About the Duct Average-temperature Transmitter

The multi-point duct average-temperature transmitter incorporates numerous precision RTD

sensors at equal distances. The transmitter is encapsulated in a soft copper probe for long lengths

or a stainless steel probe for shorter lengths. All probes provide excellent heat transfer, fast

response, and moisture-penetration resistance. The transmitter provides a high accuracy signal

with excellent long term stability, low hysteresis, and fast response.

Duct Average-temperature Transmitter 3 Mount the Duct Average-temperature Transmitter Follow these steps to mount the transmitter. 1. Install the duct average sensors onto hangers in the duct using supplied clamps. Located the sensors in a straight section of duct away from heating, cooling, or humidifier elements. The duct average sensor can be easily shaped to fit any duct size, but observe a minimum bend radius of six inches to prevent damage to wires or sensors.
