RTD FREEZER TRANSMITTER
SERIES SENSOR
Installation & Operation Instructions
GENERAL INFORMATION
The ACI RTD Freezer Series sensors and transmitters
are single point sensors that output 4-20 mA with an
optional voltage signal output of 1-5VDC or 2-10VDC
signal to BAS or controller. All ACI/TT and TTM
temperature transmitters can be powered from either
an unregulated or regulated 8.5 to 32 VDC power
supply.
MOUNTING INSTRUCTIONS
ACI's Freezer Series sensor includes a transmitter
with enclosure and a 3/16" diameter stainless steel
probe. The transmitter needs to be mounted in
environments with ambient temperatures above -40
°C (-40 °F) - see SPECIFICATIONS (p. 4). The freezer
probe's operating temperature range is -200 °C (-328
°F) to 200 °C (392 °F).
TRANSMITTER ENCLOSURE MOUNTING
The transmitter must be mounted outside of the
freezer/cooler. On Vertical units, mount on the top of
the freezer see Figure 3 (p. 2). On Horizontal units,
mount on the backside or side of the freezer. Attach
the base directly to the wall by using double sided
tape.
WIRE INSTALLATION
ACI recommends installing the wire through the
door seal, probe access port, or cooler wall. On
horizontal units, the preferred method is using the
rear door seal as shown in Figure 4 (p. 2). On vertical
units, remove the rear panel. There is typically a
probe access hole. Probe and wires can be ran into
that access hole. Alternatively, you can drill a hole
just larger than the diameter of the wire (0.125"
(3.175 mm)) through the wall. From inside the
cooler/freezer, push the wire through the hole. Use
mounting clips to secure the wire to the interior wall
or shelving. Use silicone caulking to seal the hole
around the wire.
SENSOR MOUNTING
Bullet Probe sensors can be wrapped around a shelf
as shown in Figure 5.
