Beschrijving

This version of the multifunctional channel sensor measures indoor air quality (TVOC), temperature and humidity. It has an RJ45 connector over which both data and power are distributed. But because there is no digital-to-analog (D/A) conversion, it does not have the classic terminal blocks. And therefore also no analog output signal. This makes it a good buy. With the right firmware, it can be combined with Modbus fans or you can connect it to the RTVS transformer controller. This in turn controls the speed of your AC fan in 5 steps. This -M version of the DCVC channel sensor is also the ideal choice as a building block of a PoM Modbus network.

Indoor air quality based on temperature, humidity and TVOC
Controlling indoor air quality is not easy. You would like the sensor to take everything into account. Well, this HVAC transmitter measures temperature, relative humidity and TVOC in air ducts. The dew point is calculated based on the temperature and humidity. It has a separate Modbus register for each of the measured values, as well as for the dew point and the light intensity. Your building management system or our SenteraWeb cloud service can use these values to calculate control algorithms, send notifications, etc. This sensor functions best when mounted in a straight section of the air duct. Avoid installation in turbulent air zones near filters, fans, cooling coils, etc. Position the sensor correctly in relation to the air flow direction. Consult the mounting instructions for more detailed information.

Volatile organic compounds (
VOCs) are a large group of chemicals found in many of the products we use to build and maintain our homes and buildings. Once inside a building, they are released or evaporate into the indoor air we breathe. Common examples of VOCs that are present in our daily lives include: benzene, xylene, ethylene glycol, formaldehyde, and methylene chloride. Typical sources include paints or varnishes, new carpets, glues, cleaning products, smoking, dry cleaning, photocopiers, building materials such as foam, and burning wood. The risk of health problems from inhaling a chemical depends on the exact chemical compound, the concentration, and the length of exposure. Inhaling low levels of VOCs over an extended period of time may increase the risk of health problems for some people, especially those with asthma or those who are particularly sensitive to chemicals. Since VOCs refer to a group of chemicals, each of them has its own toxicity and potential to cause different health effects. Inhaling high levels of VOCs is known to cause eye, nose and throat irritation, headaches, drowsiness, nausea, impaired concentration and fatigue

Easy to use!
This sensor does not require any configuration . Once installed, it is ready to use. The default settings are sufficient for most applications. If necessary, the settings can be adjusted via Modbus RTU communication. For example, a different output type can be selected to make the sensor compatible with existing devices: 0-10 VDC / 0-20 mA / 0-100 % PWM. The Modbus register map provides a complete overview of all adjustable settings.

RJ45 PoM connection
This DSVC sensor is available in different versions depending on the required power supply. The power and data of this DSVCM version are supplied via a single RJ45 connection. There is no analogue output. This makes this sensor easy to connect and cost-effective to purchase. Ideal as part of a network.

Air ducts
The housing is optimised for TVOC measurements in air ducts . It offers IP54 protection against the ingress of dust and moisture. The sensor element is integrated into the probe of the duct sensor. This probe is provided with an opening so that there is direct contact between the air flow and the sensor element. The sensor probe offers IP20 protection.
