Gas detector DG-P8R/MR-Nstd CO2, measurement range on request, IR sensor DG-P8R/MR-NSTD

Carbon dioxide detector for continuous air quality control.

This gas detector is designed for continuous monitoring of carbon dioxide (CO2) concentration in various rooms. The device uses an optical sensor (Infra-Red), which ensures precise and reliable measurement. The detector is particularly useful in industrial plants, logistics centers, public facilities, and anywhere where CO2 level control is essential.

Detectors from the DG-P/MR series are designed to work with a Digital Gas Detection System, enabling integration with other devices and a central monitoring system. If defined alarm thresholds are exceeded, the detector signals this optically and changes the state of the built-in relays, and also sends information to the supervisory module via the RS-485 network with the MODBUS RTU protocol.

Construction and functionality

The device is characterized by a replaceable sensor module, which facilitates maintenance and calibration, and also reduces operating costs. The interchangeability of sensor modules allows the detector to be adapted to specific application needs. Thanks to the built-in microprocessor, the detector ensures stable and reliable operation, and the thermal compensation system minimizes the impact of temperature changes on measurement accuracy. Additionally, the detector has an alarm history and a semi-automatic addressing function in the digital network.

Mounting and applications

The detector has two cable glands to facilitate connecting subsequent devices in the system. The possibility of equipping it with an additional steel cover or a housing for a ventilation duct expands the range of applications. Screwless terminals facilitate the connection of FTP cables. It should be remembered that DG-P/MR detectors cannot be used in places exposed to the explosion of gases, vapors or dust – these are devices of conventional construction.
