Emerson Rosemount 975 - Introduction; Product Overview; Models

1 Introduction
1.1 Product overview
The Rosemount 975 series is based on proven technologies, including triple infrared (IR3)
and ultraviolet infrared (UV/IR). The Rosemount 975 series provides the fastest response to
fire, longest distance detection, and revolutionary UV/IR technology, coupled with superior
immunity to false alarms, functioning in harsh conditions with unparalleled reliability and
durability.
The series is suited to meet the challenges of wide range of industrial and commercial
applications with long distance and fast response detection, providing superior protection
of high value property and personnel to keep an eye on your safety.
Detection performance can be easily adapted to all environments, applications, and
requirements, by changing the detector’s configuration parameters. Adjusting these
parameters, as well as performing other maintenance and monitoring tasks, is possible
by means of RS-485-based Modbus
®
communication or HART
®
communication.
1.2 Models
The Rosemount 975 Flame Detectors are electro-optical devices designed to identify fire
events, enabling alarm activation. The detectors are intended for indoor or outdoor use
and can be used stand alone or connected to an alarm or automatic extinguishing system.
The Rosemount 975 series comprises the following detectors:
Rosemount 975MR
The Rosemount 975MR Ultra Fast Multi-spectrum Triple Infrared (IR3) Flame Detector
provides superior, longest distance detection of hydrocarbon fires at up to 300 ft (90
m), exceptional ultra-fast detection in under 50 msec, and unparalleled reliability. The
Rosemount 975MR is based on proven IR3 technology, ensuring highest sensitivity with
best immunity to false alarms.
Rosemount 975HR
The Rosemount 975HR Multi-Spectrum IR Flame Detector provides superior, longest
distance detection of hydrogen (at up to 165 ft [50 m]) and hydrocarbon (at up to 300 ft
[90 m]) fires, exceptional ultra-fast detection in under 50 msec, and unparalleled reliability.
The Rosemount 975HR is designed to deal with the challenges of invisible fires based on
proven triple IR (IR3) technology, ensuring highest sensitivity with best immunity to false
alarms.
Rosemount 975UF
The Rosemount 975UF Ultra Fast UV/IR Flame Detector can detect fire in under 20 msec
and features a unique dual sensor with selectable UV and IR channels that can be used
separately or combined. The detector is designed to detect a range of fires, such as
hydrocarbon-based fuel and gas, hydroxyl, hydrogen, metal, and inorganic.
Rosemount 975UR
The Rosemount 975UR Ultra Fast UV/IR Flame Detector can detect fire in under 20 msec
and features a unique dual sensor with selectable UV and IR channels that can be used
separately or combined. The detector is designed to detect hydrocarbon-based fuel and
gas fires.
