INTRODUCTION
The single point, all purpose duct/immersion temperature sensor utilizes a
precision sensor that is encapsulated in 6 mm (0.236”) OD, 304 series stainless
steel probe and is available in various lengths. All probes provide excellent heat
transfer, fast response and resistance to moisture penetration. A compact ABS
enclosure with a hinged and gasketed cover is provided for ease of installation.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning
the temperature sensor. Failure to follow these instructions may result in
product damage. Do not use in an explosive or hazardous environment, with
combustible or ammable gases, as a safety or emergency stop device or in
any other application where failure of the product could result in personal
injury. Do not exceed the device ratings.
MOUNTING (DUCT)
The duct temperature sensor installs directly into any air duct with several lengths
available for a wide range of duct widths/diameters. Please select a suitable installation
area in the middle of the duct wall. To achieve the best reading, do not place in an area
where air stratication may be present. Mount the sensor at least 1.5 m (5 ‘) in either
direction from elbows, dampers, lters or other duct restrictions. Avoid areas where the
sensor is exposed to vibrations or rapid temperature changes.
Once a suitable spot is selected, drill a 9.5 - 12 mm (3/8”- 1/2“) hole for the probe.
Slide the probe in the drilled hole until the enclosure is ush against the duct. The
airow direction is not important. Secure the enclosure to the duct with (2) #10 x 25
mm (1”) self tapping screws (not provided). Tighten screws until the enclosure is tight
against the duct and ensure there is no movement of the enclosure as shown in Figure 1.
A foam gasket on the back of the enclosure provides a tight seal against any air leaks.
MOUNTING (IMMERSION)
The temperature sensor must be installed into a thermowell. Failure to use a
thermowell will create leaks and could damage the sensor. Install the thermowell as
recommended in Figure 2. For complete thermowell installation instructions, please
refer to installation instructions provided with the thermowell.
It is recommended to use heat conductive compound. Prior to installing the sensor
inject a liberal amount into the thermowell and/or on the tip of the sensor. Slide the
probe into the thermowell until it makes contact with the bottom of the thermowell.
Tighten the set screw to secure the probe in the thermowell. See Figure 3.
The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on
the latch on the right side of the enclosure. At the same time pulling on the cover, as
illustrated in Figure 4.
A 1/2" NPT threaded connection hole is provided in the bottom of the enclosure.
Screw the EMT connector or cable gland connector in until tight. See Figure 5. It is
recommended that weatherproof conduit or cable gland ttings be used. The E style
enclosure includes 1/2" NPT to M16 thread adapter and cable gland tting.
Make wiring connections as per the “Wiring” illustrations on Page 2.
Swing door closed until securely latched. For added security, 2 screws are provided that
may be installed in the integrated screw tabs. See Figure 6.

WIRING
• Use 18-24 AWG shielded wiring for all connections. Do not locate the device wires in the same conduit with wiring used to supply inductive
loads such as motors. Make all connections in accordance with national and local codes.
• Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wiring diagrams below.
• All thermistors and most RTD’s are a two wire hook up and are not polarity sensitive. See Figure 7.
• For RTD’s that are 3 wire connection see Figure 8.

TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors, long wire runs can add
signicant error to the readings. Use the following chart to
determine errors due to wire resistance or consider using a
1000 ohm sensor or a transmitter for better accuracy. Locate
the type of wire being used. Multiply the total length of the
wire (distance from the controller to the sensor and back)
by the number found in the chart below for total resistance.
