Fault detection of Pressure Sensor 39877618
Check the faults on the construction site, the vast majority of which are caused by the improper use and installation of pressure sensors, summed up in several aspects.
1. Primary components (orifice plate, remote measuring joint, etc.) are blocked or installed in wrong form, and the pressure point is unreasonable.
2, pressure tube leakage or blockage, liquid filling tube residual gas or gas tube residual liquid, there are deposits in the flange of the transmitter process, the formation of measurement dead zone.
3, transmitter wiring is not correct, the power supply voltage is too high or too low, indicating poor contact between the meter head and the instrument wiring terminal.
4. Installation is not strictly in accordance with the technical requirements, and the installation method and site environment do not meet the technical requirements.
Pressure sensor 39877618 matters needing attention, to avoid transmitter with corrosive and high temperature medium contact to avoid damage it; The position of the pressure guide tube installation is best in the occasion of less temperature fluctuation; When measuring some medium with very high temperature, it is necessary to connect the condenser, because to avoid the temperature of the transmitter at work exceeds a certain limit; Keep the tubes clear; When used in the cold winter, if the transmitter is installed outdoors, we also have to pay attention to take good anti-freezing measures, which is in order not to let the liquid in the pressure mouth cause its volume to expand because of icing, so easy to damage the pressure sensor 39877618. When the user is wiring, he should pass the cable through the waterproof joint or winding pipe and tighten the sealing nut, which can prevent liquid leakage of these things through the cable into the housing of the transmitter
