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) series, which is 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 in the insert. ■ Unique, intelligent...

Liquid Bath/Large Diameter Insert The RTC-158/250 calibrators are fitted with a 160 mm (6.3") deep well with a diameter of 63.5 mm (2.5"), which are twice the size of any other dry-block. And, they can be used both as dry-block calibrators and as liquid calibration baths with a magnetic stirrer. With these options, it is now possible to calibrate even more temperatures sensors simultaneously and to calibrate both large and odd-shaped sensors—which is not possible with the remaining product range. The RTC-158/250 calibrators can be used without an external reference sensor. But if an STS-200 reference...

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...

It is lightweight and very easy to mount on the SET-Follows-TRUE (models B & C only) RTC. Two fixing holes are integrated in the calibrator where the support rods can be mounted.

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...
