The Rosemount Analytical 975MR flame detector utilizes a multi-spectrum infrared sensor specifically designed for detecting hydrocarbon fuel and gas fires at long distances with superior reliability and the highest immunity to false alarms. The 975MR can perform in the harshest environmental conditions as either as a stand-alone unit directly connected to an alarm system or an automatic fire extinguishing system, or as part of a more complex system where many detectors and other devices are integrated through a common control unit.

The 975MR detects hydrocarbon fuel and gas fires with wide area coverage, capable of detecting a gasoline pan fire at 215 feet or diesel fuel at 150 feet in less than five seconds. Detection performance can be easily adapted to all environments, applications, and requirements by changing the detector's configuration parameters. Adjusting these parameters, as well and performing other maintenance and monitoring tasks, is possible by means of RS-485-based Modbus communication or HART communication (in models with 0-20 mA output).

Built to be extremely durable and weather-resistant, the Rosemount Analytical 975MR flame detector features heated windows for operation in harsh weather conditions, such as snow, ice, or condensation; broad operating temperature ranges from -67°F to 185°F (-55°C to 85°C); and multiple output options for maximum flexibility and compatibility.

Rosemount Analytical 975MR flame detectors help you comply with NFPA fire detection standards for industrial, storage, manufacturing, processing and other sensitive locations.
