The range of Crowcon open path gas detectors are fixed gas detectors which use infra-red technology for the quick detection of combustible gases and vapours over a line-of-sight up to 200m long.

The Crowcon open path gas detector range uses a well proven technology, known as “Xenon Flash”, which is unaffected by unpredictable weather (including sunlight), flame and radiation. False alarms are kept to a minimum even when the gas detector is partially blocked.

Crowcon Open Path Gas Detectors

Crowcon Open Path Gas Detectors – infra-red gas detection system based on well proven technology

➡ Crowcon open path gas detectors are part of the SafEye range which comprises of the following devices

SafEye Quasar 900

Quasar 900 is totally immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning. The high power Xenon lamp will compensate for changing weather conditions, including rain, fog, mist or snow.

Optical lenses are thermostatically heated in order to prevent the formation of ice and build up of snow even under severe weather conditions. It also eliminates the build up of condensation on the lenses. Safeye Quasar 900 is designed to SIL2 (IEC61508), equipped with heated optics and tolerates a temperature range between -67°F and + 149ºF (-55ºC to + 65ºC).

An internal data-logger keeps a detailed record of the previous 100 events and the minimum detectable level is 0.15 LEL.m.

Each detector is supplied with methane, propane and ethylene calibration as standard which can be selected in the field by the user. One person can easily align and commission the system without the need for any special training. After an initial adjustment by eye, a telescope is fitted allowing fine adjustment to optimised the signal strength.

SafEye Xenon 700

One-Person Commissioning and Installation – One person can simply and easily align and commission SafEye with separate horizontal and vertical adjustments.

Fast Response – Direct reading, high sensitivity and fast response (3 sec) ensures instant action and maximum safety.

Harsh Environment – Well-proven in harsh environments (rain, snow, fog, hot and humid weather), up to 90% beam blockage, an excellent operational record in many installations worldwide. – Heated Optics on the source and detector increase the temperature of the optical surface to reduce icing, condensation and snow. – Resilient and excellent performance withstanding extreme vibrations, displacement and shock. – Solar blind and immune to false alarms from industrial environments

Detects a Wide Range of Gases Reliable detection of gas leaks including a wide range of gaseous hydrocarbons, such as: Alkanes, Alkenes (C1-C8), Alcohols, LNG, LPG, Ethylene, etc.

Cost Effective – Less units needed for protection compared with point type detection. One system can replace from 5 to 20 point gas detectors. Low cost of ownership, much lower installation cost

Large Misalignment Tolerance – Provides relatively wide angle of view, better than 1˚, to withstand vibration, mechanical shock and displacements.

Standard Interface Options Standard – 4-20 mA output with a new mode (3 mA) “Maintenance call” or RS-485, Modbus compatible output to allow networking (up to 256 detectors) to a central monitoring / PC system. This feature also enables easy maintenance, local and remote diagnostic tools.

No Poisoning Effect Electro-optical system, not affected by chemicals.

Rugged Structure Stainless steel 316L, IP66/67, Zone 1 ready design

SafEye 200

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!

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.

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.

Low Maintenance – High reliability, simple installation, alignment and maintenance, equipment not subject to poisoning.

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.

Duct Mounted SafEye Fixed Gas Detector

  • High Sensitivity – Alarm up to 0.5 LEL.m. 5 times more sensitive than the normal Open Path equipment
  • Fast Response – Fast response time of 2 seconds (300 series) and ultra fast response of 1 second (200 series). 5 to 10 times faster than the commonly used Open Path detector and 20-50 times faster than the Point Detector.
  • Low Maintenance – High reliability, simple installation, alignment and maintenance, equipment not subject to poisoning.
  • Proven Technology – Used in air ducts on FPSO’s and offshore rigs for British Petroleum (BP), Shell and ABB Lummus for turbines, air intakes, etc.
  • Harsh Environment – Specially designed to perform under extreme conditions such as high-speed airflows, high temperatures (up to 158˚F (70˚C)), humidity and corrosive gases, where point detectors may not be effective.
  • 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.

Crowcon Open Path Fixed Gas Detector Systems

Crowcon Open Path Gas Detector Bump Testing & Calibration

Routine bump testing is recommended for the range of Crowcon fixed gas detectors prior to each use. Bump testing is a brief application of a gas to the sensor to invoke a prescribed reaction, ensuring the gas detector reacts as expected.

Bump testing provides a quick, easy and direct method of verifying gas detectors are performing as required and takes a lot less time than ‘zeroing’ the device.

The bump test is widely accepted as a suitable method of testing gas detection equipment.
