June 6, 2011 - AMETEK announces the JOFRA PTC Professional Temperature Calibrators, The PTC Series has an active dual heating zone system that provides high temperature uniformity in the insert no matter the number or size of the sensors immersed. The calibrators also offer intelligent sensors for plug ‘n’ play connectivity, an easy-to-read full-color VGA display and a USB connection for improved communications and software downloads.
An optional reference sensor measures the temperature in the calibrator’s insert and provides feedback to an active dual-zone temperature system that compensates for the temperature differences resulting from testing various sensors. This allows the PTC Series calibrator to perform highly accurate temperature calibrations with varying sensor sizes and even with multiple sensors under test.
The PTC Series also includes STS-150 (Superior Temperature Standard) reference sensor that is angled at 90 deg and customized so the top of the sensor is only slightly higher than the top of the calibrator. This unique design makes it possible for the PTC Series to calibrate threaded sensors and sensors with connection heads. The STS-150 sensor contains all individual calibration data regarding the sensor, allowing users to change the reference sensor and be up and running immediately.
AMETEK offers three versions of the PTC Series: the PTC-155 covers a temperature range of -25 to 155C (-22 to 311F), the PTC-350 covers a higher temperature range of 33 to 350C (91 to 662F), while the PTC 660 handles temperatures ranging from 33 to 660C (91 to 1220F). Along with a wide temperature range, PTC calibrators have increased heating and cooling speeds, making them even more versatile and cost effective.
Each version is available in three models: PTC-A professional temperature calibrator, PTC-B professional temperature calibrator with input for a reference sensor and sensor-under-test, and PTC-C professional temperature calibrator with input for reference sensors. All models come with AMETEK JOFRACAL proprietary software package as standard.
PTC Series calibrators are rugged, light weight and available with a highly functional carrying case for improved portability and convenience. A specially designed carrying case makes it possible to store and protect reference sensors, inserts, support rods, wires, manuals, plugs and insert tools. In addition, they are part of a comprehensive line of pressure, temperature, and force-measurement and calibration products marketed by AMETEK under the CHATILLON®, JOFRA, LLOYD, and MANSFIELD & GREEN brand names.
