Compact Transmitter
Compact Transmitter
Product Code : EE381 EE381
Product Description

Our enterprise has gained immense recognition in manufacturing, exporting and supplying quality assured Compact Transmitter. The transmitter provided by us is mainly used for the measurement of water content in oil. Suitable for online monitoring of moisture in insulation and lubrication oil, this transmitter is essential for the long-term performance and preventive maintenance of machinery and plant. Additionally, this Compact Transmitter is manufactured by our deft professionals utilizing optimum grade components and ultra-modern techniques in tune with set international norms.

Features:

  • Compact design

  • Easy installation

  • Long operational life

  • Impeccable performance

Humidity measurement in oil

Similar to the humidity in the air, the water content in oil can be indicated by the absolute value in ppm or by the relative value a ppm (mass of water/ mass of oil) aw (actual water content as fraction of the water content in saturated oil) aw= 0 corresponds to water- free oil, while aw=1 indicated saturated oil. aw measurement with the EE 381 transmitter is based on the outstanding long term stability and resistance to pollution of the E+E capacitive sensor elements series HC

The measured physical quantities are water activity aw and temperature T. with these quantities EE 381 calculates the water content x (ppm) in mineral transformer oils. Calculation of water content (ppm) in non- mineral oils and lubrication oils can be achieved by programming the specific parameters of the oil into the EE 381.

Outputs

  • The EE381 transmitter has two freely selectable and scaleable outputs for water activity, water content or temperature.

  • The EE381 switch with two relay outputs is designed for control and alarm purposes. The status for early warning and main alarm is indicated by LED's.

  • Adjustment of the aw/T/ppm set point and hysteresis can be achieved with the optional configuration software.
