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

If the pressure thermocouple sensor in high temperature environment for a long time, and do not take protective measures, its main line, spare parts, sealing ring, and movement is likely to burn out. In order to make the thermocouple sensor can 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 thermocouple sensor direct contact with the pressure when the temperature is very low.

in superhigh temperature measurement occasions to use, can lengthen will guide pipe pressure behind the thermocouple 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 thermocouple in pressure sensor or pressure gauge and take joint add 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 kinds of medium temperature high pressure thermocouple sensor installation ways, there is a difference between this and add isolation diaphragm. Thermocouple sensor or the pressure gauge mounted on isolation diaphragm is diaphragm pressure gauge and pressure diaphragm thermocouple sensor, which is designed for easy blocking easily corrosive medium, make medium pressure on the diaphragm, rather than direct contact with the thermocouple and pressure sensor.

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