Install the transmitter is often the problem. What should I do?

A, we usually at the time of installation of transmitter, is the pressure sensitive vertical installed with the direction of gravity, but if the installation condition is limited, so after installed the transmitter back the zero state standards. 2, when the rest of the pressure to reach standard release, resulting in a decline in the zero position of the sensor, then the sensor uninstall down at this moment, observe it zero is normal, if it is the normal state, then change the sealing ring to try again. Third, when the transmitter output voltage has not changed, or change suddenly, cause pressure transducer zero return not to go. It may be due to a sealing ring. Fourth, the transmitter power requirement is not accord with a standard, power supply, transducer and load before connection if there is any mistakes, if there is no pressure transmitter terminals, it is possible to cause the transmitter output voltage signal. Five, pressure sensor and transmitter shell is need grounding, signal cable is not able to mix and power cable laying, the sides of the transmitter and sensor must be away from the interference of high voltage induction, also need to do regular inspection. Six, in choosing a transmitter, need to be familiar with the working state of the pressure measurement system, to choose according to their own needs. Seven, pressure transmitter, need a week on a screen, the dust cleared within the transmitter, the calibration of the output current value, the pressure transmitter in the weak current and high voltage is separated from the outside.
