Explosion-proof pressure transmitters are a type of transmitter, and therefore they are widely used in industries such as mines, metallurgy, steel plants, and petrochemical industries, where hazardous conditions exist. Its advantages are as follows: first, it features structural sealing with excellent sealing performance ； Secondly, it can be used in hazardous environments, offering safety and explosion protection ； Third, it features good sensitivity and high stability ； Fourth, it facilitates customers in debugging the transmitter. In addition to ensuring the accuracy of the measurement results provided by the pressure transmitter, it is also necessary to guarantee its safety in use. Therefore, it is necessary to conduct quality inspections on explosion-proof pressure transmitters. The inspection methods mainly include: 1. Checking whether the power connections of the explosion-proof pressure transmitter are correct, and whether the wiring methods meet the specified requirements, etc. 2. Use direct observation to check the integrity of the transmitter’s appearance and whether there is any looseness in its structural assembly. At the same time, it is necessary to maintain the explosion-proof pressure transmitter by cleaning it regularly to prevent dust and foreign objects from entering its interior. It is important to note that the transmitter must be powered off before cleaning it. 3. Verify the measurement range of the explosion-proof pressure transmitter, as the transmitter’s range is relevant to the selection of pressure modules and other components. 4. Since transmitters are prone to drift, when disassembling and inspecting explosion-proof pressure transmitters, it is necessary to check for any signs of drift. 5. Adjust the values such as variables, upper and lower limits of the transmitter. Note that the adjustment steps must be carried out strictly in accordance with the requirements outlined in the manual. 6. When an explosion-proof pressure transmitter malfunctions, it is often due to problems with its internal structure; therefore, it is necessary to open its cover in order to conduct an inspection. 7. When using the transmitter, it is necessary to ensure a stable power supply. At the same time, situations such as electric shock should be avoided.
