holes or multiple holes for different sensor diameters.<\/p>\n<p>The manufacturer specifies a well diameter of:<\/p>\n<p><strong>26 mm<\/strong><\/p>\n<p>The insert dimensions are approximately:<\/p>\n<p><strong>25.8 mm diameter \u00d7 150 mm length<\/strong><\/p>\n<p>The immersion depth is approximately:<\/p>\n<p><strong>160 mm<\/strong><\/p>\n<p>Multi-hole inserts allow several temperature sensors to be calibrated simultaneously.<\/p>\n<p>This can significantly improve calibration efficiency when multiple sensors require the same temperature points.<\/p>\n<p>The insert configuration should be selected according to the sensor dimensions, immersion requirements and measurement uncertainty.<\/p>\n<h2>External Reference Sensor Input<\/h2>\n<p>The <strong>AMETEK PTC-155 B<\/strong> and <strong>AMETEK PTC-155 C<\/strong> models include an external reference sensor input.<\/p>\n<p>This allows the calibrator to measure the temperature using a compatible JOFRA STS reference sensor.<\/p>\n<p>Suitable reference sensors include:<\/p>\n<p><strong>JOFRA STS-102-A<\/strong><\/p>\n<p><strong>JOFRA STS-150-A-915<\/strong><\/p>\n<p>The external reference sensor provides an independent measurement of the calibration temperature.<\/p>\n<p>The manufacturer specifies accuracy down to \u00b10.06 \u00b0C when using the appropriate external reference sensor.<\/p>\n<p>The external sensor also enables the Set Follows True function.<\/p>\n<h2>Set Follows True Technology<\/h2>\n<p>The AMETEK PTC-155 supports the Set Follows True function when equipped with an appropriate external reference sensor.<\/p>\n<p>In this operating mode, the external reference sensor measures the actual temperature in the calibration insert.<\/p>\n<p>The calibrator automatically adjusts the block temperature until the external reference sensor reaches the selected setpoint.<\/p>\n<p>This reduces temperature differences between the internal control sensor and the actual calibration location.<\/p>\n<p>The function is particularly useful when the calibration insert contains sensors with different thermal characteristics.<\/p>\n<h2>Intelligent Reference Sensors<\/h2>\n<p>AMETEK JOFRA reference sensors feature intelligent connectors that store sensor-specific calibration coefficients.<\/p>\n<p>When the sensor is connected to a compatible PTC calibrator, the instrument recognizes the sensor and retrieves the stored calibration information.<\/p>\n<p>This plug-and-play concept simplifies the calibration setup.<\/p>\n<p>It also reduces the risk of manually entering incorrect sensor coefficients.<\/p>\n<p>The intelligent reference sensor system is especially useful in laboratories where several reference sensors are used.<\/p>\n<h2>Sensor-Under-Test Input<\/h2>\n<p>The <strong>AMETEK PTC-155 B<\/strong> includes an integrated sensor-under-test input.<\/p>\n<p>This allows the calibrator to measure the electrical output of compatible temperature sensors directly.<\/p>\n<p>Depending on the selected sensor type and configuration, the instrument can be used with resistance thermometers, thermocouples and temperature transmitters.<\/p>\n<p>The integrated input simplifies calibration because an additional electrical measuring instrument may not be required for supported sensor types.<\/p>\n<p>This makes the PTC-155 B particularly suitable for automated calibration procedures.<\/p>\n<h2>Automatic Temperature Stepping<\/h2>\n<p>The AMETEK PTC-155 includes automatic temperature stepping functions.<\/p>\n<p>Users can define a sequence of temperature setpoints.<\/p>\n<p>The calibrator automatically moves through the programmed temperature steps.<\/p>\n<p>This reduces manual operation and helps ensure consistent calibration procedures.<\/p>\n<p>Automatic stepping is particularly useful for repetitive calibration tasks involving several temperature sensors.<\/p>\n<p>The function can also help reduce operator errors during routine calibration.<\/p>\n<h2>Automatic Temperature Switch Testing<\/h2>\n<p>The AMETEK PTC-155 supports automatic temperature switch testing.<\/p>\n<p>Temperature switches are used to monitor temperature limits in industrial processes.<\/p>\n<p>During testing, the calibrator increases or decreases the temperature until the switch changes state.<\/p>\n<p>The corresponding switching temperature can be determined.<\/p>\n<p>The reset temperature can also be measured.<\/p>\n<p>The difference between the switching and reset temperatures is the switching hysteresis.<\/p>\n<p>This function is particularly useful for testing thermostats and industrial temperature switches.<\/p>\n<h2>Intuitive Color Display<\/h2>\n<p>The AMETEK PTC-155 features a large color display.<\/p>\n<p>The display provides information about:<\/p>\n<ul data-spread=\"false\">\n<li>Current block temperature<\/li>\n<li>Selected temperature setpoint<\/li>\n<li>Temperature stability<\/li>\n<li>Heating and cooling status<\/li>\n<li>External reference temperature<\/li>\n<li>Sensor-under-test readings on supported models<\/li>\n<li>Calibration functions<\/li>\n<li>Instrument settings<\/li>\n<\/ul>\n<p>The intuitive interface simplifies daily operation and reduces training requirements.<\/p>\n<h2>JofraCal Calibration Software<\/h2>\n<p>The AMETEK PTC-155 is compatible with <strong>JofraCal calibration software<\/strong>.<\/p>\n<p>JofraCal supports automated calibration procedures and measurement documentation.<\/p>\n<p>The software can be used to control compatible temperature calibrators and organize calibration tasks.<\/p>\n<p>It also supports the documentation of measurement results.<\/p>\n<p>This is particularly useful for calibration laboratories and maintenance departments that require repeatable procedures and structured calibration records.<\/p>\n<h2>USB Communication<\/h2>\n<p>The AMETEK PTC-155 includes a:<\/p>\n<p><strong>USB 2.0 interface<\/strong><\/p>\n<p>The USB connection enables communication between the calibrator and a computer.<\/p>\n<p>This allows the instrument to be integrated into computer-controlled calibration procedures.<\/p>\n<p>USB communication is particularly useful when using JofraCal software.<\/p>\n<h2>Compact and Portable Design<\/h2>\n<p>The AMETEK PTC-155 is designed for professional laboratory and field calibration.<\/p>\n<p>The manufacturer specifies dimensions of approximately:<\/p>\n<p><strong>362 \u00d7 171 \u00d7 363 mm<\/strong><\/p>\n<p>The weight is approximately:<\/p>\n<p><strong>10.3 kg<\/strong><\/p>\n<p>The compact design allows the calibrator to be transported between different calibration locations.<\/p>\n<p>Optional protective carrying cases are available.<\/p>\n<p>These cases can also accommodate calibration inserts, reference sensors and additional accessories.<\/p>\n<h2>Technical Highlights<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>AMETEK PTC-155<\/th>\n<\/tr>\n<tr>\n<td>Product type<\/td>\n<td>Professional Dry-Block
