Monitoring the moisture content of lubricating oil and hydraulic oil in large-scale continuous operation equipment, heavy machinery and other equipment plays an irreplaceable role in ensuring the normal operation of these critical devices. The presence of moisture can damage the oil film, cause additive failure, lead to corrosion of metal components, shorten the service life of oil, and even cause unplanned shutdown of large machinery, resulting in serious safety accidents and economic losses. For generator sets and transformers, moisture can damage the insulation properties of oil, posing a threat to the safety of electrical equipment and personnel.

The YA2 micro moisture sensor features a unique moisture sensing probe at the front end, which can capture real-time changes in the electrical characteristics of oil-water mixtures and compensate for data through high-precision temperature probes. Through optimized algorithms, the moisture content in the oil can be obtained. The company's unique patented measurement technology can successfully achieve accurate monitoring of moisture content in multi range oil.

Technical advantages:

1. Continuous and rapid detection of water activity (aw) in oil;

2. Accurately measure the trace water content (ppm) in oil;

3. Long term stable operation in harsh environments;

4. Convenient local calibration function;

5. High oil resistance and pressure resistance;

6. Compact structure, easy to integrate;

7. Multiple mode signal outputs.
