Gas detector DG-1R5/MR-Nstd propane-butane, field calibration, IR sensor DG-1R5/MR-NSTD

Propane-butane detector with infrared sensor

This gas detector, designed for continuous monitoring of propane-butane concentration in premises, is a key element of GAZEX gas detection systems. It utilizes advanced infrared (IR) sensor technology, ensuring high precision and reliability of measurements. The device signals exceeding defined alarm thresholds both visually (with LEDs) and by changing the state of built-in relays, and also transmits information to the control panel via RS-485 communication with the MODBUS RTU protocol.

The DG-1R5/MR-Nstd detector is an ideal solution for both gas system installers and end-users seeking effective protection against gas leaks. Its modular design with a replaceable sensor facilitates servicing, calibration and reduces operating costs.

Functionality and application

The device is designed to operate in a Digital Gas Detection System, where it provides continuous monitoring of gas concentration in monitored areas. The alarm signal is triggered when set values are exceeded, informing about a potential hazard. The detector finds application in:

• industrial plants,
• logistics centers,
• public buildings,
• rooms with increased risk of flammable gas emissions.

It is important to remember that the detector should not be used in areas at risk of explosion of atmospheres containing gases, vapors or dust.

Characteristic features and benefits

• High measurement accuracy: The infrared (IR) sensor guarantees accurate detection of propane-butane even at low concentrations.
• RS-485 communication: Enables integration with central monitoring and control systems using the MODBUS RTU protocol.
• Two alarm thresholds: Allow for flexible adjustment of the detector's sensitivity to specific working conditions. Measurement mode setting possible.
• Replaceable sensor module: Facilitates servicing and calibration, reducing operating costs. Module replacement does not require specialized knowledge.
• Solid construction: A housing with IP44 protection degree ensures resistance to atmospheric conditions and mechanical damage.
• Fast response time: Provides immediate information about the detection of a dangerous gas concentration.
• Alarm history memory: Enables analysis of events and identification of potential problems.
• Easy installation and configuration: Thanks to screw connections and intuitive configuration software “DETnet View”, installation and commissioning are quick and easy.
• Laboratory calibration: Each detector is factory calibrated in an accredited GAZEX laboratory in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees its accuracy and reliability.
