Online moisture in oil transmitter PPM-HLW-2B
Background
Moisture in lubricating oil and hydraulic oil will destroy the oil film, cause additive failure, cause corrosion of metal parts, shorten the service life of the oil, and even cause unplanned shutdown of large machinery, resulting in serious safety accidents and economic losses. For generator sets and transformers, moisture will destroy the insulating properties of oil, posing a threat to the safety of power equipment and personnel.
Introduction
PPM-HLW-2B online moisture in oil transmitter is an intelligent sensor for online measurement of oil water content. The front-end design adopts a unique moisture sensing probe, and its unique measurement technology is extremely sensitive to changes in oil moisture content. At the same time, data compensation and algorithm optimization are carried out through high-precision temperature probes, which can quickly, real-time, and continuous online monitoring of oil moisture content indicators. Provide strong support for the reliable operation of valuable equipment.
