AMETEK Calibration Instruments has just launched the new JOFRA RTC-156, the market's most advanced dry-block calibrator to date.

The new RTC-156 offers unique features such as a patent pending Dynamic Load Compensation (DLC) system which ensures optimal temperature homogeneity in the insert no matter the number and size of sensors immersed. Also unique intelligent sensors reference to "plug'n'play” connectivity, a readable color VGA monitor and USB connection for improved communication and firmware downloads are some of the new features.

RTC-156 covers a wide temperature range from -30°C up to 155°C. The heating and cooling rate has also been further reduced by up to 20% compared with other calibrators.

RTC-156 uses AMETEK's well-known active dual-zone temperature control technology. Each of the calibrators two heating zones are independently controlled for accurate temperature calibration. Temperature homogeneity in the lower zone is close to a liquid bath, and upper zone compensates for heat loss from the sensors-under-test and from the opening at the top. This eliminates the need for additional insulation of the sensors-under-test and allows you to calibrate multiple sensors simultaneously.

The RTC-156 offers a further improvement on this technology with its new DLC sensor, which measures the temperature in the calibrator’s insert and provides feedback to the active dual-zone system to compensate for the temperature differences resulting from testing various sensors. This allows the RTC-156 to perform highly accurate temperature calibrations without being affected by the size and number of sensors under test.

Along with the new DLC sensor, the RTC-156 includes a newly designed STS-200 (Superior Temperature Standard) reference sensor the STS-200 and DLC sensors have been angled 90oand 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 RTC-156 to calibrate threaded sensors and sensors with connection heads.

The RTC-156 Series’ rugged, lightweight design features new multi-hole insert kits that cover most commonly known sensor sizes and a highly functional carrying case for improved portability and convenience. The specially designed carrying case makes it possible to store and protect the DLC sensor and reference sensors, inserts, support rods, wires, manuals, plugs and insert tools.
