Under the environment of high temperature pressure sensor is how to protect

If a long period of work under the environment of high temperature pressure sensor, and do not take protective measures, its main circuit, parts, sealing ring, and movement is likely to burn out. In order to make the sensor can be normal work for a long time, you need to take corresponding measures.

if the measured medium temperature over 100 ℃, the highest reaches 200 ℃, we need to apply pressure to install the cooling coil after add the radiator, such medium by condensing lap after cooling, again through the radiator cooling direct contact with the pressure sensor when the temperature is very low.

in superhigh temperature measurement occasions to use, can lengthen will guide pipe followed by pressure sensor, also can add capillary after installation of radiator to achieve the effect of the cooling medium.

if the temperature of the measured medium in 70 to 80 ℃, then only need the pressure sensor or pressure gauge and take joint and a radiator, so that the temperature is just right down a little bit, make direct contact with instrument after medium through the radiator cooling.

these are several medium high temperature pressure sensor installation ways, there is a difference between this and add isolation diaphragm. On the pressure sensor or pressure gauge equipped with isolation diaphragm is diaphragm pressure gauge and the diaphragm pressure sensor, which is designed for easy blocking easily corrosive medium, make medium pressure on the diaphragm, rather than direct contact and pressure sensors.

you can see from this, installation is correct or not, is not just about the measure precision of the pressure sensor, also have contact with the service life of the sensor. So, in particular, Such as high temperature) Occasions, more should pay attention to the sensor installation method.
