Our solutions

We design and manufacture sensors for industrial, diesel, dual fuel and gas engines, for use in the marine, energy, rail, mining and nuclear industries.

We provide a wide range of sensors, particularly for harsh environments, such as ones with very high temperatures or high levels of vibration for exhausts, combustion chambers and turbo-chargers. Our sensors can be immersed in hot oils for bearing temperatures and the vast majority of our products are IACS, ATEX, or CSA certified.

We have extended our range to include impact sensors and have developed a series of smart sensors, for temperature with CAN signal J1939, infrared for measuring gas quality and even a wireless sensor for measuring connecting rod head temperature.

Niris gas sensor

Real-time measurements of natural gas fuel quality to ensure your engine performs optimally

Niris gas sensors enable more efficient fuel consumption by allowing them to be tuned more closely to the knock limit, reducing the risk of engine shut-down.

The software is fully upgradable by CAN bus communication without the sensor needing to be dismantled.

Can sensors serie

Designed for diesel and gas engine applications

Modern engines are increasingly complex, regulatory requirements in terms of emissions, safety as well as the optimization of power performance and consumption expected from operators require the use of numerous sensors and actuators thus multiplying the number of wires of the wiring harness.

To address this problem, CMR has developed a range of intelligent sensors with data transmission via CANJ1939, which allow the quantity of wires to be reduced by 10 in the case of a 20-cylinder engine, for example.
This technology actually makes it possible to connect up to 255 sensors on a CAN loop requiring only 4 wires (2 for the power supply and 2 for the CAN bus). Using the CAN output greatly simplifies motor wiring, data can easily be sampled and used by the motor controller, including real-time diagnostics. The reliability of this sensor is proven by the history and reputation of CMR, as a global supplier to major engine manufacturers for over 60 years.

The sensor is designed especially for harsh environments such as temperatures on diesel and gas engines. The CAN signal J1939 allows direct connection to the engine ECU or to any monitoring system operating under CAN.
