SENSORS, TEST & CALIBRATION

AMETEK continues to develop new techniques to improve the performance, accuracy, convenience, and functionality of the popular Jofra calibration products. By doing so, we maintain our position as the leading worldwide manufacturers of temperature dry-block calibrators. We are proud to introduce our top model RTC (Reference Temperature Calibrator), which is no exception to the above, and even more sophisticated than any existing calibrators. Features & Models The RTC offers many new fantastic features such as: ■ Patented DLC (Dynamic Load Compensation) system for perfect temperature uniformity...

DLC–Dynamic Load Compensation DLC To bring our well documented active dual-zone technology to an even higher level, we have developed the patented DLC system. This feature makes it possible to perform top calibration specifications without being affected by the actual load, e.g. many sensors or very big sensors. The DLC sensor improves on the RTC calibrator’s already advanced dual-zone technology by controlling the homogeneity in not only the well, but inside the insert where the sensors-under-test are placed during calibration. The DLC sensor measures the temperature homogeneity in the insert...

Fast Temperature Calibration -24° C @ 15 min Wide Temperature Range -45°C Time is money! This is why all the RTC calibrators have an increased heating and cooling speed The RTC Series can perform calibration over a very wide temperature range starting from -45°C compared to all other calibrators. Heating and cooling speeds have been increased by up to 20%. and up to 155°C (-49 to 311°F). This makes it possible to perform calibration jobs over a range of The implication is savings in both production downtime and general calibration costs. 200° C (360° F) with only one calibrator.

The integrated support rod is part of the reduced weight philosophy. It is lightweight and very easy to mount on the RTC. Two fixing holes are integrated in the calibrator where the support rods can be mounted. MVI—Secure Temperature Stability MVI stands for ''Mains power Variance Immunity". Unstable mains power is a major contributor to on-site calibration inaccuracies. Traditional temperature calibrators often become unstable in production environments where large electrical motors, heating elements, and other devices are periodically cycled on or off. The cycling of supply power can cause...

JofraCal Calibration Software JofraCal is a highly versatile calibration software that is supplied together with the RTC calibrators. The software ensures easy calibration of all kinds of temperature sensors, such as RTD's, thermocouples, transmitters, and thermoswithes. Furthermore, it can be used for pressure calibration i.e. pressure gauges and pressure switches. JofraCal integrates with Jofra calibration instruments. As for temperature calibrators, it is the whole range of temperature calibrators. Regarding pressure calibrators, it integrates with the Crystal XP2i and nVision. JofraCal also...
