Gas detector DG-P8R8.EN-Nstd CO2, measuring, adjustable range, IR sensor, 4-20mA output (for PLC), economical DG-P8R8.EN-NSTD

Carbon dioxide detector for gas detection systems

This carbon dioxide (CO2) detector from the DG-P.EN series is an economical solution for continuous measurement of CO2 concentration in enclosed spaces. It utilizes proven NDIR (infrared) optical technology, providing selective and precise measurement, even in the presence of water vapor and other gases. The device is designed to work with various GAZEX control modules (MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, MDD-1, MDD-1/T, MDD-1x/T) and control panels accepting a standard 4-20 mA signal.

The DG-P8R8.EN detector is ideal for applications requiring CO2 monitoring, such as mushroom farms, greenhouses, or utility rooms. Its construction allows for reliable operation in harsh industrial conditions.

Characteristics and application

The detector is designed to operate in gas detection systems where precise measurement of carbon dioxide concentration is crucial for safety and process optimization. The 4-20 mA output signal allows for easy integration with existing building management and monitoring systems (BMS). It is important to remember that the device should not be used in potentially explosive atmospheres.

The use of an IR sensor ensures long-term measurement stability and minimizes the need for calibration – the sensor retains its properties for over 10 years in clean air. Additionally, the detector is resistant to exceeding the measurement range, which increases its reliability in variable working conditions.

Construction and user features

• NDIR measurement: The use of infrared technology ensures high selectivity and accuracy of CO2 measurement.
