Gas detector DG-P4E1/M ammonia, 100ppm, from -40°C, electrochemical sensor

Gas detectors – reliable protection against hazards

Gas detectors of the DG-P/M series are devices designed for continuous monitoring of harmful substances in the air. Their task is to measure the gas concentration and, in the event of exceeding permissible norms, activate an alarm signal and transmit information to the central supervisory module via the RS-485 network. This solution is ideal for industrial plants, logistics centers, and public utility facilities, where ensuring safety is crucial.

Construction and application

DG-P/M detectors utilize interchangeable sensor modules – semiconductor, electrochemical, or optical (Infra-Red). This design simplifies maintenance, simplifies calibration, and reduces operating costs. These devices are used in large rooms exposed to emissions of toxic or explosive gases. It is important to remember that DG-P/M detectors have a standard construction and cannot be used in explosion-hazardous areas.

Key features and benefits

• Versatility: ability to select a sensor for a specific application – ammonia (NH3) in the range of 0-100 ppm.
• Alarm signaling: built-in LED optical signaling informs about exceeding permissible gas concentrations.
• Communication: RS-485 communication with MODBUS RTU protocol enables integration with supervision and control systems.
• Interchangeable sensors: easy replacement of sensor modules minimizes maintenance costs and simplifies calibration.
• Thermal compensation: thermal compensation circuit ensures measurement stability even under variable environmental conditions.
• Alarm history: the detector stores a history of alarm states, which facilitates event analysis and identification of potential problems.
• Simple installation: removable screwless terminals facilitate connection of FTP cables.
• Durable housing: splash-proof housing made of high-impact ABS (IP44) provides protection against moisture and mechanical damage.
• Software configuration: possibility of configuring detector settings using dedicated "DETnet View" software.
• Calibration: all detectors are calibrated in their own GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150).

This detector model, DG-P4E1/M, is specifically designed for detecting ammonia in a concentration range of up to 100 ppm, and its operating temperature range starts from -40°C, making it suitable for use in harsh environmental conditions. The electrochemical sensor provides precise and reliable measurements.
