Instrument failure is a problem we often encounter in our work, so what are some good ways to judge the failure and find out the problem? We have compiled 10 methods for analyzing and judging industrial instrument faults, and summarized many years of instrument maintenance experience. I hope it will be helpful to you. 1. […]

The flow signal of the electromagnetic flowmeter is based on the measured conductive liquid as the reference potential. The conductive liquid in the entire measurement pipe is regarded as a conductor with zero resistance. The two electrodes form a differential signal voltage to the conductive liquid. Therefore, if the signal contact point is unreliable, the

1. Empathy – Do the right thing “The key question is to find the key to the problem.” If you want to find opportunities for process control improvement, you need to understand and care about the operators! Not only have enough respect for their operations, but also find ways to reduce their operational interference. High-frequency

1. It is forbidden to mix signal cables and power supply cables in one multi-core cable! 2. It is strictly forbidden to stick to oil when maintaining oxygen pipeline instrument equipment. Oil-free transmitters and pressure gauges are strictly forbidden to be mixed with ordinary gauges. 3. When repairing and removing wires from the instrument, you

The lubrication cycle should be determined according to the specific situation and mainly includes the following parts: 1. Pneumatic cam deflection valves, pneumatic ball valves, pneumatic butterfly valves, and rotating parts of electric actuators; 2. Protection box, door shaft of the insulation box, and fastening bolts of the junction box; 3. Bolts and nuts for

1. When opening holes for instruments, avoid opening holes in formed pipes. 2. Pay attention to the length of the straight pipe section before and after the flow meter. 3. If there are electromagnetic and mass flow meters with grounding requirements, they should be grounded according to the instructions. 4. When welding process pipelines, the

1. Before installing the instrument, the process pipeline should be purged to prevent ferromagnetic substances retained in the pipeline from adhering to the instrument, affecting the performance of the instrument or even damaging the instrument. If unavoidable, a magnetic filter should be installed at the inlet of the instrument. The instrument itself does not participate
