Leak Detection Sensors
line of water detectors are designed to meet any customer needs.
From point detectors to zone detection to direct-read, we offer
a range of products broad enough for any application.
have been providing the finest in high-tech solutions to industry's
monitoring and control needs since 1987. We were the first company
to develop a complete line of water detection products that could
cover any customer requirement.
sensing devices range from point leak detectors to direct-read
cable systems which can pinpoint a leak along a 200 foot zone
with an accuracy of 1%.
sensors can be used as stand-alone monitors, their output relays
configured to trigger an audible alarm. Alternately, these can
be tied into on of Darwell's information gathering units or annunciator
panels. These units add powerful features to the monitoring system,
such as full programming and remote paging,
the ultimate in monitoring, the water detection system may be
brought into a Windows PC, using Darwell's SitePRO Evolution software.
SitePRO provides the ability to create custom graphical interfaces
to identify and locate detected leaks. SitePRO removes the limits
found in other monitoring and control systems.
Water Leak Detection
Perhaps the most important application of water detection is the
monitoring of a specific high-impact trouble spot, like an emergency
drain pan. Darwell's line of point water detectors are designed
around just such a need.
gold plated probes and microchip technology, all of our point
detectors offer the highest level of confidence in point water
detection. Some applications well suited for these packages include:
· Water heater emergency drain pans
· Air conditioner condensation drain pans
· Under-the-floor computer room monitoring
· Flood drains
Drain Detectors for HVAC
A drain pan mounted version of the WD-1. This unit is ideal for
use in emergency drain pans for HVAC, water heaters, etc.
· Gold-plated sensing probes
· Non-powered relay outputs for control of other systems
· Available with fail-safe circuitry (DD-1S)
· Powered by 12-24 volts AC or DC
· Relays rated at 1 Amp @120 VAC
· Height adjustable probe, galvanized steel
DD-1 and DD-1S may be monitored by the same monitoring panels
as the WD-1 above.
Air Conditioning Drain Detectors
A drain pan or drain line mounted sensor shuts down the cooling
before a leak can flood your home or business. I deal for add
on or new construction. Rooftop units or split systems.
Water Heater Leak Detector
A drain pan mounted version with inlet water shut off valve designed
specifically for water heaters. This kit makes water heater floods
Zone Water Detection
Many situations require monitoring large areas for the presence
of water. The Darwell AT1-M modular zone water detector module
provides an excellent solution for these needs. This unique technology
combines proven reliability with the utmost in flexibility. The
low maintenance sensing cable provides the AT1-M with the suitability
for a wide range of applications, including:
· Perimeter monitoring
· Pipe leak detection
· Under-floor detection
· Air conditioner vicinity monitoring
Zone Sensing Cable
AT1-15M, AT1-25M, AT1-30M, AT1-50M
Used in conjunction with the AT1-M module this unique sensing
cable is designed to absorb moisture and activate the AT1-M's
output relay when water levels are sufficient to complete an electrical
circuit. Best of all, the sensing cable is non-destructive, so
that when the water evaporates, the unit may be automatically
reset with no need for cable replacement. Cables can be coupled
together up to 100 feet.
· Non-destructive sensing cable
· Durable mesh cloth construction
· Self locking cable connectors
Modular Zone AC Kits
AT1-AC1, AT1-AC2, AT1-AC3
One of the most common applications of the Modular Zone water
detection system is for monitoring leaks in and around HVAC units.
The AT1-AC Kits contain all the components necessary for fast
and easy installation for AC unit.
· One AT1-M Module
· One AT1-XXM sensing cable (XX = 25, 30 or 50 foot cable)
· The appropriate number of self adhesive mounting clips
· One end-of-line resistor
· 15' Pre-wired electrical connection cable
