Additional information

Especially engineered for the monitoring and the detection of the most commonly used gases in the  light industry and the tertiary sector (laboratory, hospital, wastewater treatment, refrigerated rooms, boiler rooms…), the OLCT 10N fixed gas detector has been designed to be digitally linked to the MX 43 gas detection controller only. Reliable and featuring a fast response time, the OLCT 10N fixed gas detector can be linked up to 32 detectors on the same digital line, which reduces wiring costs.


The OLCT 10N is a reliable digital detector transmitter with fast response time designed to detect oxygen (O2) and toxic gases (CO2, H2S, NH3, NO, NO2) as well as combustible gases such as methane, propane, butane and hydrogen. This detectors uses electrochemical, catalytic or infrared sensors depending on the target gases and the applications.


Made of ABS (Acrylonitrile butadiene styrene) material schock and UV resistant and ATEX 3 GD approved, this detector can be used for applications in ATEX zones 2 and 22 and is waterproof and immune to dust (IP65). The OLCT 10N is also compliant with electromagnetic compatibility according to EN50270 standard.


The OLCT 10N is a digital fixed gas detector without display with automatic non-intrusive calibration which does not require the housing opening. Manual calibration is possible by opening the OLCT 10N. After a sensor replacement, both manual and automatic calibrations have yet to be conducted. It features two M16 cable gland inputs and a digital signal output RS485 Modbus proprietary.


Depending on the density of the target gas or the application, the detector shall be mounted at the ground level, or on the ceiling at the same height as the airflow, or near to the air extraction ducts.


In option, this digital detector transmitter can be provided with shock guard protector and/or a calibration tool kit.
