EngineSens Motorsensor is presenting the product at the “Sensor + Test 2024” trade fair in Nuremberg

Viernheim, March 23, 2024.
How can you determine the residual oxygen content of exhaust gases from biogas engines and combustion systems? The company EngineSens Motorsensor GmbH from Viernheim developed an O2 monitoring system consisting of a sensor and a transmitter based on a series-proven heated lambda sensor. A main field of application for this oxygen monitoring system is the control of spark-ignited engines in biogas plants; other applications are gas burners, for example in ovens, and industrial flue gases.

Current wide-range lambda probes can measure the oxygen content in exhaust gas mixtures from lambda 0.8 up to air across a wide range. This requires oxygen pumping technology based on a multi-layer planar sensor structure. During continuous operation, multi-layer pumped sensors tend to delaminate and fail prematurely. EngineSens uses a proven step-response lambda sensor with a simple structure. This four-wire heated probe, in conjunction with the specially developed transmitter, can still cover the lambda range 0.95…1.3 with high resolution. The transmitter can be linked to any PLC control. An analogue 0…20 mA signal is output, which can easily be transported over long distances. The attenuation that occurs in long cables hinders the reception of digital bus signals. That's why the manufacturer decided to use this analogue output. It is also possible to read the signal with a multimeter. The transmitter is powered with 12-24 V DC. The user only needs to connect two independent 12-24 V DC power supplies and an analogue input card with 4...20 mA to the PLC control. The first power supply is for the sensor, the second for the output current. The transmitter is clipsed onto a hat profile mounting rail and the probe is screwed into an M18x1.5 thread.

The company EngineSens Motorsensor GmbH, based in Viernheim in southern Hesse, manufactures temperature sensors for operating temperature ranges up to 1,100°C and sells exhaust gas sensors and analysis kits for catalytic converters and engines. Customer-specific sensors are manufactured and tested in-house in quantities ranging from one to several thousand pieces. We will be exhibiting at the “Sensor + Test 2024” trade fair in Nuremberg from June 11th to 13th, 2024 in Hall 1-472.
