Designed For The Detection Of Explosive Gases, Toxic Gases Or Oxygen.
SKU
OLCT100
The Oldham OLCT 100 Fixed Gas Detector has been designed for the detection of explosive gases, toxic gases or oxygne with 4-20mA output.
Available in explosion-proof or intrinsically safe versions, the OLC(T) 100 is suitable for detection of all gases in ATEX zones.
Regardless of your application, Air-Met's range of Oldham Fixed Gas Detectors 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 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. With a 3-year warranty on the sensor and electronics, the OLCT 100 XP-IR will provide reliability and extended lifetime.
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.
