OLCT100 Fixed Gas Detector

The SIL2 certified OLCT100 fixed gas detector is available in ATEX versions for explosive gas or intrinsically safe (IS) for toxic gases. With nearly 150 gases listed, this 4-20 mA linear output gas detector is suitable for explosive gases detections (hydrocarbons, solvents, alcohols), toxic, asphyxiating, and refrigerant leaks (freons, HFO, CFC, HFC).

  • Fixed gas detector for explosive gases, hydrocarbons, solvents, toxic gases, freons, VOCs, CO2
  • ATEX & SIL 2 certification for catalytic and infrared versions
  • Epoxy-painted aluminium housing (316L stainless steel optional)
  • Wheatstone bridge or linear 4-20 mA outputs
  • Power supply ranges from 15.5 to 32 VDC depending on the application
Additional information

The wide range of sensor technology available for the OLCT100 fixed gas detector allows this instrument to detect a wide range of gases. It is suitable as a Wheatstone bridge version (OLC) for explosive gases as 4-20 mA analog transmitter version (OLCT) for explosive, toxic, refrigerant, and asphyxiating gases.

It is a blind gas detector (without display) to be connected to the MX16, MX32, and MX43 control units for the Wheatstone bridge and analog versions or any other gas detection unit for the 4-20 mA transmitter versions.

Many ATEX accessories are available for the OLCT100 to increase the sensor response time or to install the sensor in optimal conditions.

The OLCT100 fixed gas detector is available in 5 different versions:

OLC100-XP: Wheatstone bridge output version with a catalytic cell for the detection of explosive gases (0-100% LEL).

OLCT100-XP: Explosion-proof version with catalytic, electrochemical, or semiconductor cell to explosive gases, some toxic gases (CO, H2S, NH3), and oxygen detections.

OLCT100-IS: Highly reliable version with an electrochemical cell for the detection of toxic gases.

OLCT100-XPIR: Explosion-proof version equipped with an infrared sensor for the detection of certain refrigerant gases (HFO1234yf, HFO1234ze, R134a, R407a, R407f, R449a), SF6 and CO2.

OLCT100-XPHT : High-temperature explosion-proof version for detection of explosive gases up to 200 °C.

For gas detector calibration, periodic checks or gas tests, we offer a wide range of calibration gases in disposable cylinders that meet the ISO6142 standard.
