Duct temperature | humidity sensor | PoM
Product description
This HVAC transmitter measures temperature and relative humidity in air ducts.
The dew point is calculated using the measured values. The power supply is 24 V DC PoM. This means that one RJ45 connector can connect Modbus RTU communication and a 24 V DC power supply. The sensor makes use of Modbus RTU communication to transmit the measured values. It can also be used to change several other the settings.
Additional specifications and description
Why is it important to measure temperature and humidity in air ducts?
Measuring temperature and humidity in air ducts is an essential part of HVAC systems for several reasons. It is crucial for occupant comfort and helps HVAC systems operate more efficiently. Maintaining the right humidity levels is important for indoor air quality. Too high or too low humidity can lead to problems like mold growth, respiratory issues or discomfort. When warm, moist air comes into contact with cold surfaced (e.g. inside air ducts), it can lead to condensation. This can cause water damage. Monitoring temperature and humidity levels helps prevent such issues.

Designed for air ducts
This HVAC transmitter measures temperature and relative humidity in air ducts. The dew point is calculated using these measurements. This sensor works best when installed in a straight section of the air duct. Avoid installing near filters, fans, cooling coils, and other sources of turbulent air. Place the sensor correctly in relation to the airflow direction. For more information, please have a look at the mounting instructions.

Installation time is reduced
This sensor can be connected with just one RJ45 connector. Power over Modbus, or PoM, connects Modbus RTU communication and a 24 V DC power supply via a single UTP cable. All measured values are available via Modbus RTU. To make wiring easier, we recommend using a Sentera 24 VDC power supply with an RJ45 connector. These power supplies provide short-circuit, overload, and overvoltage protection. A supply voltage of 24 V DC improves the safety and reliability of your installation.

Easy to useThis sensor requires very little configuration. It is almost directly usable once it has been installed. Temperature and relative humidity are often region- and seasonal-specific. These parameters are still adjusted to the correct values during installation. The other default settings will probably be suitable for most applications. However, they can also be adjusted via the respective Modbus registers if necessary. It can, for example, be used to change the temperature or relative humidity range. The Modbus register map displays a complete list of all adjustable parameters.
High quality
This HVAC transmitter was made in Europe. In our factory, each sensor is calibrated and tested. We use high-quality sensor elements and components. This ensures the HVAC transmitter's long-term stability and accuracy. The enclosure is dust and moisture resistant to IP54 standards. The sensor element is built into the duct sensor probe. This probe has an opening through which the air flow can make direct contact with the sensor element. The sensor probe itself has an IP20 rating.
