Searchline Excel Linear gas detection barrier

The Searchline® Excel detector is a linear gas detection barrier consisting of an infrared transmitter and a receiver that can be located up to 200 meters away. It is particularly suitable for methane, pentane, ethane, butane, propane, ethanol, ethylene, methanol, and propylene detection in petrochemicals and large-scale storage areas.

  • Highly accurate detection of hydrocarbons over distances of up to 200 meters
  • Fast response time with a T90 fewer than 3 seconds
  • Linear 4-20 mA and Modbus RS485 multidrop output
  • Simple installation and commissioning, one system replaces multiple point devices
  • Safety approvals: ATEX, IECEx, UL, CSA, FM, and GOST
Additional information

The Searchline Excel linear gas detection barrier is installed in various demanding applications throughout the industry and is the best-selling linear barrier in the world! When hydrocarbons are present, some of the infrared radiation is absorbed by the gas, reducing the signal received that is proportional to the volume of gas in the beam.

It is immune to the sun and reduces the effects of atmospheric precipitation: rain, fog, ice, snow, or condensation. The microprocessor-controlled system is provided with a self-diagnostic and fault detection feature. The robust IP66 and IP67 rated design and wide operating temperature range of -40 to 65┬░C mean that the sensor is suitable in all weather conditions.

Linear gas detection barriers complete point fixed gas detectors such as Searchline Optima Plus or GD10P. They offer a number of significant technical advantages: larger monitoring areas and less strategic placement of the gas detectors in the monitoring area (see also the OBSERVER-i ultrasonic leak detector).

They can be found in many industrial applications. Offshore platforms, ships, chemical and petrochemical plants, gas and oil pipelines, large-scale storage areas and construction can use this ultrasonic leak detector.

Gaz detected: Butane (C4H10) - Ethanol (C2H6O) - Ethylene (C2H4) - Explosive gas - Methane (CH4) - Pentane (C5H12) - Propane (C3H8)
