Differential pressure transmitter is a common instrument, which has a wide range of applications in environmental protection industry, medical industry, HVAC industry, industrial control, etc. In the actual use process, the operation of some differential pressure transmitters needs our attention. When the environment of the differential pressure transmitter is harsh, the strong electrical signal will produce various electromagnetic interference, and the lightning induction will produce strong surge pulses. In this case, one of the tricky problems encountered in the microcontroller application system is how to reliably transmit small signals over long distances in harsh environments. Considering that the high-frequency noise of the differential voltage transmitter through the transformer is mainly not based on the mutual inductance coupling of the primary and secondary coils, but by the coupling of the primary and secondary parasitic capacitors, the primary and secondary stages of the isolation transformer are isolated by a shielding layer to reduce their distributed capacitance to improve the ability to resist common mode interference. Due to the small measuring range of differential pressure transmitters, the dead weight of the sensing element in the differential pressure transmitter affects the output of the differential pressure transmitter. Therefore, it is normal for the differential pressure transmitter to have a zero change during installation and operation. When installing the differential pressure transmitter, the differential pressure transmitter pressure sensor should be axially perpendicular to the direction of gravity. If the on-site installation conditions of the differential pressure transmitter are restricted, the zero position of the differential pressure transmitter should be adjusted to the standard value after installation. As a manufacturer and sales manufacturer of differential pressure transmitters, our technicians suggest that if you encounter abnormal conditions during on-site use, do not disassemble the differential pressure transmitter without authorization, contact the purchasing manufacturer in time, and have professional technicians to eliminate and solve it for you, so as not to cause damage to the differential pressure transmitter.
