The GRI 2808 Absence of Water Detector is targeted for monitoring a fluid level height. This submersible sensor can safely and reliably sense and respond to the absence of or presence of a non-volatile liquid in a wide range of environmental conditions.

The GRI 2808 series of water detectors are microprocessor controlled devices that produce and AC signal between two stainless steel probes. Depending on the conductivity measured between the two probes, a set of internal relay contacts will be latched in an open or closed position.

Sensor life span is optimized by periodically sampling for liquid at set timed intervals. Conductivity sampling between the two probes once every 2.5 minutes are used in the Standard Self Powered 2808 allowing for a 4-year expectancy. A sampling rate of once every 10 seconds is used with the Externally Powered 2808-12V providing a 15+ year life expectancy. Instantaneous triggering and custom sampling rates are also available on request.

External connections are made through the included 12 inches of direct burial cable allowing for up to a foot of total submersion, burial or harsh environmental exposure. Custom cable lengths are also available on request.

Features

  • Senses the lack of or presence of any non-volatile liquid
  • Microprocessor controlled
  • Submersible and fully self contained
  • 12” cable
