Temperature Sensor | Duct | 24 VDC-PoM | Metal probe | L 165 mm
Product description
The DTS-M series consists of digital temperature sensors and transmitters designed for temperature monitoring in air ducts. They are powered by 24 VDC over Modbus (PoM).
These sensors measure temperatures from -30 to 70 °C using a 165 mm long stainless steel probe. The temperature data is transmitted via Modbus RTU communication.
Wiring is simplified through a single RJ45 socket, which handles both power and Modbus RTU connections. The durable, low-maintenance, and easy-to-clean design has an IP65 protection standard. The sensors are ideal for reliable temperature control systems, operating in temperatures from -30 to 70 °C and relative humidity of 5 to 95% rH (non-condensing).

Additional specifications and description
Which parameters are measured and why is it important?
This digital sensor measures temperature in air ducts. The measured values are available via Modbus RTU communication.
Temperature plays a crucial role in human comfort and overall well-being. Temperature not only affects how hot or cold a space feels, but also impacts health and productivity. It is important to create an indoor environment that ensures a general sense of comfort for everyone.
What are the configuration and customisation options?
The sensor operates within a temperature range of -30 °C to 70 °C and a relative humidity below 95% RH (non-condensing).
Modbus RTU communication is used to transmit the measured values and can be used to change all of the settings.
How is the sensor installed, and what are the power and connectivity requirements?
The metal sensor probe has a length of 165 mm and is inserted in an air duct. To ensure optimal performance, the sensor must be installed in a zone without turbulences.
This sensor can be connected with just one RJ45 connector. Power over Modbus (PoM) connects Modbus RTU communication and a 24 VDC power supply via one single UTP-cable. The measured temperature can be read out via Modbus RTU communication.

Thanks to its specially designed mounting bracket, this sensor can be easily installed on a wall or any other surface. Installing two temperature sensors at different heights on the same wall provides an effective way to monitor and control temperature stratification within a space.
What are the manufacturing quality and protection ratings?
All sensors are designed and manufactured in Europe. Each device is calibrated and tested in our factory. Only high-quality components are used, ensuring long-term stability and accuracy.
The metal probe has a smooth, closed surface. This durable, low-maintenance, and easy-to-clean design provides an IP65 protection against ingress of dust and moisture.
