Product Description

The Deeter LVCS-FP continuous vertical explosion proof level sensor is a magnetic float on a reed switch or Hall Effect sensor stem for control and indication of a liquid level while in a potentially explosive atmosphere.


Features include:

  • ATEX and IECEx approved.
  • Standard lengths or custom length sensor stems up to 6 Metres.
  • Stainless steel 316L housing and wetted components.
  • Suitable for gas and dust environments.
  • IP68 Ingress protection.
  • Reed switch or Hall Effect sensing technology.
  • Voltage and current loop analogue output.
  • Programmable set point triggers.
  • M20 and ½”NPT cable connections.
  • Custom mounting options available.
  • Narrow sensor stem and mounting for tanks without internal access.
  • Suitable for high liquid temperatures.
  • Can be specified for liquid temperatures down to -55°C

The LVCS-FP explosion proof level sensor holds ATEX & IECEx Ex d certification for use in most regions worldwide.
