PRESYS TE-350P / TE-650P Dry Block Calibrator
The PRESYS TE-350P / TE-650P Dry Block Calibrators control temperature over an insert in order to calibrate thermocouples, thermoresistances, glass thermometers, thermoswitches etc.
PRESYS TE-350P / TE-650P / Dry Block Calibrators beside providing high accuracy temperature values, also allow the measurement of signals generated by the thermocouples, thermoresistances and thermoswitches, which are being calibrated. This due to an embedded calibrator specific for these types of signals, including 4-20 mA.
The PRESYS TE-350P / TE-650P dry block calibrators generate temperature in the insert in order to calibrate thermocouples, RTDs, glass thermometers, thermo-switches. Besides providing high accuracy temperature values, it also allows the measurement of signals generated by the thermo-element which is being calibrated. This is possible due to an embedded calibrator specific for these types of signal, including 4-20 mA. Thus, they incorporate the functions of dry block, standard thermometer and calibrator for RTD, TC and mA.
- TE-350P calibrator model generates temperatures from ambient to 350°C (662°F).
- TE-650P calibrator model generates temperatures from ambient to 650 ºC (1202 ºF).
They present a wide variety of programming resources, allowing the performance of automatic calibrations of thermocouples, thermoresistances, thermoswitches. In this case, the sensor is placed in the insert and their electrical terminals are connected to the embedded calibrator. The operator defines the calibration points and the number of repetitions, then the process is started and all the sequence is automatically accomplished.
The PRESYS TE-350P / TE-650P also many features:
- Use of internal standard thermometer.
- Accuracy to 0.1 ºC, stability of 0.02 ºC and resolution of 0.01ºC.
- Engineering units configurable to °C and °F.
- RTD input for 2, 3 and 4 wires.
- Inputs for mA, thermocouples and thermo-switches.
- Thermo-element reading scaled to ITS-90 or IPTS-68.
- Internal regulated 24 VDC power supply for 2-wire transmitters.
- The electric signal calibrator is independent from the dry block function.
- Carry out completely automatic calibrations without the use of a computer.
- Internal buzzer beeps when the temperature reaches the desired value.
- Keypad to ease the operation and configuration of the calibrator.
- Graphic liquid crystal display.
- Independent safety circuit for over-temperature protection.
- Insert to choose, strap and test leads included.
- Optional carrying case.
