Abstract
A method and device for measuring the soot load in the exhaust gas systems of diesel engines using a sensor which is mounted downstream of a particulate filter and comprises a sensor element, to measure the operability of the particulate filter. According to the method, the soot load of the sensor element is measured resistively or capacitively using electrodes. The measuring voltage of the sensor element is controlled depending on at least one actual operating parameter of the diesel engine.
Claims8
An infrared radiator arrangement for a gas analysis device, comprising:
- a radiator housing;
- a plate-shaped ceramic body arranged in an interior of the radiator housing;
- a structured heat resistant layer applied on the plate-shaped ceramic body;
- a radiation-transmissive window arranged on one side of the radiator housing to close off the interior of the radiator housing;
- wherein the plate-shaped ceramic body comprises an equilateral triangular plate mounted on an internal circumference of the radiator housing at triangular tips of the equilateral triangular plate.
