Intelligente kanaalsensor temperatuur | vochtigheid, 24 VDC

The DCTHF sensor for air ducts measures temperature and relative humidity. It combines these 2 measured values in one intelligent output to which you can directly connect the EC fan or control valve. The probe of the sensor is equipped with a flexible flange with which you can attach the device to the air duct. This way the cabling can be neatly concealed. The sensor requires 18 to 34 VDC supply voltage and for the output you can choose between 0 - 10 VDC / 0 - 20 mA / PWM. As always with the new generation of Sentera sensors, this sensor is equipped with Modbus RTU communication.

Smart indoor air quality based on temperature and relative humidity
Temperature and relative humidity are the most important comfort parameters for a comfortable indoor air quality. You would prefer the sensor to take both parameters into account. Well, this sensor from Sentera can record both measured values and the sensor algorithm controls a single output . This output can control an EC fan, an AC fan speed controller or a damper actuator. The output value varies proportionally according to the measured temperature and relative humidity. For example, as the temperature or relative humidity approaches their maximum limit, the fan speed increases or the damper opens.

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 gives a complete overview of all adjustable settings.

4-wire connection
The supply voltage is 24 VDC. The ground terminals of the power supply (V-) and output (GND) are not connected internally. This means that a 4-wire cable is required to connect this sensor. Most 24 VDC power supplies offer protection against short circuit, overload and overvoltage. A supply voltage of 24 VDC increases the safety and reliability of your installation.

Air ducts
The housing is optimized for temperature and humidity 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.
