1.1 Overview
The SharpEye 40/40I is a flame detector that utilizes improved IR3
technology to provide state-of-the-art fire protection. The 40/40I uses
patented digital signal processing to analyze the spectral and dynamic
characteristics of the measured infrared radiation, to identify fire events
with exceptional sensitivity and extreme immunity to false alarms.
All 40/40 series detectors include a heated optical window for improved
performance in ice, snow, and condensation conditions.
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 (in models with 0
– 20mA
output).
The detector enclosure is ATEX certified Exd flameproof with an integral,
segregated, rear, Exe terminal compartment (avoiding exposure of the
sensors and electronics to the surrounding environment). Hence the
combined approval:
