Common faults and handlings of thermocouple
 

Thermocouple is often used in nozzle and manifold. Meanwhile, we meet some common faults and handlings of thermocouple during use it .
Phenomena :

1 Thermoelectric shown in meter is smaller than actual value of thermoelectric
2 Thermoelectric shown in meter is greater than actual value of thermoelectric
3 Instability output of thermoelectric
4 Big error between thermocouple and thermoelectric

The common faults and handings of thermocouple 1:
Reason: thermoelectric short-circuiting, thermocouple don’t match with the meter,outside interference.
Treatment: find out the reasons ,keep dry or change the insulator ,use a matched facility, get rid of the interference.

The common faults and handings of thermocouple 2:
Reason: thermocouple don’t match with the meter,DC disturb the signal.
Treatment: use a matched facility,get rid of the interferential signal.

The common faults and handings of thermocouple 3:
Reason: poor contact,installation of thermocouple installed loosely.
Treatment: screw up the screw of terminal,tighten up the thermocouple.

The common faults and handings of thermocouple 4:
Reason: thermode is broken,the installation position of thermocouple is not reasonable,heavy accumulation of dirt on surface of protection tube.
Treatment: change the thermode,change the installation position of thermocouple,clear away dirt on the face.

We hope these information about common faults and handings of thermocouple is helpfull for you.Thank you for your attention.
