TVOC sensor | IP65 enclosure, PoM
Product description
Outdoor air quality sensor for HVAC applications. It measures temperature, relative humidity, TVOC and ambient light. It can be used in harsh environments or outdoor. The supply voltage is 24 VDC PoM - this means that Modbus RTU communication and 24 VDC power supply can be connected via one RJ45 connector. The measured values are transmitted via Modbus RTU communication. The TVOC sensor element is replaceable. In many applications, the ambient light sensor can be used to control the ventilation system in function of the occupancy of the room. All settings can be adjusted via Modbus RTU.
Additional specifications and description
HVAC transmitter for harsh environments
This HVAC transmitter measures temperature, relative humidity, TVOC and ambient light level. VOCs or Volatile organic compounds are known to cause eye, nose and throat irritations, headache, difficulty concentrating and fatigue. VOCs evaporate from substances such as cleaning products, adhesives, paints, new carpets, copiers and printers to building materials and furnishings. VOCs are a good benchmark for assessing indoor air quality. All measured values are available via Modbus RTU.
Reduced installation time
One RJ45 connector is all it takes to connect this sensor! Modbus RTU communication and 24 VDC power supply are connected via one UTP cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication. To facilitate wiring, we recommend to use a Sentera 24 VDC power supply with RJ45 connector. These power supplies offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
This sensor doesn't require any configuration. Once installed, it is ready to use. The default settings will do for most applications. If necessary, the settings can be adjusted via Modbus RTU. For example, the temperature or relative humidity range can be adjusted via Modbus RTU. Also the light intensity of the LEDs for status indication is adjustable. The Modbus register map provides a complete overview of all adjustable settings.
High quality
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is solid and offers good protection against impacts. It offers an IP65 protection against ingress of dust and water. Each sensor is calibrated and tested in our factory. We use sensor elements and components of high quality. This ensures the long-term stability and accuracy of this HVAC transmitter. To ensure optimal performance, it should be protected from direct sunlight.
