Common problems and solutions in the installation and debugging of weight transmitters

The weight transmitter is actually a weighing instrument, but it only converts the weight signal into an industrial signal, it is actually a converter. In the process of installing and debugging the weight transmitter, we often encounter some difficult problems.

1. The transmitter has no output

(1) Check whether the transmitter's power supply is connected reversely. If the power supply polarity is correct, it is fine.

(2) If it is not the power supply of the measuring transmitter, whether there is a 24V DC voltage; it must be ensured that the power supply voltage to the transmitter is ≥12V.

(3) If it is with a meter head, check whether the meter head is damaged. If the meter head is damaged, you need to replace the meter head.

(4) Or string the ammeter into the 24V power circuit to check whether the current is normal; if it is normal, the transmitter is normal. At this time, check whether the other instruments in the circuit are normal.

(5) Whether the power supply is connected to the power input end of the transmitter; connect the power cord to the power supply terminal.

2. Transmitter output ≥20mA

(1) Whether the transmitter power supply is normal. If it is less than 12VDC, check whether there is a large load in the loop.

(2) Whether the actual pressure exceeds the selected range of the weight transmitter, select a weight transmitter with an appropriate range again.

(3) Whether the pressure sensor is damaged, severe overload sometimes damages the isolation diaphragm. Need to be sent back to the manufacturer for repair.

(4) Whether the wiring is loose, connect the wires and tighten them.

(5) Whether the power cord wiring is correct, the power cord should be connected to the corresponding terminal.
