Gas thermocouple: Thermocouple temperature measuring element (thermocouple) is a commonly used temperature measurement instrument, the direct measurement of the temperature, and the temperature signal into electrical signal through the thermoelectric EMFs, meter (two meters) into the measured medium temperature. Thermocouple, appearance is often due to the very not identical, but their basic structure were roughly the same, usually composed of a hot electrode, insulating sleeve protective pipe and the junction box of the main part, usually and display instruments, recording instruments and supporting the use of electronic regulator.

Feature:

1, simple assembly, convenient replacement;

2, the pressure spring type temperature sensing element, seismic performance;

3, high measuring accuracy;

4, large measuring range (200 to 1300 DEG C, under special circumstances 270 to 2800 DEG C);

5, fast thermal response time;

6, high mechanical strength, good pressure resistance;

7, high temperature can reach 2800 degrees;

8, long service life.

Specifications:

1, the thermal potential

1)Heating characteristics: thermocouple flame temperature at 600-700 degrees C, the thermoelectric potential should be greater than or equal to 15MV

2)The cooling characteristics: thermocouple flame temperature at 600-700 degrees C, heating after 5min 1.5min cut off the gas source, the thermal potential should be less than or equal to 1.5mv.

3)Working temperature: tip temperature not higher than 700 DEG C, the rest is not higher than 125 DEG C.

2, the internal resistance range depends on the type and length, in the corresponding drawings are indicated, the tolerances specified values within 10% of.

3, mechanical properties

1)Wire winding or do not bend radius of less than 10mm, should avoid folding and angular part of friction and instruments and apparatus sharp in the assembly and operation, should avoid bending at the welding position around the small angle.

2)The welding position can withstand at least 150N rally.

3)Product size can be customized according to customer requirements.
