Ammonia detector DG-41/MR-Nstd – reliable protection against hazard

The DG-41/MR-Nstd gas detector is an advanced device designed for continuous monitoring of ammonia concentration in various industrial and public utility environments. Its task is to detect dangerous gas levels early, allowing for a quick response and minimizing the risk to health and property. The device uses a semiconductor sensor, providing high sensitivity and measurement accuracy.

Construction and principle of operation

The DG-41/MR-Nstd detector is part of the GAZEX Digital Gas Detection System, which enables integration with other devices and centralized system management. Thanks to RS-485 communication with the MODBUS RTU protocol, data from the detector can be easily transmitted to the central supervisory module. If defined alarm thresholds are exceeded, the detector signals this using a built-in optical indicator and by changing the state of the relays. The replaceable sensor module facilitates maintenance and calibration, reducing operating costs.

Application and benefits

The DG-41/MR-Nstd detector is used in:

• industrial plants where ammonia is used or produced as a byproduct of technological processes (e.g., cooling plants, chemical plants);
• logistics centers and warehouses where products emitting ammonia are stored;
• public utility facilities (e.g., sewage treatment plants) where there is a risk of ammonia leakage;
• large rooms requiring continuous monitoring of toxic gas concentrations.

Why choose the DG-41/MR-Nstd detector?

• High sensitivity and accuracy: The semiconductor sensor provides accurate measurements of ammonia concentration.
• System integration: The ability to integrate with the GAZEX Digital Gas Detection System simplifies the management of multiple detectors simultaneously.
• Easy maintenance: The replaceable sensor module simplifies calibration and reduces operating costs.
• Fast response: The built-in optical indicator and relays enable quick notification of exceeding the permissible ammonia concentration limits.
• Reliability: The built-in microprocessor ensures stable and reliable operation of the device.
• Calibration: Detectors are factory calibrated in the GAZEX Calibrating Laboratory accredited in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No. AP150).
• Versatility: Possibility of use in various industrial and public utility environments.

Additionally, the detector has screwless terminals to facilitate connection of wires and two cable glands to easily connect subsequent detectors in a network. Configuration of settings is done using the dedicated "DETnet View" software. Please note that the device is not intended for use in areas at risk of explosion of gases, vapors or dusts.
