The basic working principle of the drop-in level gauge is the static pressure level measurement, that is, the principle that the measured liquid static pressure is proportional to the height of the liquid. In the liquid medium, the pressure generated at a certain depth is generated by the weight of the medium itself above the measuring point.
When measuring steam or other high-temperature, the transmitter and the pipeline are connected together, and the pressure on the pipeline is used to transmit to the transformer. When the measured medium is water vapor, Inject an appropriate amount of water to prevent the superheated steam from directly contacting the transmitter and damaging the sensor;
After switching on the power supply, if the output of the pressure transmitter is too high and greater than 10VDC or the output is too low and less than 2.0VDC after a given input pressure signal, and the input pressure signal is changed and the zero point and span screws are adjusted, the output will have no response.
In the process of power plant operation, the application of transmitters is very extensive and very common, but sometimes various faults may occur. If the faults cannot be eliminated in time, it will seriously affect the safe and economic operation of the unit. Let's talk about the failure and maintenance of pressure transmitters based on our own practical experience.
