Reasons for no output phenomenon of temperature transmitter
1. Check whether the power supply of the temperature transmitter is connected reversely, and whether the positive and negative poles of the power supply are connected correctly.
2. Measure whether the power supply of the transmitter has 24V DC voltage; it must be ensured that the power supply voltage to the transmitter is ≥12V (that is, the voltage of the transmitter power input terminal is ≥12V). If there is no power supply, check whether the circuit is disconnected, whether the detection instrument is selected incorrectly (input impedance should be ≤250Ω) and so on.
3. If the pressure transmitter is with a meter head, you need to check whether the meter head is damaged (you can short-circuit the two wires of the meter head first, if the short circuit is normal, it means the meter head is damaged), if the meter head is damaged, You need to change the header.
4. If there is a problem with the pressure transmitter, you can 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 other instruments in the loop are normal.
5. Whether the power supply is connected to the power input end of the transmitter, connect the power cord to the power connection port.
The reason why the temperature transmitter has no output debugging is the above situations. Of course, in practical applications, there may be many problems that cause the temperature transmitter to not work normally. Before installation and use, it is recommended that you take a serious shot of the fault. Under normal circumstances, if a sensitive component fails, it cannot be repaired by the individual, and the manufacturer should contact the manufacturer to replace the integral component.
