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 new high temperature model RTC (Reference Temperature Calibrator), which is no exception to the above and even more sophisticated than any existing calibrators. The RTC offers many new fantastic features such as: ■ Patented DLC (Dynamic Load Compensation) system for perfect temperature uniformity in...

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, making it possible to perform top calibration specifications without being affected by the actual load, e.g. many sensors or very big sensors. The RTC-700 adds active triple-zone temperature control. The DLC sensor improves the homogeneity even more, by controlling it 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 and...

Fast Temperature Calibration Wide Temperature Range 700°C Time is money! This is why all the RTC calibrators have an increased heating and cooling speed The RTC-700 can perform calibration over a very wide temperature range starting from 33°C and compared to all other calibrators. With its newly developed heating block, the RTC-700 is able up to 700°C (91 to 1292°F). This makes it possible to perform calibration jobs over a range of 667° C to perform a unique combination of high speed and high accuracy, resulting in savings in both (1232° F) with only one calibrator. production downtime and general...

A special 90° angled external reference sensor has been designed to accommodate the calibration of sensors with a transmitter head, top connector, or similar arrangement. The user can decide The integrated support rod is part of the reduced weight whether to read the built-in reference sensor or the more accurate angled reference sensor from philosophy. It is lightweight and very easy to mount on the large, easy-to-read LCD display of the calibrator. The external sensor and the internal sensor the RTC.

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...

Accuracy with External STS Ref. Sensor (models B and C) Relative to reference standard. Specifications by use of the external JOFRA STS-200 reference sensor. Accuracy with Internal Ref. Sensor (models A, B, and C) Accuracy 33 to 660°C is including calibration uncertainty. Accuracy 660 to 700°C ± 0.29°C exclusive calibration uncertainty. RTC-700 is delivered calibrated in 660 to 700°C with calibration uncertainty ±1.4°C Measured after the stability indicator has been on for 15 minutes. Measuring time is 30 minutes.

Weight of Non-Drilled Insert (approx.) 1060 g /37.3 oz Use of other inserts may reduce the performance of the calibrator. To get the best results out of the calibrator, the insert dimensions, tolerance, and material is critical. We highly advise using JOFRA inserts, as they guarantee trouble free operation. Undrilled Inserts All undrilled inserts include insulation plugs. Predrilled Inserts All predrilled inserts have holes for: 4 mm reference sensor • W" reference sensor • 4 mm hole for DLC sensor. All inserts are supplied with an insulation plug drilled with the necessary holes. * Use the insert...
