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: 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.
