OLCT100 Gas Detector

Technical Description – OLCT100 Gas Detector

Designed for the detection of explosive gases, toxic gases or oxygen, this gas detector comes with a Wheatstone bridge output (OLC 100) or 4-20mA output (OLCT 100).​ Whatever your application Teledyne Gas and Flame Detection offers a solution: MEMS, catalytic, electrochemical, semiconductor, or poison control version. ATEX approved, these detectors are available in explosion safe or intrinsically safe versions.

In addition to this range the OLC/OLCT 100 offers an infrared sensor​, which allows it to be used in more severe environmental conditions, where the presence of poisons could harm the use of a catalytic sensor.

SIL 2 certified according to EN 50402, the 100 series is very safe. As an example, the Probability of Failure on Demand (PFD) of combustible versions is 1 out of 418 for the catalytic version and 1 out of 2857 for the infrared version.

A Closer Look

The OLC/OLCT 100 range of fixed detectors has been designed for detection of combustible gases, toxic gases, or oxygen. Available in explosion-proof or intrinsically safe versions, the OLCT 100 is suitable for detection of all gases in IEC Ex zones. The OLCT 100 is available in a stainless-steel version, offering increased resistance to corrosive elements (ideal for marine, wastewater treatment plants, food processing activities, etc). This stainless steel intrinsically safe version is certified for use in zones 0 (gas) and 20 (dust), whereas all other versions of the OLCT 100 are certified for use in zones 1 (gas) and 21 (dust).
