About the Duct Temperature Transmitter

This duct temperature transmitter is designed for single point monitoring. It is available with
two probe lengths and enclosures to fit commercial and light-industrial applications. The duct
temperature transmitter provides a 4…20 mA current signal proportional to the sensed
temperature and is loop powered.

The temperature transmitter is designed to convert 1000 ohm RTD signal into an analog output
with ±0.15 °C Class A, ±0.30 °C Class B, and 0.1% FSO accuracy for the board.

Duct Temperature Transmitter 3

Install the Duct Temperature Transmitter

The duct type probes monitor a single point temperature within the duct. Follow these steps to
install the duct temperature transmitter.

1. Drill a 6.35 mm (0.25 in.) hole in a straight section of duct away from heating, cooling,
or humidifier elements.

2. Select a probe length that places the sensor well into the duct.

Probes are tip sensitive, this helps to avoid errors due to laminar flow.

3. Install the probe through the hole.

Wire and Connect the Duct Temperature Transmitter

Follow these steps to wire and connect the duct temperature transmitter.

IMPORTANT

1. Disconnect the power supply before making any connections to prevent electrical shock
or equipment damage.

2. Connect the transmitter to the controller using 14…22 AWG wire.

Use shielded cable for the highest noise immunity. The unit comes factory set for
4…20 mA loop powered operation with only the PWR and OUT required. The COM
terminal is used for voltage output types or for AC power.

IMPORTANT

3. Follow the example wiring diagram and make all connections in accordance with
national and local electrical codes.

4. Ensure the controller Analog Input (AI) matches the transmitter output signal type
before power is applied.

The device is reverse voltage protected and will not operate if connected backwards.
Follow specification ratings or inaccurate readings may result.

Follow anti-static precautions to prevent damage to the device.

Do not route signal wires in the same conduit with power cables as signal
degradation may occur.

Operation

1. Allow the product to warm-up for 20 minutes before you attempt to verify accuracy of
the transmitter.

2. Measure the signal by inserting a mA meter in series with the OUT terminal.

The signal should read between 4…20 mA.
