Wheel Pulse Transducer Type CWPTA
3. Product Overview
3.1 General Description
WPT sensors are universally adaptable sensors for the
acquisition of vehicle wheel speed. The sensors deliver
1 000 pulses per rotation (standard, other values on
request).
WPT sensors are ultra-compact and extremely light in
weight. For maximum flexibility, the incremental transducer unit of the WPT can be exchanged quickly and
easily.
Output signals generated by the WPT sensors provide the
basis from which wheel rotation speed, acceleration,
distance, and speed are calculated (measurements of this
kind are afflicted with slip and dependent of the dynamic
wheel circumference.
