PTC Series
1 / 13Pages

■What to expect Unique Temperature Performance The PTC series provides precision temperature calibration of sensors, whatever the type or format. This is accomplished through an innovative active dualzone heating technology where each heating zone is independently controlled for precision temperature calibration. The PTC Series performs calibration over a wide temperature range, making it ideal for many industries and applications. PTC-155: -25 to 155°C PTC-350: 33 to 350°C PTC-425: 33 to 425°C PTC-660: 33 to 660°C Introducing the new PTC-425 We are pleased to announce our latest model, the...

Stability Status Shows information about the user selected stability criteria, the actual stability status, and estimations for when stability can be expected. Reference Temperature- Indicates if the internal or external reference sensor is used, the temperature of that sensor, and whether "Set Follows True" is active. Sensor Under Test _ Displays the type of sensor under test connected as well as its temperature. Informative Color Display and Easy Operation The PTC's full color VGA display is very easy to read. The main temperature indications, like SET, READ, TRUE and SUT (Sensor Under...

Integrated functions The PTC Series is a flexible calibrator with many integrated functions. Calibrations are completed in one of four ways. Work Order Calibration Mode MVI – Mains Power Variance Immunity improves temperature stability Unstable mains power supplies are a major contributor to calibration inaccuracies. Traditional temperature calibrators often become unstable in industrial environments where large electrical motors, heating elements, and other devices are periodically cycled on and off. The cycling of supply power can cause lower quality temperature regulators to perform...

Calibration Software Included Multi-hole Insert Kits The PTC is supplied with our highly recommended calibration software JofraCal. All calibrations can be documented with a certificate, given that the PTC is controlled from a PC. When the calibrator has reached the desired temperature and stabillity it will prompt you to type in the DUT temperature. JofraCal documents all your calibration needs within temperature, pressure and process calibration. Easy to Carry Two special multi-hole insert kits have been developed to comply with calibration of almost any sensor diameter without having to...

VMETEK SENSORS, TEST4 CALIBRATION All input specifications apply to the dry block of the calibrator running at the respective temperature (stable + and additional 20 min. period). Input specifications are not applicable to A models. Input specifications are valid for PTC-155/350/425/660. RTD Reference Input (B & C models only) RTD Sensor Under Test Input (B model only) The PTC can optionally be supplied with input for resistance sensors and curves suc as: Pt10(90)385, Pt50(90)385, Pt200(90)385, Pt500(90)385, Pt50(90)391, M50(90)428, M100(90)428, Pt100 Mill and YSi-400

Inserts JOFRAAI# calibration mm\ Inserts for PTC-155 and PTC-350 are made of aluminum. Inserts for PTC-425 and PTC-660 are made of brass. All specifications on hole sizes refer to the outer diameter of the sensor-under-test. The correct clearance size is applied in all predrilled inserts. Predrilled Inserts-metric (mm) Part Numbers Predrilled Inserts-imperial (in) Part Numbers Undrilled Inserts Part Numbers Probe Dia. Use of other inserts may reduce performance of the calibrator. To get the best results out of the calibrator, the insert dimensions, tolerance and material is critical. We...
