A differential pressure sensor is a sensor used to measure the difference between two pressures, typically used to measure the pressure difference between the front and back of a device or component. It is widely used in medical equipment, HVAC, industrial control and other industries. Differential pressure sensors need to pay attention to some of the following issues during installation and use: Differential pressure sensors shall be installed in the absence of pressurization and no power supply for the installation of equipment, and differential pressure sensors as far as possible to be installed in the temperature gradient changes in small occasions. Differential pressure sensors cannot measure media that are incompatible with the material the sensor is in contact with. When installing the differential pressure sensor, it is recommended that the pressure connections at both ends be horizontal so that the installation position has less influence on the sensor. If the interface size and field interface size does not match, you can make your own adapter connection. Differential pressure sensor can be directly connected to the hose, can be directly connected to the measured site of the high (H), low (L) pressure, without the need to install brackets; high-pressure end of the low-pressure end of the pressure to the atmosphere can be used as a pressure transmitter, on the contrary, the low-pressure end of the high-pressure end of the pressure to the atmosphere can be used as a negative-pressure transmitter, vacuum transmitter. Differential pressure sensor in the pressure measurement process, should be slowly pressurized and depressurized, to avoid instantaneous increase to high pressure or drop to low pressure. Differential pressure sensor if installed in poor site will encounter lightning or overpressure and other dangerous damage, we recommend that the user in the distribution box or power supply and transmitter between lightning and overpressure protection. Differential pressure sensor belongs to the weak power equipment, wiring must be separately laid with strong power cables, should comply with the relevant national wiring standards (GB/T50312-2016) for wiring. Differential pressure sensor to ensure that the power supply voltage meets the transmitter power supply requirements. Ensure that the upper limit of static pressure is within the tolerable range of the transmitter. Differential pressure sensor users please do not disassemble by yourself, not to mention touching the diaphragm, so as not to cause damage to the sensor.
