Electromagnetic flowmeter transmitters are bound by two aspects when measuring low-temperature media: one is the low-temperature resistance of the data, the transmitter of the electromagnetic flowmeter has a small output signal, it is necessary to take care to prevent annoyance, the temperature and pressure used It cannot be too high, and the temperature used at that time does not exceed 200°. For those media above minus 20 degrees, usually electromagnetic flowmeter fabric materials are made of PTFE. PTFE is the most stable chemical plastic, but thermal expansion and contraction are more serious, which simply causes electrode leakage.The second is the electrical insulation of the electromagnetic flowmeter transmitter. If it is used for the measurement of low-temperature media without special treatment, the appearance of condensation or condensation on the outer wall of the measuring tube and the transmitter will occur briefly, which will cause When the signal is broken, the insulation resistance between the circuit and the case drops, or even a short circuit.The reputation of Sichuan Huikeda electromagnetic flowmeter in the industry and customer feedback are satisfactory: high precision, durability, long service life, low failure rate, and good after-sales service. These are the customer’s comments on us. The customer’s affirmation of Sichuan Huikeda is the driving force for our progress. We strive to develop new technologies, improve product performance, use high-quality materials, and be meticulous in product quality to ensure a production test pass rate of 100 %.
