Description

The DG-1-ME digital natural gas (methane) detector is a professional device designed to ensure the highest level of safety in rooms at risk of gas leaks, such as kitchens, boiler rooms, or bathrooms with gas heaters. Thanks to the use of an advanced microprocessor, the detector offers exceptional detection precision and high immunity to false alarms caused by external factors.

Specification

Gas detection

Natural gas (methane) - detection of explosive concentrations before reaching critical levels

Sensor type

Semiconductor gas sensor with digital signal processing

Alarm thresholds

Pre-alarm: 10% lower explosive limit (LEL); Alarm: 20% lower explosive limit (LEL)

Acoustic signaling

Built-in buzzer (piezoelectric transducer) emitting a loud sound signal

Optical signaling

Red LED indicating standby status, pre-alarm, alarm, and fault

Alarm output

NC relay output (resistive contact 40 mA / 16 V DC) for connection to the alarm control panel

Tamper protection

Tamper contact reacting to the opening of the device housing

Signal analysis

Microprocessor-based, digital with algorithm for false alarm elimination

Temperature compensation

Full digital compensation of ambient temperature influence on measurement

Self-diagnostics

Continuous monitoring of sensor efficiency and processor correctness

Power supply

Rated voltage 12 V DC (±15%); Power consumption: standby 30 mA, alarm 50 mA

Operating conditions

Ambient temperature: -10 °C to +55 °C; Internal use

Installation

Recommended ceiling installation or high on the wall (methane rises upwards)

Physical dimensions

Housing diameter: 97 mm; Height: 35 mm

Software

The device firmware is based on an advanced digital signal analysis algorithm that precisely filters data from the gas sensor. Thanks to this, the device can effectively distinguish methane from interfering gases, which minimizes the risk of triggering a false alarm. The program implements a digital temperature compensation function, adjusting alarm thresholds (10% and 20% LEL) to environmental conditions in real time. The firmware also manages the self-diagnostic system, which continuously monitors the physical state of the gas sensor and the integrity of the electronic circuit, ensuring full operational readiness and immediate reporting of any faults.
