3M Gas & Flame Detection’s toxic and combustible gas detectors have been specifically designed for to provide optimum accuracy, safety and reliability during deployment in chemical facilities.
This combustible gas detector comes with a Wheatstone bridge output (OLC 100) or 4mA-20mA output (OLCT 100). Whatever your application, 3M Gas & Flame Detection offers a solution: catalytic, electrochemical, semiconductor, or poison control versions.
These ATEX-approved detectors are available in explosion-safe or intrinsically safe variants.
In addition to this range, the OLC / OLCT 100 offers an infrared (IR) 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.
With a three-year warranty on the sensor and electronics, the OLCT 100 XP-IR will provide reliability and extended lifetime.
With this new line of detectors, 3M Gas & Flame Detection broadens its product range with products that combine reliability, durability and ease of use.
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 one out of 418 for the catalytic version and one out of 2857 for the infrared version.
