Carbon Monoxide Detector DG-2E/N/w – reliable protection against hazard

This gas detector is designed to detect dangerous concentrations of carbon monoxide (CO) in industrial and enclosed spaces. The device, utilizing an electrochemical sensor, provides continuous air monitoring and signals exceeding permissible norms. This is crucial for the safety of people in potentially hazardous areas, as well as for the protection of installations and property.

The DG-2E/N/w detector belongs to the group of threshold, system gas detectors DG/F, characterized by high precision and reliability of measurements. Its design allows cooperation with various control modules, such as MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8 and MDP-16 – providing great flexibility in building gas detection systems.

Key features and benefits:

• Replaceable electrochemical sensor: enables quick replacement of a damaged sensor without the need to replace the entire device – reduces operating costs and downtime.
• Two alarm thresholds: factory set (NDS/NDSCh 20/100 ppm), ensure effective response to changes in CO concentration. A third threshold, signaled optically, informs about approaching the upper measurement range of the sensor.
• Built-in event history: allows analysis of the causes of alarms and optimization of the gas detection system operation (analysis available from the manufacturer).
• Calibration period expiry signal: reminds of the need for regular inspections and calibration of the device – guarantees measurement accuracy.
• Thermal compensation circuit: minimizes the impact of ambient temperature changes on measurement results – ensures stable readings even in variable conditions.
• Splash-proof housing (IP44): protects the device from moisture and dust – enables mounting in harsh industrial conditions.
• Expandability: optional mechanical covers AR-1 protect the detector from mechanical damage in places exposed to vandalism or accidental impacts. Possibility of mounting in ventilation ducts (DG/w).

Applications:

The DG-2E/N/w detector finds application everywhere where there is a risk of carbon monoxide formation:

• gas and oil boiler rooms;
• car workshops;
• industrial plants;
• underground garages;
• rooms with furnaces and fireplaces;
• warehouses and storage facilities;
• ventilation and air conditioning systems.

The device is calibrated in its own GAZEX Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which confirms its high quality and measurement accuracy. The supply voltage is taken from the control system, and the compact dimensions (110 x 140 x 55 mm) facilitate mounting even in tight spaces. It has removable terminals allowing connection of single- and multi-strand wires without the need for ferrules. The built-in optical signaling (multicolor LED lamp) informs about the device status and exceeding the alarm thresholds.
