Product Description

STA providing thermocouples are manufactured in different combinations of metals. The calibrations are K, N, E.J, T, S, R, B. Each calibration has a different temperature range.

Platinum rhodium thermocouple is usually used together with indicating instrument, recording instrument, computer, and so on.

It directly measures liquid, steam, gas medium and surface of solids that all kinds of productive process temperaturefrom 0~1800°C.

Thermocouples are used in industry for measuring the temperature of gases, liquids or solid surfaces etc., Its 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 temperature.

Characteristics of type b thermocouple:

** Simply assembled and easily changed

** Spring-type temperature sensing element, good seismic performance

** High precision to measure temperature

** Large measuring range (-200°C to 1300°C, special case, -270°C to 2800°C)

**Sensitive thermal response

**High mechanical strength, good pressure resistance

**High temperature resistance up to 2800°C

** Long life time

The structure requirements of the thermal couple of type b thermocouple

In order to ensure the thermocouple stable and reliable work, its structure should follow the items below:

1) The welding of the two electrodes to compose the thermocouple should be firm;

2) The two hot electrodes should be well insulated to prevent short circuits;

3) The connection between the thermocouple compensation wire and the free end should be convenient and reliable;

4) Protection tube should protect the heat electrodes from the harmful media adequately.
