STRAP ON SERIES
Installation & Operation Instructions
PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
GENERAL INFORMATION
The ACI Strap-On Series Sensor features a 1.5"
square copper plate with the sensor encapsulated
to the back side of the plate to improve the thermal
conductivity between the pipe and the sensor
when an immersion style sensor can't be inserted
into the pipe. The Strap-On temperature sensor is a
single point temperature sensor that is designed
for use with electronic controllers in commercial
heating and cooling building management
systems. It is available with multiple thermistor
and RTD options.
The Strap-On series sensor can be used to monitor
pipe sizes from 1-1/4" to 10" (31.75mm to 254mm).
The "-S" Model is designed to t around an 1-1/4" to 4"
(31.75mm to 101.5mm) pipe. The "-S10" Model is
designed to t around a 2" to 10" (50.8mm to
101.5mm) pipe. The "-S" Model can be mounted to
larger diameter pipe by adding an additional hose
clamp.
For optimal temperature measurement, follow
these tips:
• Clean the pipe with an emery cloth or file
before applying thermal grease and insulate
the sensor from the effects of ambient air.
• The sensing element is the 1.5" square copper
plate. Applying thermal grease in-between
the sensor plate and pipe is recommended,
but not required.
MOUNTING INSTRUCTIONS
If there is insulation around the pipe, remove a
section of insulation to accommodate the width
of the junction box and sensor. The sensor
should be mounted on the top or side of the
pipe. Press the sensor copper plate to the
cleaned pipe surface, and tighten the clamp
around the pipe. Take care not to overtighten
clamp to prevent damage to the copper heat
transfer plate or sensor.
