PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
GENERAL INFORMATION
The Immersion 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 or RTD options.
For optimal temperature readings, follow these
tips:
•
Apply thermal grease to the end of the probe
before installation into thermowell (ACI Item
#102595).
•
The tip of the thermowell should be located in the
middle of the pipe.
•
The sensor thermowell should be installed against the
flow of the water, where water temperature is well
mixed (no stratification).
•
Make sure the entire thermowell is immersed. If the
thermowell is longer than the pipe diameter, the
thermowell should be installed in an elbow or Tee.
THERMOWELL INSTALLATION
ACI’s standard Immersion sensors are made to install
into a ½” NPT female thread. Typically a Threadolet or
Tee is installed into the pipe, but a hole can also be
drilled and tapped.
