  • Rod & rope type probe
  •  Probe length 250 mm to 10m

The sensing element and the container wall (or ground electrode) form a means to measure the admittance of the system with and without the intervening material. When all the parameters that affect the admittance value are kept constant then its value changes only due to the difference in material level.The sensed signal is further amplified and used to actuate the relay.The relay contacts are used for alarm or control purpose.

  • Power Supply: 24 V DC, 90-260 V AC
  • Fail-safe High/Low selection available as standard
  • Suitable for very dusty environment
  • High durability and system reliability
