NP330-F Water in oil sensor
Measure water in oil
Whether in hydraulic oils, diesel, vegetable oils, Skydrol or other user-specific fluids: the NP330-F measures the water content up to the saturation limit. Specially calibrated for your application and the oils and fluids used – for example in drying and oil treatment plants, production plants for vegetable oils, hydraulic systems and especially for monitoring oil coolers.

Inline measurement of the absolute water content
The NP330-F water in oil sensor is designed for in-line measurement of absolute water content in ppm [mg/kg] below the saturation limit. The sensor performs its work in mineral, ester, skydrol, silicone, vegetable, diesel, refrigerator, transformer and insulating oils, among others, as well as in other customer-specific fluids.
The fields of application

How is the product maintained?
We recommend an annual recalibration and adjustment for all our sensors to be able to guarantee the exact functionality. We calibrate our sensors with state-of-the-art measurement technology in our in-house calibration laboratory. Our test equipment is one of the most accurate references in measurement and control technology. The test results are summarised in a factory calibration certificate in accordance with DIN EN ISO/IEC 17025:2018-03.
