Pressure thermocouple sensor damaged several reasons

Many users think of the thermocouple sensor damage is caused by improper installation, but I don't know in fact there are many reasons can cause pressure thermocouple sensor damage cannot be normal production and work. The next project to introduce other several reasons can lead to damage the thermocouple sensor element.

1: measuring the steam or other high temperature medium, should use the radiator pipe, the thermocouple sensor and the pipe together, and use the line pressure to change, before use, if the valve is closed, is used, should be very careful, slowly open the valve, so as to avoid direct hit thermocouple sensor diaphragm measured medium, so as to damage the thermocouple sensor diaphragm;

2: do not use hard objects to touch diaphragm, result in isolation membrane damage;

3: do not allow the ice measured medium, otherwise it will damage the thermocouple sensor element isolation film, cause the thermocouple sensor is damaged, thermocouple sensor for temperature protection as needed, in case of freezing;

4: when measuring steam or other high temperature medium, its temperature should not exceed thermocouple sensor when using the limit of the temperature, the higher pressure thermocouple sensor using the limit of the temperature must use the cooling device;

5: do not use more than 36 v voltage is added to the thermocouple sensor, thermocouple sensor damage;

we have said above caused by improper installation will be damaged, now to introduce the correct installation method:

will forcibly thermocouple sensor is installed in the holes or irregular shape of the hole is too small, it is possible to cause the vibration of the thermocouple sensor membrane hit and damage, select the appropriate tool processing and mounting holes, is helpful to control the size of the mounting holes, so in the process of installation to avoid damage.
