How to wire the pressure transmitter

1. Generally it is a 2-wire instrument, 4-20mA signal, if it is not transmitted remotely, only need to connect 24V voltage +, -, if remote transmission needs to form a loop, such as 24V+ connected to pressure gauge+, pressure gauge-connected to 4-20mA+, 4 ～20mA- 24V- can be connected, there may be terminals in the middle, please look at the circuit diagram. 2 Capacitive or resistive, both are the 4-20mA signal output by the transmitter. Now it is based on 1. Generally it is a 2-wire instrument with 4-20mA signal. If it is not transmitted remotely, it only needs to connect 24V voltage +, -, if If you need remote transmission, you need to form a loop, such as 24V+ connected to pressure gauge+, pressure gauge-connected to 4-20mA+, 4-20mA- connected to 24V-, there may be terminals in the middle, please look at the circuit diagram. 2 Capacitive or resistive, both are 4-20mA signals output by the transmitter, and now they are basically two-wire systems.
