Ametek- Reference Temperature Calibrators RTC-159 Ultra Cooler (-100°C to +155°C [-148 to 311°F])
The RTC-series features our Ametek Jofra-known active dual zone heating technology. Each heating zone is independently controlled for precision temperature calibration. The homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat dissipation
throughout the entire calibration zone. The upper zone compensates for heat loss from the sensor-under-test and from the open top. This design also eliminates the need for extra insulation of sensors-under-test and makes it possible to calibrate liquid-filled and other mechanical sensors. The RTC family can meet any type of industrial temperature calibration need within the -100 to +700°C (-148 to 1292°F) temperature range.
The RTC-159 is the newest member of the well-known JOFRA RTC family. The RTC-159 can perform calibration over a very wide temperature range starting from -100°C and up to 155°C (-148 to 311°F). It can reach -80°C in 65 minutes! The RTC family can meet any type of industrial temperature calibration need within the -100 to +700°C (-148 to 1292°F) temperature range.
To bring our Ametek documented active dualzone technology to an even higher level, Ametek has developed the patent pending new DLC system.
This newly developed unique feature makes it possible to perform top calibration specifications without being affected by the actual load e.g. many sensors or very big sensors. A new DLC sensor, Dynamic Load Compensation sensor,
has been specially developed for this purpose. The RTC calibrator features the active dual zone temperature control which improves the homogeneity in the Ametek by adjusting the temperature in the top of the Ametek to the same temperature as in the bottom. The dual zone keeps this difference at a minimum.
The new DLC sensor improves the homogeneity even more by controlling the homogeneity not only in the Ametek , but also inside the insert, where the sensors under-test are placed during calibration. The DLC sensor measures the temperature homogeneity in the insert and provides feedback to the active dual-zone system, which now compensates the temperature difference to a minimum inside the insert. In this way, the DLC function makes the homogeneity independent of the different loads of the insert.
Model Number Ordering System
The Ametek Jofra model number system consists of 2 choices of M0dels Numbers, 3 choices of Model Versions, 2 Choices of Main Power, 9 different available Power Cords, 8 types of Inserts, 1 DLC Sensor, 3 STS Reference Sensors, 7 calibration types and 3 Accessory choices. A representative P/N is RTC157B230ASMDLCR2EACT which translates to JOFRA RTC-157 B with 230VAC, EU power cord, set of metric inserts, DLC, STS-200 ref. sensor, full EA temp.calibration certificate, and carrying case with trolley. The total number of available model numbers is then 2x3x2x9x8x1x3x7x3=54432 P/N’s. It borders on impractical to list all of the available models so please contact ATEquip for a price and delivery quotation. Refer to the part numbering system list on the datasheet to construct the exact RTC calibrator of your choice.
