ETaPS – Electrical Tailpipe PM Sensor

Dekati’s ETaPS, Electrical Tailpipe PM Sensor is a unique device for diesel and gasoline vehicle PM emission measurements. It is installed directly into the vehicle tailpipe, and therefore it does not need any complex and expensive dilution systems usually required for PM measurements.

ETaPS detects the amount of particles going through the sensor head. Particles are not collected and that reduces the need for maintenance. Also the principle is such that the device works well even when it becomes dirty in the tailpipe conditions.

Low power consumption (12-18V, 250mA), lack of dilution equipment and basically maintenance-free operation makes this an ideal device for on-board tests as well as for I/M (Inspection and maintenance) type of measurements. Good sensitivity and very repeatable measurement allows also after treatment device measurements, engine development and quality control measurements.
