HVAC sensors&transmitters

These HVAC sensors measure temperature and relative humidity. The ambient light detection can be used to distinguish between day- and night regime. The values measured by the sensors are available via the analogue outputs and via Modbus RTU communication. The algorithm of the intelligent sensors controls a single output based on the measured temperature and relative humidity. They can directly control an EC fan, an AC fan speed controller or a damper actuator. Demand based fan speed control made easy! The sensors for indoor applications offer a clear, visual indication via the green, yellow and red LED indicators. Click the product images for more details.

These HVAC sensors measure temperature, relative humidity and TVOC. TVOC means Total amount of Volatile Organic Compounds. It is a reliable standard for determining air quality. The ambient light detection can be used to distinguish between day- and night regime. The values measured by the transmitters are available via the analogue outputs and via Modbus RTU communication. The algorithm of the intelligent sensors controls a single analogue output based on the measured temperature, relative humidity and TVOC.

These sensors only measure temperature. The digital temperature sensors have Modbus RTU communication. They transfer the measured temperature in a Modbus RTU register and into an analogue output (0-10 V). Our product range also contains passive temperature sensors. These sensors do not require a supply voltage. The measured temperature is converted into a resistance value. Next to ambient temperature measurement, we also have solutions to measure wall temperature or water temperature (external temperature measurement of hot water pipes).

The electronic components and pcbs of these HVAC sensors are treated with a corrosion protective and ammonia resistant coating. This makes the sensors extremely suitable for the agricultural sector or applications with high humidity.
