Mineral insulated thermocouple or RTDS in PT100/PT1000 with high
tempertaure sensor
Description:
1) GME's Thermocouples are used in industry for measuring the
temperature of gases, liquids or solid surfaces etc., Its usually
assembled with indicators, recorders or computers.
2) A thermocouple consists of two dissimilar metals joined together
at one end. When the junction of the two metals be cooled or heated
and a voltage is produced that can be correlated back to the
emperature. The calibrations are K, N, E.J, T, S, R, B. Each
calibration has a different temperature range
3)Thermocouple is composed of temperature sensor and signal
converter, signal converter is installed in the junction box of
temperature sensor, temperature sensor produce resistance or
potential effects made by the temperature affect, via
transformation to create a differential voltage signal. The signal
via the amplifier amplification, then through voltage and current
transformation, output 4-20 mA current signal corresponding to the
range.
