TEK duct temperature transmitters measure duct temperatures in automated ventilation systems. They can transmit temperature measurement data to the building management system or function as controllers. In controller mode, the transmitter can control a thermal actuator or other device based on the measurement data.

The transmitter measures temperature using a PT 1000 sensor element. The transmitter converts the sensor element's resistance data into a 0–10 Vdc / 4–20 mA signal. You can select the temperature measurement range during commissioning.

The transmitter is mounted in the ventilation duct with an adjustable duct flange, allowing for easy installation and precise depth adjustment for both round and rectangular ducts. The advanced duct flange design minimizes air leakage in the duct.

You can commission the transmitter using the ML-SER commissioning tool. With this commissioning tool, you can:

• Convert the temperature output to a control output and configure the controller settings.

• Adjust the temperature measurement in the field using the one-point adjustment method.

• Change other transmitter settings.
