Gas detector DG-P4E2/M ammonia (selective - wastewater treatment plants), 100ppm, electrochemical sensor

Gas detectors – reliable protection of the working environment

The DG-P4E2/M gas detector is an advanced device designed for continuous monitoring of ammonia presence in the air. It is primarily used in wastewater treatment plants and other industrial facilities where there is a risk of this gas emission. The device signals exceeding permissible concentration levels, warning of a potential threat to health and life. Thanks to precise measurement and a reliable design, the DG-P4E2/M detector provides effective protection of installations and personnel.

Design and operating principle

The detector is based on an electrochemical sensor, which is characterized by high selectivity in detecting ammonia. This means that the device minimizes the risk of false alarms caused by the presence of other gases. The built-in microprocessor ensures stable operation and semi-automatic addressing in a digital RS-485 network with the MODBUS RTU protocol, which facilitates integration with supervision and control systems. Alarm signaling is carried out using a built-in LED optical indicator. The device is powered by 24V= voltage, which ensures easy installation and compatibility with most power systems.

Application and benefits

The DG-P4E2/M detector is an ideal solution for:

• Wastewater treatment plants: monitoring ammonia concentration to ensure the safety of employees and protect the environment.
• Industrial plants: control of ammonia emissions in production processes.
• Logistics centers: detection of ammonia leaks from refrigeration systems.
• Public utility facilities: ensuring safety in premises where there is a risk of ammonia emissions.

Using this detector translates to:

• Early hazard detection: a quick response to an increase in ammonia concentration minimizes the risk of negative consequences for health and the environment.
• Reliability and measurement accuracy: the electrochemical sensor provides precise measurement results, eliminating false alarms.
• Easy integration with monitoring systems: RS-485 communication with the MODBUS RTU protocol enables seamless connection to existing monitoring systems.
• Low operating costs: replaceable sensor modules facilitate maintenance and reduce calibration costs.
• Calibration standards: all detectors are calibrated in their own GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150).
• Durable construction: splash-proof housing made of high-impact ABS (IP44) ensures resistance to environmental conditions prevailing in production halls or wastewater treatment plants.
