Gas detector DG-61/MR-Nstd HFC (Refrigerants), field calibration, proportional sensor DG-61/MR-NSTD

Refrigerant detection in refrigeration and air conditioning systems

This gas detector is designed for continuous monitoring of refrigerant concentrations, commonly known as freons (HFCs), in various facilities. Its purpose is to detect leaks early, allowing for a quick response and minimizing risks to health and the environment. The device finds application in industrial plants, logistics centers, and public buildings where air conditioning and refrigeration systems are used.

The DG-61/MR detector utilizes a semiconductor sensor characterized by high sensitivity and selectivity in detecting freons. Calibration on request ensures precise measurements tailored to the specific needs of the user. Built-in relay outputs (2 pcs) and an RS-485 interface with the MODBUS RTU protocol enable easy integration with supervision and alarm systems. Optical signaling informs about exceeding defined alarm thresholds.

Design and functionality

The device has been designed with reliability and ease of use in mind. A replaceable sensor module simplifies the maintenance and calibration process, reducing operating costs. The built-in microprocessor ensures stable operation and temperature compensation, which affects the accuracy of measurements even in variable environmental conditions. The detector also has a function to remember the history of alarm states, which facilitates event analysis. Thanks to screwless terminals, mounting and connecting the device is quick and convenient. The ability to address the detector on a digital network without having to open the housing further simplifies the installation process.

Application and benefits

• Refrigerant leak detection: Quick identification of leaks in refrigeration and air conditioning installations prevents refrigerant loss and minimizes the negative impact on the environment.
• Ensuring safety: Detecting dangerous concentrations of freons protects the health of people in potentially hazardous rooms.
• Integration with supervision systems: The RS-485 interface allows connecting the detector to a central monitoring system, providing comprehensive control over the air quality in facilities.
• Easy maintenance: A replaceable sensor module facilitates device servicing and reduces operating costs.
• Precise measurements: Calibration on request guarantees measurement accuracy tailored to individual user needs.
• Wide range of applications: The device will work in industrial plants, logistics centers, public buildings, and everywhere where air conditioning and refrigeration systems using freons are used.

The DG-61/MR detector is a reliable tool for monitoring air quality and ensuring safety in facilities using HFC refrigerants (freons). Its advanced features and ease of use make it an ideal solution for both professional installers and end-users who care about safety and the environment.
