ZYMMT-Oil-Moisture-Sensor-Online

Performance and Usages

ZYMMT Moisture Sensor is specially designed for the measurement of water content in oil. it can be portable or online use. They are certified in accordance with the regulations of the “Germanischen Lloyd (GL)” and therefore can be utilized in the maritime field as well. It is ideal

ZYMMT Moisture Sensor is a microprocessor based instrument for the measurement of moisture in terms of water activity for example in the lubrication of circulation systems or in transformer oil. The transmitter incorporates a capacitive thin film sensor. The operation of the sensor is based on changes in its capacitance as the thin polymer film absorbs water molecules.

Product Versions

The physical quantities measured are water activity aw and temperature T. With these quantities ZYMMT calculates the water content (ppm) in mineral transformer oils. Calculation of water content in non-mineral transformer oils and lubrication oils can be accomplished by downloading specific parameters of the oil.

The measured and the calculated values are available on two free scaleable and configurable analogue outputs. In addition, an optional relay output can be used for alarms and process control.
