Exhaust thermocouple sensors are a key element of modern engine management. Measuring the temperature of exhaust gas can provide an important input into system algorithms to improve efficiency, reduce pollutants and extend engine life.
Exhaust Gas Sensors
Exhaust gas sensors are usually thermocouples due to the very high temperatures involved. Often 800°C or more can be achieved. Thermocouple Type K is the most common although Type J is also found in lower performance engines.

Past Exhaust Thermocouple Projects
Peak Sensors has supplied custom made exhaust temperature sensors for LGV diesel engines, sports cars, trucks and even buses. Our sensors are an integral part of systems used to reduce large vehicle exhaust pollutants which then allows them to enter low pollution areas such as London’s LEZ – Low Emmission Zone.
The exhaust thermocouple picture below includes some signal conditioning electronics to produce a linear mV output at a much higher voltage than would normally be expected of a thermocouple. This exhaust thermocouple is used with a compression fitting to form a gas seal.
