دکتور شعله ضد انفجار برند MSA مدل FL4000H
(MSA Brand Multi-Spectrum Infrared Flame Detector Model FL4000H)
Description
The General Monitors FL4000H is an advanced multi-spectrum flame detector designed to provide superior false alarm immunity with the widest field of view.
The FL4000H employs a state-of-the-art multi-spectrum infrared (MSIR) sensor array with a sophisticated Neural Network Technology (NNT) system.
The FL4000H is designed to detect typical fires such as those produced by alcohol, n-heptane, gasoline, jet fuels and hydrocarbons.
In addition, the FL4000H can see through dense smoke produced by diesel, rubber, plastics, lube oil, and crude oil fires.
The NNT flame discrimination algorithm classifies the output signals from the MSIR sensor array as either fire or non-fire.
The MSIR/NNT combination is highly immune to false alarms caused by lightning, arc welding, hot objects, and other sources of radiation.
The FL4000H’s electronics are housed in a stainless-steel explosion-proof enclosure.
The detector is available with the following output configurations:
۴-۲۰ mA stepped output
Dual serial communications
HART communication
Warning, alarm and fault relays
The serial communication port(s) allows 128 units (247 using repeaters) to be linked to a host computer using Modbus RTU protocol.
The communication registers provide alarm status, fault and other information for operating, troubleshooting or programming the unit.
The COPM (Continuous Optical Path Monitoring) self-test checks optical path integrity (window cleanliness) and the detector’s electronic circuitry every two minutes.
