Rosemount™ 975MR Multi-spectrum Infrared Flame Detector to detect the absorption of certain wavelengths of light wavelengths




It said that fire detectors, also known as optical sensors flame detector in the protected area. Each fire emits visible light as well as infrared invisible (IR) and ultraviolet (UV) rays. UVIR UV flame detector or sensor in this radiation is invisible to distinguish between real fire and a source for the detection of clear radiation.

Flame detector can be connected to the fire alarm control system, or it can serve as a stand-alone device exists to alert staff or shut down the equipment in case of fire. The flame detection devices are designed to detect the absorption of certain wavelengths of light wavelengths. It allows them to distinguish between the fire and sources of false alarm.

Rosemount™ 975MR Multi-spectrum Infrared Flame Detector

Rosemount™ 975MR Multi-spectrum Infrared Flame Detector analyze of multi-spectral signals accurately through the use of three radiation sensor under a separate red. Moreover, 975 MR detects fuel and gas fires at long distances. For example, these products detect 1 FT2 (0.1m2) pan gasoline fire at 215 ft (65 m) in less than 5 seconds. 975MR high immunity to false alarms and increased diversity also provides universal coverage.

Rosemount™ 975MR Multi-spectrum Infrared Flame Detector fire detection devices use patented digital signal processing to analyze the spectral characteristics and dynamic Infra-red. This is measured to determine the fire All detectors include a series of 975 visual window heated to improve performance in the ice. Event with exceptional sensitivity and extreme immunity to false alarms, detection performance can be easily adapted to all environments, applications, and requirements. Those can be done by changing the configuration parameters to detect.


The features and benefits of Rosemount™ 975MR Multi-spectrum Infrared Flame Detector

Rosemount™ 975MR Multi-spectrum Infrared Flame Detector has specific features are stated as follows:

1. Multi spectrum design : for the detection and high immunity after false alarm
2. Heated window : to work in extreme condition.
3. Sensitivity option : to ensure no crossover detection area
4. Automatic and manual built-in testing (BIT) : to ensure reliable operation


In addition, this Rosemount™ 975MR Multi-spectrum Infrared Flame Detector also enable user to get maximum detection target as with specification as below:

1. Multiple output maximum degree options:
