Our already very extensive sensor programme has once again been expanded with a new family member. This time it is EGT-sensors (exhaust gas temperature sensors) that complement our programme of now 13 different sensor types and more than 5,000 references. So far, more than 300 references in EGT-sensors are in stock and can be ordered via the usual channels.
The EGT-sensor (Exhaust Gas Temperature Sensor) is depending on the engine type used at up to 7 different positions in the exhaust system - for example the exhaust manifold, EGR-cooler, turbocharger, front catalytic converter (DOC), diesel particulate filter (DPF) and rear catalytic converter (SCR). Combined with information from other engine/exhaust system sensors, the vehicle's engine control (ECU) uses the temperature measurements to for example determine when a regeneration process of the diesel particulate filter should be initiated.
System design of EGT-sensor
There are two types of exhaust gas temperature sensors - one with PTC-sensor element (Positive Temperature Coefficient) and the other NTC-sensor element (Negative Temperature Coefficient). In both types, the temperature is measured in relation to the electrical resistance, which is measured and registered by the motor control unit (ECU) of the vehicle.

The more than 300 references that we have included in the programme so far are characterized by:
• OE quality
• Closed stainless steel casing
• Mineral insulated cable for heat separation
• Teflon insulated cables that are oil, fuel and water resistant
• Twisted cablesfor greater flexibility
• In addition, 100% function tests are performed
Our sensor programme today includes the following product groups and is continuously expanded:
• ABS-sensors
• Brake wear indicators
• Differential pressure sensors DPS
• EGR-valves
• Throttlebodies
• Camshaft position sensors
• Crankshaft position sensor
• Oxygen sensors
• Air flow meters
• MAP-sensors
• Parking sensors
• Ignition
• Water temperature sensors
