Supply industrial pressure transmitter - industrial pressure transmitter buy ir temperature sensor
When the pressure transmitter is installed in the field, the pressure and differential pressure transmitters reflect many incorrect process parameters: there is a problem of plugging of the pressure guiding tube, and there is a problem that the throttling device, the condensation tank, and the pressure guiding tube are not installed properly. , there are problems with electromagnetic interference, and maintenance problems, etc.
1. Inspection and test: Check whether the transmitter power supply is reversed, measure the power supply of the transmitter, whether there is 24V DC voltage, if it is with the meter, check whether the meter is damaged, and connect the ammeter into the 24V power circuit. , check whether the current is normal, whether the power is connected to the transmitter power input;
2. Solution: If the polarity of the power supply is correctly connected, the power supply voltage to the transmitter must be ≥12V. If there is no power supply, check whether the circuit is disconnected, whether the instrument is selected incorrectly, and the header is damaged. Head, industrial pressure transmitter manufacturer, if normal, the transmitter is normal, at this time should check whether other instruments in the loop are normal, connect the power cord to the power terminal.
