1, when the installation should be the pressure-sensitive parts of the transmitter axial perpendicular to the direction of gravity, transmitters if the installation conditions are limited, you should install fixed after the adjustment transmitter 0 to the standard value.
2, the residual pressure is not released, so the sensor 0 and down. The best way to eliminate this is to remove the sensor and see if the 0-bit is normal and try again if the seal is properly replaced.
3, the pressure transmitter output does not change, and then pressure transmitter output suddenly change, pressure relief transmitter 0 can not go back. The cause of this phenomenon is most likely caused by pressure sensor seals.
4, whether to meet the power supply requirements, power supply and transmitter and load equipment there is no wiring error. If there is no voltage or polarity connection on the terminal terminals of the transmitter, the transmitter can be output without voltage.
5, pressure sensors and transmitters of the shell generally need grounding, signal cable should not be mixed with power cable laying, sensors and transmitters around should avoid strong electromagnetic interference. Sensors and transmitters in the use of transmitters should be in accordance with industry regulations for cycle verification.
6, the user selects the pressure sensor and the transmitter, should fully understand the pressure measurement system working condition, according to the need reasonable choice, causes the system to work in the best condition, and may reduce the project cost.
7, through the isolation plate and the filling fluid in the components to the measurement of the two sides of the diaphragm. The measuring diaphragm and the electrodes on both sides of the insulating sheet form a capacitor.
8, pressure transmitter to check once a week, once a month, mainly to remove the dust in the instrument, the electrical components of the careful inspection, the output of the current value to be constantly proofread, pressure transmitter internal is weak, must be separated from the outside strong electricity.
