Differential pressure transmitter is an instrument often used in the automation process, which is widely used in industrial equipment, HVAC, industrial gas, indoor and outdoor environmental monitoring, planting and breeding and other fields. In the process of on-site use of differential pressure transmitters, users often encounter this or that problem, today Xingyi’s technicians will take you to understand how to troubleshoot the differential pressure transmitter in the process of use. Investigative Methods – The investigation method is to investigate the ignition, smoke, odor, power supply change, lightning strike, moisture, misoperation, mismaintenance and other conditions before the fault of the differential pressure transmitter occurs. Observational Method– The observation method refers to the observation of the external damage of the differential pressure transmitter circuit, the leakage of the impulse pipe, the overheating of the circuit, the state of the power supply switch, etc. Detection method – The detection method is divided into four parts for detection: open circuit detection, short circuit detection, replacement detection and partial detection. 1. Circuit break detection, separate the suspected faulty part from other parts, and check whether the fault disappears. disappears, the fault is determined, and the next step can be found. 2. Short circuit detection, in the case of staff and on-site safety, the relevant part of the circuit is directly shorted, such as: the output value of the differential transmitter is small, the impulse pipe can be disconnected, and the differential pressure signal can be directly led to both sides of the differential pressure transmitter from outside the primary pressure valve, and the output of the transmitter is observed to judge the connection of the impulse pipeline plugging and leakage. 3. Replacement detection, replace the suspected faulty part and judge the fault position. For example, if it is suspected that the circuit board of the differential pressure transmitter is faulty, it can be temporarily replaced to determine the cause. 4. Partial detection, the measurement loop is divided into several parts, such as: power supply, signal output, signal transmission, signal detection, and inspection by parts, from simple to complex, from the surface to the inside, to narrow the scope and find out the fault location.
