SafEye 200

Detecting Gas

Open Path Gas Detection System | Continuous Monitoring for Combustible Hydrocarbon Gases

The SafEye 200, manufactured by Crowcon, is an open path fixed gas detection system. It is a self contained, fast response optical gas detection system which can detect combustible gases at concentrations lower than the explosion limit (LEL) over a “Line of Sight” of up to 460 ft. (140 m) long.

SafEye is the preferred system for offshore oil companies because it is immune to false alarms caused by partial blockage and extreme weather conditions (fog, rain, snow) and direct or reflected sunlight, flame and other black body radiation sources. The SafEye system can be factory calibrated to a particular gas mixture most probable to leak in a specific location. This results in the most accurate gas concentration measurement.

Crowcon SafEye 200 Gas Detectors

Tried & Tested

In an offshore installation in the North Sea, the SafEye was tested over six winter months which included weather conditions such as very dense fog, snow and rain. The gas detector remained fully operational at all times.

The SafEye range is built for reliability and continued operation under all types of extreme environmental conditions.

Typical applications include Offshore Oil & Gas Exploration Oil Rigs and FPSOs; Onshore Oil & Gas Terminals; Storage Farms and Filling Stations; Petrochemical and Chemical Industries; Power Utilities and Turbines areas;  Waste Processing and Treatment; Transportation Terminals; Automotive, Painting, Printing, Pharmaceutical Industries and many more.

SafEye 200 Gas Detector

Features

• Proven Technology Used in highly sensitive areas to detect low gas concentration levels to activate alarms measures only when specific hazardous concentration levels are exceeded. Thousands are installed on offshore platforms, FPSO’s, refineries and other onshore applications operated by British Petroleum (BP), Shell, ExxonMobil, Statoil and others.
• Cost Saving One system can replace from 5 to 20 point gas detectors in a straight line of sight, up to 460 ft. (140 m). Low cost of ownership, much lower installation cost!
• Low Maintenance High reliability, simple installation, alignment and maintenance, equipment not subject to poisoning.
• Fast Response Adjustable light source flash rate gives high sensitivity and extremely fast detection time. Also prevents detector from going into obscuration when a large cloud of gas passes through the beam.
• Standard Interface Options Standard 4-20 mA outputs or RS-485 output to allow networking (up to 64 detectors) to a central monitoring/PC system. This feature also enables easy maintenance, local and remote diagnostic tools.
• Harsh Environment Specially designed to perform under extreme conditions such as high-speed airflows, humidity and corrosive gases where point detectors may not be effective.
• T&D also stock & ship products from stock suitable for frost protection, hot water, ramp heating and roof & gutter heating

Flame, Heat, Gas Detectors & Detection Systems

Hazardous area industries including offshore oil/gas platforms and FPSOs, onshore oil refineries, processing plants, pipelines, storage farms and LPG/LNG plants all utilise or produce a wide range of hazardous flammable liquids and gases that can be detected using correctly specified flame and gas detectors.

Detecting toxic and flammable gases requires the detectors to be classified and certified according to the specific IECEx or ATEX standard – we distribute flame and fire detectors manufactured by Spectrex to operate in the harshest environmental conditions including self-contained stand-alone devices designed for direct connection to control and alarm systems or automatic fire extinguishing systems.

Our range of Hazardous Area Fire & Gas Detection System products also includes Explosion Proof Warning Systems & Hazardous Area Lighting – comprehensive range of intrinsically safe, flameproof and explosion proof alarm sounders, sirens, bells and horns, loudspeakers and beacons.
