Gas detector DG-6R7/MR-SF6-Nstd SF6, calibration on request, IR sensor DG-6R7/MR-SF6-NSTD

Sulfur Hexafluoride (SF6) Detection – Reliability and Precision

This gas detector is designed for continuous monitoring of sulfur hexafluoride (SF6) concentration in various industrial and public utility facilities. It utilizes an advanced optical sensor (Infra-Red), ensuring high measurement accuracy and fast response time. The device is particularly useful wherever early detection of SF6 leaks is critical, allowing for risk minimization and ensuring safety.

Functionality and Communication

The DG-6R7/MR-SF6-Nstd detector offers extensive configuration options and integration with monitoring systems. Communication is via an RS-485 port with MODBUS RTU protocol, enabling easy data reading and remote control. It has two programmable alarm thresholds and built-in relays with NO/NC contacts, allowing for direct activation of warning or ventilation systems. Additionally, the device has a built-in optical alarm signaling system.

Construction and Application

The detector is characterized by a solid construction and compact dimensions (110 x 140 x 55 mm). A replaceable sensor module simplifies maintenance and calibration, reducing operating costs. The ability to address the detector in a digital network without opening the housing significantly simplifies the installation and configuration process. The device is powered by 24V=. This makes it suitable for demanding working conditions, and its reliability is confirmed by numerous tests and certificates. GAZEX detectors are calibrated in their own Calibrating Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation no. AP150).
