T-25N,
T-350P and T-650P Dry Block Calibrator models control temperature over an insert in order
to calibrate thermocouples, thermo resistances, glass thermometers, thermo switches
etc.
Besides providing high accuracy temperature
values, they also allow the measurement of signals generated by
thermocouples, thermoresistance and thermo switches, which are being
calibrated.
This is possible due to an embedded calibrator specific
for these types of signal, including 4-20mA.
They incorporate the
functions of dry block, standard thermometer and calibrator for RTD
and TC sensors, besides mA reading.
They
present a wide variety of programming resources, allowing them to
perform automatic calibrations of thermocouples, thermoresistance and thermo switches. In this case, the sensor is placed in the insert and
its electrical terminals are connected to the embedded calibrator, the
operator defines the calibration points and the number of repetitions,
then the process is started so that all the sequence is automatically
accomplished. Another way of performing automatic documented
calibrations is by means of CS-504 Calibration Software for
PC/Windows, which uses RS-232 serial port to connect PC to the dry
block. With CS-504 it is possible to register sensors and instruments
of the factory, generate work orders, create and print calibration
certificates and reports, that is, it brings all advantages of
computer data management to the calibration environment.
