Minsk Research Institute of Radiomaterials of the National Academy of Sciences of Belarus offers consumers systems for methane (CH4) monitoring on board of a vehicle under manufacturing agreement and is looking for partners interested in distribution services agreement.

OJSC "Minsk Research Institute of Radiomaterials" of the National Academy of Sciences of Belarus manufactures systems designed to monitor the concentration of CH4 on board of a vehicle (in the engine compartment, in the places where gas cylinders are installed, in the engine liquid preheater compartment, at the vehicle gas cylinder reducers).

The system for methane (CH4) monitoring is based on optical, selective sensors with a CH4 concentration monitoring box. Gas concentration control sensors are designed to exclude water ingress with a possibility of replacing the sensing element.

The system consist of a microprocessor based monitoring box and five (5) CH4 (methane) sensors. The open architecture and the presence of two CAN interfaces make it easy to adapt to customer requirements for various applications.

The monitoring box includes:
* input for a gas concentration control LEDs test button;
* input for the control unit programming button;
* RS-232 outputs for the control unit programming connector;
* inputs for CH4 concentration sensors;
* outputs for control LEDs that signal CH4 detection in controlled places;
* output for a sound signal (buzzer) for the driver in case of an emergency state of the system;
* output for a sound signal (siren) or the relay in case of CH4 detection;
* output for the system operability LED;
* the possibility of diagnosing the serviceability of gas concentration control sensors;
* the possibility of determining the place of gas concentration using the corresponding LED;
* the possibility of diagnosing the state of the concentration system with the display of the corresponding light codes of the LEDs;
* the option to connect additional three (3) CH4 sensors.
