I need to copy and paste Shandong ship domineering wallpaper, but there is no output for the pressure transmitter used by the flowmeter. How to solve it?

  Recently, Shandong Ship has successfully completed various major tasks. Each of the photos taken can be regarded as wallpapers. Setting the wallpaper is as simple as operating a finger and a mouse. Then for the flowmeter industry, you know that the pressure transmitter used in the flowmeter does not How to solve the output? I am here to teach you.

  Pressure transmitters are used in various fields, and they often encounter many problems in use. For measurement such as output, display, accuracy, etc., there will be failures, so how should we deal with these failures? Next, Xiaobian Take everyone to analyze the fault of the pressure transmitter.

  First, when the pressure transmitter fails, we can analyze it step by step and check the cause step by step:

  1. Check whether the power supply of the pressure transmitter is reversed, 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 is necessary to ensure that the power supply voltage supplied to the transmitter is ≥12V (that is, the voltage at the input terminal of the transmitter power supply is ≥12V). If there is no power supply, check whether the circuit is disconnected, check whether the appearance is selected incorrectly (input impedance should be ≤250Ω) and so on.

  3. If the pressure transmitter has a meter head, you need to check whether the meter head is damaged (you can short-circuit the two lines of the meter head first, if it is normal after the short circuit, it means that the meter head is damaged), if the meter head is damaged, The header needs to be replaced.

  4. If there is a problem with the differential pressure transmitter, you can connect the ammeter in series with the 24V power circuit to check whether the current is normal. If it is normal, it means that the transmitter is normal, and now you should check whether other surfaces in the loop are normal.

  5. Whether the power supply is connected to the power input end of the transmitter, and connect the power cord to the power connection port.

  For the pressure transmitter user, mastering its basic principles and fault judgment ability is the necessary knowledge for an operator, so that the problem can be dealt with in time, and it is also one of the necessary skills for a worker.
