WD-100-50 – GREYSTONE

WD-100-50
GREYSTONE
WATER DETECTOR – WD100 SERIES
DESCRIPTION:
The WD100 is a microchip-based device that uses
gold-plated sensing probes to detect the presence of
water or other conductive liquid. The WD100 is powered
by an AC or DC source, 14 – 30 volts. It features normally
open and normally closed (form C) relay contacts rated at
5A @ 120 VAC/30 VDC for connection to a monitoring
system, or direct control of another device. The mounting
legs will allow a sensing height adjustment from 0″ to
1/2″. The WD100 is designed to signal an alarm if one or
more of three conditions are met: water is detected,
power is lost to the unit, or if there is an internal failure.
The WD100 provides the highest level of water detection
con¬dence.
The WD-102 operates on the same principle as the
WD-100 but comes with a 5 ft. remote probe. For custom
lead lengths please contact Greystone.
The WD-100-xx Series c/w the speci¬ed length of
conductivity cable. See ordering information for available
lengths.
