Task:
The speed of the suction fan, diesel engine and hydrostatic drive of a street sweeping vehicle are to be measured and used as inputs to the control system. The control system monitors the speed of each device in relation to each other.

Solution:
The speeds are measured and passed on by means of three stainless steel SDP2 differential hall-effect sensors. Three identical sensors are used to ensure high availability and simplify handling in the event of maintenance. The sensor is equipped with a TPE cable and a Sure-Seal plug (ITT Cannon) for rough environments. A high resistance to media is achieved in this way.
