APPLICATION:
The G.R.I. 2826 Detector was designed in response to a direct request
for a small electronic sensor capable of
detecting non-volatile liquids in remote hard to reach locations. The sensor, in
conjunction with your favorite wireless transmitter, can be used to detect and report the
encroachment of non-volatile liquids into an isolated sensitive location.
DESCRIPTION:
The G.R.I. 2826 Detector is an internally powered, microprocessor
controlled device that samples the conductivity
between any two adjacent sensor points located on the bottom of the device. Power
consumption is less than 1 micro-amp while in the standby mode. This allows for an
extended duty cycle.
Relay contacts are latched in an open or closed position based on the conductivity
measured between the sensors. External wire connections are provided to allow access to
the "C" form relay contacts for output control of an external device.
INSTALLATION INSTRUCTIONS:
To install the G.R.I. 2826 Detector, place the unit where liquid is most
likely to accumulate. Clean and dry the desired placement location. A smooth surface is
preferable and preparing surface by using an alcohol wipe is recommended. Remove
protective paper from double sided tape, then stick the unit to the cleaned surface. To
connect the 2826 Detector wires to an external device, see the installation instructions
for that device.
