Pressure sensor damaged several reasons

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

1: measuring the steam or other high temperature medium, should use the radiator pipe, the 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, in order to avoid direct impact sensor diaphragm measured medium, so as to damage the 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 will damage the sensor element isolation diaphragm and lead to damage of sensors, sensor for temperature protection as needed, in case of freezing;

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

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

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

will force sensor is installed in the holes or irregular shape of the hole is too small, it is possible to have an impact on the vibration of the sensor membrane 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.
