Gas detector DG-PV1R2 methane, 100% LEL, IR sensor

Methane detector with IR sensor – reliable safety

The DG-PV1R2 gas detector is an advanced device designed for continuous monitoring of methane concentration in the air. It utilizes proven infrared (IR) technology, ensuring high precision and reliability of measurements. The detector is ideal for industrial applications and enclosed spaces where early detection of potential gas leak hazards is crucial. The device emits a 4-20mA signal, allowing easy integration with various alarm and control systems.

Functionality and construction for professionals and users

Detectors from the DG/PV series, to which the DG-PV1R2 model belongs, are characterized by a modular design. This means that the measuring sensor can be easily replaced, facilitating servicing and calibration of the device. The detector works with control panels from various manufacturers, accepting 4-20mA or 2-10V current or voltage signals. Built-in optical signaling (two LEDs) informs about exceeding the permissible gas concentration levels and the technical condition of the detector – including the need for calibration. The use of thermal compensation circuitry ensures stable readings even under changing environmental conditions.

• Replaceable sensor: Quick and easy sensor replacement minimizes downtime and operating costs.
• Two signal outputs: Flexibility in connecting to various control and alarm systems (4-20mA and 2-10V).
• Optical signaling: Immediate information about the detector status and hazard detection.
• Thermal compensation: Precise measurements regardless of ambient temperature.
• Splash-proof housing (IP44): Provides protection against moisture and dust in typical industrial conditions.
• Expandability: Option to mount a mechanical guard (AR-1d) or a ventilation duct housing increases the range of detector applications.

Compliance with standards and measurement accuracy

GAZEX detectors are factory calibrated in a laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation No. AP150). This guarantees high measurement accuracy and compliance with applicable safety regulations. It should be remembered that DG/PV detectors are not intended for use in areas at risk of explosion of gases, vapors or dusts – they have a standard construction. It is also worth noting the manufacturer's recommendation regarding incompatibility with MDP, MDA or MDD modules.
