What are the differences between the four components of the pressure transmitter, the pressure switch, the pressure sensor and the pressure relay?
The pressure sensor is measured and converted to pressure signal, the pressure transmitter includes a pressure sensor and transmitter, pressure switch, pressure to a certain extent open or disconnected, the pressure relay of similar power relay, only one power, one is the pressure to a certain value of work
The pressure transmitter and the pressure sensor output analog signalsThe pressure switch and the pressure relay output the switching signals
The transmitter and the pressure sensor transmit the signals. The pressure switch and the pressure relay control the opening and closing of the machine.
