Pressure Transmitter

1. Sewage discharge is mainly aimed at differential pressure transmitters, pressure transmitters, float level gauges and other instruments. Since the measurement medium contains dust, oil, tiny particles, etc., which are deposited in the reverse pressure pipe (or deposited in the pressure sensing pipe), it is directly or indirect effects on measurement. The sewage discharge cycle […]

NO. Fault Reason Treatment 1 Output indicator transmitter reading zero Whether the power supply electrode is reversed or not Correct wiring Whether the power supply voltage is 10~45VDC Recovery power supply 24VDC Is the diode in the terminal block damaged Replacement of diodes Electronic circuit board damage Replacement of electronic circuit boards 2 Transmitter not

NO. Fault Reason Treatment 1 No outputs Is the switch of the pressure guide tube not turned on Open pressure guide tube Whether the guide pressure pipeline is blocked Unclogging of pressure-guide tubes Is the power supply voltage too low Adjust the supply voltage to 24V Is there any disconnection in the output circuit of

1. Do not use a voltage higher than 36V on the transmitter, it will easily lead to damage.2. The transmitter should not touch the diaphragm with hard objects, it will damage the diaphragm piece.3. The measured medium can not be frozen, otherwise, the sensor element isolation diaphragm is easily damaged, resulting in damage to the

When the pressure gauge data is abnormal, it should be tested and diagnosed according to the physical state of the measured medium – solid, liquid, gas – in a targeted manner (1) When abnormal fluctuations occur in the pressure control instrument, the changes in the process operation should be confirmed first, because such changes are

Introduction For many years, differential pressure meters were the only devices available for measuring volumetric flow rate in a pipe with reasonable accuracy at a reasonable cost. Nowadays there are many alternatives, but even so, the differential pressure meter family still holds the largest slice of the market. Advantages The popularity of differential pressure meters
