Ammonia gas detector – reliable protection and precise measurement

The DG-41/M-Nstd gas detector is an advanced device designed for continuous monitoring of ammonia concentration in rooms. It utilizes a semiconductor sensor, providing high sensitivity and measurement accuracy. The detector is particularly useful in industrial plants, logistics centers, and public facilities, where the presence of ammonia may pose a threat to health and life. The device signals exceeding permissible gas concentration levels both visually (with LEDs) and by transmitting information to a digital supervisory module via RS-485 communication with the MODBUS RTU protocol.

Construction and functionality

The DG-41/M-Nstd detector is characterized by a solid construction and easy installation. It has a splash-proof housing (IP44) made of high-impact ABS, which ensures its durability even in harsh environmental conditions. Two cable glands facilitate connecting subsequent detectors in the system. The built-in microprocessor ensures stable operation and also enables semi-automatic addressing in the digital network without the need to open the housing. Additionally, the detector has a thermal compensation circuit and a history of alarm states, which facilitates event analysis and system diagnostics. A replaceable sensor module simplifies maintenance and reduces operating costs.

Application and benefits

• Wide range of applications: ideal for monitoring ammonia concentration in various industrial and public facilities.
• High measurement accuracy: thanks to the use of a semiconductor sensor, the detector provides precise measurement results.
• RS-485 communication: enables integration with monitoring and control systems, providing central air quality monitoring.
• Easy installation and maintenance: a splash-proof housing and a replaceable sensor module facilitate mounting and servicing the device.
• Reliability and stable operation: the built-in microprocessor and thermal compensation circuit guarantee stable detector operation in various environmental conditions.
• Calibration: The detector is factory calibrated for a range above 500 ppm ammonia, ensuring it is ready to use immediately after installation.
• Alarm signaling: The built-in LED optical signaling informs about exceeding permissible ammonia concentration levels.
• 24V= power supply: Standard power supply voltage simplifies integration with existing electrical infrastructure.

The DG-41/M-Nstd detector is an investment in safety and work comfort, which allows you to continuously monitor air quality and minimize the risk of hazards related to the presence of ammonia. The device is intended for indoor use and should not be used in areas at risk of explosion of gases, vapors or dust.
