Temperature transmitter has no loss

In the use of temperature transmitters, a variety of fault problems often occur, the most common is no output fault, as long as the user properly debugs it, it can generally be solved. The user can properly learn the temperature transmitter without output debugging, which is beneficial to the user to solve the problem. Next, Xiaobian will give you a detailed introduction to the reasons why the temperature transmitter has no loss.

1. Check if the power supply of the temperature transmitter is reversed, and whether the positive and negative poles of the power supply are connected correctly.

2. Measure the power supply of the transmitter, whether there is 24V DC voltage; the power supply voltage to the transmitter must be ≥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 instrument is selected incorrectly (input impedance should be ≤250Ω), and so on.

3. If the pressure transmitter is equipped with a meter head, it is necessary to check whether the meter head is damaged (you can short-circuit the two wires of the meter head first. If it is normal after short circuit, it means the head is damaged). If the meter head is damaged, Then you need to change the header.

4. If there is a problem with the pressure transmitter, connect the ammeter to the 24V power supply circuit to check if the current is normal. If it is normal, the transmitter is normal. In this case, check if other instruments in the loop are normal.

5. Connect the power supply to the transmitter power input terminal and connect the power cable to the power supply wiring port.

The reason why the temperature transmitter has no output debugging is the above. Of course, in practical applications, there may be many problems that cause the temperature transmitter to not work properly. Before installation and use, it is recommended that you take the fault seriously. In general, if a sensitive component fails, the individual cannot repair it. Contact the manufacturer to replace the entire component.
