Methane detector DG-1R2/M-Nstd – reliable gas presence control

The DG-1R2/M-Nstd gas detector is an advanced device designed for continuous monitoring of methane concentration in various spaces. It utilizes an optical sensor (Infra-Red), providing high precision and speed of response. The detector is a component of the Digital Gas Detection System, enabling integration with supervision and alarm systems. The device is particularly useful in places where methane accumulation may potentially occur, such as industrial plants, logistics centers, or public utility facilities.

Construction and functionality

The DG-1R2/M-Nstd detector is characterized by a modular design, which facilitates servicing and sensor replacement. The replaceable sensor module allows adaptation of the device to specific application needs and reduces operating costs. Communication is via an RS-485 port with the MODBUS RTU protocol, ensuring easy integration with existing automation and control systems. A built-in microprocessor ensures stable operation and the possibility of semi-automatic addressing in a digital network without the need to open the housing. Additionally, the detector has a thermal compensation circuit and an alarm history, which increases its reliability and facilitates event analysis.
