ZYMMT Oil Moisture Sensor Online

Quick Details

Power supply: 24V AC/DC

Water content:

Gas content:

Particles size:

Application: Online moisture testing


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.

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.

Basic Features and Options:

Several probes for various applications

User friendly display

Different probe mounting kits and probe cable lengths

Transmitter mounting kits for multiple installation purposes

USB connectivity for service connections via the optional

USB-RJ45 cable

Optional modules:

  • isolated power supply
  • power supply module
  • RS-422/485-module
  • LAN and WLAN interfaces
  • data logger module with real time clock
  • additional analog output module
  • relay module

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.
