Gas detector DG-8R8/EF

Carbon Dioxide Detectors – Reliable Safety and Control

The DG-8R8/EF gas detector is a two-threshold device designed to detect the presence of carbon dioxide in industrial and enclosed spaces. It utilizes an optical sensor (Infra-Red), ensuring precise measurement and high selectivity. This detector, thanks to its replaceable sensor module, is easy to operate and maintain, and its simple construction excludes use in explosion-hazardous areas.

Application and functionality

The DG-8R8/EF device finds application wherever control of carbon dioxide concentration is crucial for safety and process efficiency. It is ideal for cold storage facilities, production halls, boiler rooms and other industrial facilities. CO2 detection allows for monitoring air quality and preventing potential health hazards to employees.

• Precise measurement: The Infra-Red optical sensor guarantees accurate readings of carbon dioxide concentration.
• Replaceable sensor: Enables quick replacement of a damaged or worn element without the need to replace the entire detector.
• Wide operating temperature range: The recommended operating temperature range is 0°C to +45°C, ensuring reliable operation in various environmental conditions.
• Solid construction: The housing made of high-impact ABS/PC ensures durability and resistance to mechanical damage. Protection class IP54 for electronic circuits and IP44 for the sensor cover guarantee protection against dust and moisture (while maintaining the recommended mounting position).
• Easy installation: 2-point mounting facilitates installation of the detector in the selected location.
• RS-485 communication: Enables integration with building monitoring and control systems using the MODBUS RTU protocol.
• Optical signaling: Built-in LEDs indicate the status of the detector (alarm, failure, power supply).

Technical parameters and additional information

The DG-8R8/EF detector is characterized by low current consumption (typically 40 mA, max approx. 90 mA) with a 24V= power supply (permissible range: 10 ÷ 30V). The detector response time is from 15 to 300 seconds, depending on the model. The device is equipped with electronic circuits ensuring control of power supply, connection integrity and sensor presence. The detector weight is approximately 0.3 kg, and its dimensions are 140 x 110 x 55 mm (height, width, depth). Remember to calibrate the sensor regularly – the calibration period depends on the sensor module specification.
