Gas detector DD-61-Nstd Freon, calibration on request, p-p sensor, RS485 DD-61-NSTD

Gas detectors – reliable protection against refrigerant leaks

This gas detector is designed for continuous monitoring of refrigerant concentration in rooms, ensuring safety and compliance with regulations. The device uses a semiconductor sensor characterized by high sensitivity and durability. The detector is particularly useful in places where refrigerant leaks may occur, such as hotels, offices, public buildings or industrial plants.

Signaling and communication for quick response

If defined alarm thresholds are exceeded, the detector activates both optical and acoustic signaling. In addition, alarm information is sent to the control module via the RS-485 port with the MODBUS RTU protocol. This enables remote monitoring of the installation status and a quick response in the event of a failure. The NO/NC contact output allows integration with existing alarm systems or automatic device shutdown.

Flexibility and ease of use

The DD-61-Nstd detector is distinguished by a replaceable sensor module, which greatly simplifies maintenance and reduces operating costs. Device calibration can be performed on request, ensuring accurate measurements for specific needs. Configuration is done using the dedicated DETnet View software. The device is powered by 12/24V= and has a splash-proof housing (IP44), which increases its resistance to environmental conditions. The use of removable screwless terminals simplifies the mounting and connection of shielded telecommunication cables. A built-in microprocessor ensures stable operation and a thermal compensation circuit minimizes the impact of temperature changes on measurement results. The detector has a history of alarm states, which facilitates the analysis of the causes of failures.
