Gas detector DG-1R5/MR propane-butane, 10/30% LEL, IR sensor

Propane-Butane Gas Detector – Reliable Protection for Your Installation

This digital gas detector is designed for continuous monitoring of propane and butane concentrations in rooms. The device, utilizing an Infra-Red sensor, provides fast and precise detection of potential hazards, which is crucial for both user safety and the integrity of the gas installation. The DG-1R5/MR detector signals exceeding permissible gas concentration levels with an optical signal and by changing the state of the built-in relays, and also transmits information to the central monitoring system via the RS-485 interface.

Functionality and Application

The DG-1R5/MR detector finds application in a wide range of facilities, from industrial plants and logistics centers to public buildings. It is particularly useful in large rooms where there is a risk of explosive or toxic gas emissions. Thanks to the replaceable sensor module, device maintenance is simple and economical – replacing the module allows for quick calibration and minimizes operating costs. It is worth remembering that this detector has a standard construction and should not be used in explosion-hazardous areas.

Key Features and Benefits

• Precise Detection: The Infra-Red sensor provides high accuracy in measuring the concentration of propane and butane in the range of 10/30% LEL (Lower Explosive Limit).
• RS-485 Communication: Enables integration with digital gas detection systems and remote monitoring of device status. MODBUS RTU protocol ensures compatibility with most building and industrial automation systems.
• Two Alarm Thresholds: Allow for flexible adjustment of the detector's sensitivity to specific working conditions and safety requirements. Possibility of setting measurement mode for electrochemical and Infra-Red sensors.
• Built-in Relays: Two relays with NO/NC contacts allow direct control of alarm devices or shutting off the gas supply.
• Replaceable Sensor Module: Facilitates maintenance, calibration and reduces operating costs – the module can be easily replaced without replacing the entire detector. Compatibility with modules from the DG/F and DG/P series further increases system flexibility.
• Robust Construction: The housing made of high-impact ABS/PC ensures durability and resistance to mechanical damage. Protection class IP54 for electronic circuits and IP44 for the sensor cover guarantees reliable operation even in harsh environmental conditions (with recommended mounting position).
• Alarm Status History: Allows analysis of the causes of alarms and optimization of the gas detection system.
• Software Configuration: Dedicated configuration software "DETnet View" enables easy configuration of detector settings and remote monitoring of its operation (available from the manufacturer).
• Calibration: All detectors are calibrated in their own GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees their measurement accuracy and reliability.

The DG-1R5/MR detector is an investment in safety that helps avoid serious consequences related to gas leaks – from health hazards to material losses. Its reliability, precision and ease of use make it an ideal solution for both professional installers and end users.
