Product description

The CNG/LPG differential pressure sensor has no output solution: confirm whether the differential pressure sensor is reversed, the power polarity is connected correctly, measure the power supply of the differential pressure sensor, whether it is 24V DC voltage; If there is no power supply, check whether the loop is disconnected.If it is a sensor with the table head, you can check whether the table head is damaged (you can first short circuit the two wires of the table head, if the short circuit is normal, it is the table head damage);    If the watch head is damaged, replace the watch head and connect the power meter to the 24V power supply loop to check whether the current is normal. If the current is normal, the CNG/LPG differential pressure sensor is normal. At this time, check whether other instruments in the loop are normal and whether the power supply is connected to the power input terminal of the pressure sensor.    The pressure output pressure is too large or too small solution: check whether the power supply of the CNG/LPG pressure difference sensor is normal. If it is too small, check whether there is a large load in the loop. Check whether the actual pressure used exceeds the selected range of the differential pressure sensor, and select a pressure sensor with an appropriate range. Check whether the connection is loose; Connect the cable and tighten it. if the power cable connection is correct, the power cable should be connected to the corresponding terminal post.
