Beschrijving

The DSVCG channel sensor, suitable for 24 VAC or VDC power supply, measures TVOC, temperature and relative humidity. It has a separate output for each of these measured values. You can use it as a transmitter to pass on the measured values to a building management system, but if you want to control proportionally, you can of course also use it as a controller. The housing is designed in such a way that it fits perfectly over a 68 mm flush-mounted box. This allows the cabling to be neatly concealed. It also has an integrated light sensor and requires 18 to 34 VDC or 15 to 24 VAC power supply, and for the output you can choose between 0 - 10 VDC / 0 - 20 mA / PWM. As always with the new generation of sensors, this sensor is equipped with Modbus RTU communication.

Indoor Air Quality Based on Temperature, Humidity and TVOC
Controlling indoor air quality is not easy. But you would like your sensor to take everything into account. Well, this HVAC transmitter measures temperature, relative humidity and TVOC in air ducts. Based on the temperature and humidity, the dew point is calculated. This sensor performs best when mounted in a straight section of ductwork. Avoid installing in turbulent air zones near filters, fans, cooling coils, etc. Position the sensor correctly with respect to the airflow direction. Refer to the mounting instructions for more detailed information. Volatile organic compounds
VOCs are a large group of chemicals found in many 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 present in our daily lives include: benzene, xylene, ethylene glycol, formaldehyde and methylene chloride. Common sources include paints or varnishes, new carpets, adhesives, 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 duration of exposure. Inhaling low levels of VOCs over a long period of time may increase the risk of health problems for some people, especially those with asthma or who are particularly sensitive to chemicals. Since VOCs refer to a group of chemicals, each has its own toxicity and potential to cause different health effects. Inhaling high levels of VOCs has been known to cause eye, nose, and throat irritation, headaches, drowsiness, nausea, impaired concentration, and fatigueEasy 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 gives a complete overview of all adjustable settings.

Three-wire connection
This sensor is available in different versions depending on the required power supply. This DSVCG version can be connected with three wires and is suitable for both a 24 VDC and 24 VAC power supply. This is very useful as a replacement in existing installations. The GND terminal of the power supply voltage and the GND terminals of the analog outputs are connected via the printed circuit board. This allows the sensor to be connected with three wires (in the case of a 24 VAC power supply it MUST of course be connected with three wires).

Air ducts
The housing is optimized 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.
