PRODUCT OVERVIEW
The ETI
®
CIT–1, GIT–1 and SIT–6E snow and ice melting
sensors combine to reliably detect moisture and
temperature for surface snow melting and roof and gutter
de-icing applications. The CIT–1 sensor may be paired with
either the GIT–1 sensor for gutter applications or the SIT–6E
sensor for pavement applications. These sensors detect
precipitation as snow at temperatures below 38°F (3.3°C).
Control panels are signaled only if moisture occurs below
this temperature, thus saving energy and ensuring reliable
ice melting. They provide the industry’s most versatile and
cost effective automatic snow melting control when used
with any APS or EUR series control panel.
Reliability and sensitivity are key features in the CIT–1, GIT–1
and SIT–6E sensors. The solid state design, combined with
a rugged housing and epoxy potting, ensure many years of
trouble free service. Precision precipitation and temperature
sensing provide the sensitivity required for effective
automatic control. All three are NEC Class 2 low voltage
device which simplifies installation.
The CIT–1, GIT–1 and SIT–6E’s unique microcontroller
design frees their moisture sensors from ice bridging. Ice
bridging happens if incomplete melting occurs near the
heater or sensor leaving an air space. The air insulates thus
preventing effective heater and sensor operation. Additional
features prevent heater operation under conditions
favorable to heater ice tunneling.
The CIT–1 aerial snow sensor detects falling or blowing
precipitation before snow or ice begin to accumulate. This
allows the control panel to begin managing the system. This
sensor may be roof or mast mounted.
The GIT–1 mounts directly in gutters and down spouts
sensing actual environmental conditions.
The SIT–6E accurately measures pavement temperature
while reliably detecting snow and ice conditions on pavement
surfaces. A built-in hold-on timer in the SIT–6E keeps
heaters operating for an hour after snow stops to help
ensure complete snow melting. Mounting these sensors
close to the deicing heaters ensures that pavement and
sensor become dry at about the same time.
An adjustable mounting system aligns the SIT–6E with the
pavement surface. Six conduit locations add to installation
flexibility. The sensor subassembly is field replaceable without
disturbing the pavement.
