n ROOM TEMPERATURE SENSORS
This unit is suitable for either drywall or junction box mounting. The room sensor is provided with screw terminal blocks
for all connections. Remove the cover from the unit and mount the housing base to the wall using the (2) 6/32” x 1”
machine screws. Now replace the cover and tighten down using the (2) 1/16” Allen screws located on the bottom of the
enclosure.
n DUCT
Duct temperature sensors - Drill a 3/8” hole in the duct and insert the probe through the hole until the foam pad is against
the duct. Now insert the (2) mounting screws through the mounting holes in the flange and tighten them down until the
unit is held firmly to the duct.
n FLUID IMMERSION TEMPERATURE SENSORS
The ACI Fluid Immersion-type sensors are provided with a 2 ½”, 4”, or 6 ¼” insertion length, 304 series stainless steel
thermowell. The thermowell has a 1/2” NPT external or process thread and a 1/2” NPT internal or instrument threads. Heat
transfer compound may be used but is not necessary. All of the ACI thermowells will accept a probe diameter of 0.250”.
n STRAP-ON TEMPERATURE SENSORS
The ACI Strap-On sensors, are provided in a NEMA 1 rated junction box with an adjustable 2” to 5” pipe clamp. The unit
should be mounted on the bottom side of the pipe to ensure proper heat transfer and a true temperature reading. Heat
transfer compound and insulating the sensor will help the overall accuracy of the sensor. By ordering extra straps and
fastening them together, it is possible to make them fit pipes larger than 5” in diameter.
n OUTSIDE AIR TEMPERATURE SENSORS
The ACI Outdoor Air temperature sensors are provided in a weatherproof enclosure. An optional waterproof Aluminum
Bell Box or NEMA 4X Polycarbonate enclosure is also available upon request for an additional charge. All of the mounting
hardware is provided with the sensor. Be sure to mount the sensor out of direct sunlight, with the sensor probe pointing
downward.
n STAINLESS PLATE TEMPERATURE SENSORS
The ACI Stainless Plate temperature sensors are mounted on the back of a 1 Gang stainless steel plate. The foam pad will
insulate the sensor from any drafts in the wall. (2) 6/32” x 1” machine screws are provided for junction box mounting. Be
sure that the sensor is not mounted on an outside wall, due to the overall effect on the temperature readings from either
drafts or heat transfer.
