Transverse thermal resistance of the common faults and processing methods

Xiamen branch his face heat resistance is measured object surface temperature and internal temperature of the instrument, transverse thermal resistance is the most commonly used in measuring the temperature of the bearing. Industrial heat resistance as temperature measurement sensor, generally with temperature transmitter, controller and display instrument, such as process control system, used in direct measurement or control - all kinds of production process 200℃- 500 ℃ in the range of liquid, vapour and gas medium and the temperature of the solid surface.

WZCM, WZPM series end heat resistance element is made by special processing wire winding, compared with general axial thermal resistance, it is more correctly and quickly reflect the actual temperature of end face, because often be used, so occasionally appear a few problems, the following

just to know about the transverse thermal resistance of the common faults and processing methods.

for what we call the end face maximum thermal resistance instrument faults were the main reasons for thermal resistance circuit. The solution to this problem is to use a multimeter to check circuit part and eliminated. If the wires are disconnected, the repair or replacement. If you have

thermal resistance circuit itself, to be replaced.

end heat resistance short-circuit can cause transverse thermal resistance meter indicates the minimum value, so when there is face hot resistance meter to the minimum value when we first need to check whether the thermal resistance is short circuit, if is caused by short circuit fault, then processing method is: use all

table to short circuit parts, but if it is short circuit, the end resistance shall repair or replace. If the connection is wire short circuit, is processing or replacement.

common faults is transverse thermal resistance the indicated value is lower than actual temperature or instruction is not stable. Reason: protecting tube with water; Metal dust or dirt on terminal box; Short circuit or ground between thermal resistance wire.

processing methods: clean water protection tube drying process and the wet part; Remove junction box on the metal debris and dust; With a multimeter to check the heat resistance grounding short circuit or part, to eliminate, if the short circuit has to be replaced.
