Water-in-Oil sensor | Transformer Oil analysis

The Water-in-Oil ST-100 sensor is a temperature and humidity transmitter with a fast, reliable and accurate online transmitter for water activity in oil and temperature. The ST-100 is ideal for monitoring the humidity in oil or for online moisture measurement. The ST-100 is suitable for measuring humidity in lubricating, hydraulic or insulating oils, which is important for long-term performance and preventive maintenance of machinery and equipment. Oil moisture and water activity are automatically determined by the ST-100 Water-in-Oil Sensor.

The oil transmitter measures the water activity (also aw-value) and temperature (T). Both values can be read on the display. The humidity in oil can be given as absolute humidity in ppm or relative as water activity aw value. Our sensor measure the absolute water activity (aw) in oil and temperature (T) of the user oil continuously, reliably and accurately at all times. By integrating the measurement into the oil circuit, the measurement is carried out in real time and the reaction can also take place immediately. The risk of not detecting an increase in water activity (aw) between random measurements is eliminated.

The use of our sensors not only ensures that the quality but also guarantees safety extends the service life of the oil and minimizes downtime. The Water-in-Oil Sensor ST-100 is a robust online transmitter, which informs you reliably about a transformer failure. This is an accurate and cost-effective solution for online measurements of humidity in oil. Today’s oil sensors measure many parameters. With its robust housing and excellent performance, it is perfectly suited for integration into OEM applications.
