Melt pressure sensor is generally used in high temperature environment, mainly used to measure and control the pressure of molten material under high temperature conditions. The probe part of the melt pressure sensor can resist high temperature, but the temperature of the shell can be below 80℃, so it is necessary to pay attention to fixing the installed sensor shell part in the room temperature environment during installation and use. The isolation between the shell and the high temperature area is beneficial to improve the measurement accuracy and service life of the sensor. Because the melt pressure sensor is used to measure high-temperature media, special attention should be paid to its installation. When installing the melt pressure sensor, it is necessary to ensure that no foreign metal objects or plastics are left in the correct installation holes, and all sensors should be removed from the machine before cleaning the extruder. Only when the polymer is in a hot melting state can the sensor be taken out, and immediately wipe the sensor probe diaphragm with a soft cloth after taking it out. The diaphragm of melt pressure sensor is the most easily damaged part. Please don't drop its protective cap before installation, and pay attention to protect the diaphragm of the sensor. The processing of the mounting hole should be carried out according to the technical requirements of the mounting hole size diagram and size table, so as to avoid the diaphragm scratch caused by the nonstandard mounting hole from affecting the normal work of the sensor. It is very helpful for us to know the installation of melt pressure sensor. Although we contact the melt pressure sensor in different ways, it is necessary to master this skill, so that we can be handy in case we need to install the melt pressure sensor in the future. There is no need to learn by rote.
