Gas detectors – reliable safety in any environment

The DG-22/NL-Nstd gas detector is a device designed for continuous monitoring of carbon monoxide (CO) concentration in industrial and enclosed spaces. Its task is to detect dangerous gas levels early, minimizing the risk of poisoning and ensuring safe working conditions. Thanks to its design and functionality, this detector works well in both industrial applications and public buildings.

Construction and operating principle

The DG-22/NL-Nstd detector uses a semiconductor sensor to precisely measure the concentration of carbon monoxide. It has two factory-set alarm thresholds that activate optical signaling when permissible levels are exceeded. An additional threshold, corresponding to the upper measurement range of the sensor, is also signaled optically. The device is powered by the system, simplifying its integration with existing infrastructure. Compact dimensions (110 x 140 x 55 mm) allow for easy mounting in various locations.

Advantages and benefits

• High sensitivity and precision: The semiconductor sensor provides an accurate measurement of carbon monoxide concentration, allowing for a quick response in the event of a hazard.
• Two alarm thresholds: Alarm thresholds set during production guarantee reliable warning of exceeding permissible CO levels.
• Built-in optical signaling: A multi-colored LED lamp informs about the detector's status and exceeding the alarm thresholds, providing immediate visual information.
• Easy integration: System power supply simplifies connecting the detector to the existing electrical installation.
• Expandability: The detector can cooperate with control modules such as MD-1.A/T, MD-1, MD-2, MD-4 and MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, allowing for the creation of a comprehensive gas monitoring system.
• Replaceable sensor: The ability to replace the sensor ensures long-term operation of the device and minimizes maintenance costs.
• Calibration: The device is calibrated to order, ensuring measurement accuracy immediately after installation.
• Durable construction: Splash-proof sensor cover (IP44) protects the device from moisture and mechanical damage. The possibility of using an additional mechanical cover AR-1 increases the detector's resistance in harsh industrial conditions.

Applications

The DG-22/NL-Nstd detector finds application in a wide range of facilities and installations:

• boiler rooms
• garages
• car repair shops
• industrial plants
• warehouses
• production halls
• public buildings (schools, hospitals, offices)

The device works perfectly everywhere where there is a risk of dangerous carbon monoxide concentration – a colorless and odorless gas that poses a serious threat to human life and health. Remember to calibrate the device regularly according to the manufacturer's recommendations to ensure its proper operation for a long time.
