Thermocouples are used in industry for measuring the temperature of
gases,liquids or solid surfaces etc.,It's usually assembled with
indicators,recorders or computers.
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.
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
- Easy assembly and convenient for replacement;
- Spring thermal element with good shock-proof performance;
- Wide mesuring range (0~1600 degree Celsius);
- High mechanical strength and good pressure-resistant performance
Measuring junction structure & advantages:
1 rapid response
2 no suitable in case with interference
1 It responses more slowly than that of the case-connected type.
2 Long service life
3 Resistance to electric interference
1 rapid response
2 suitable to measure the temperature of gas
3 poor mechanical strength in contact with other measuring
