Detection of Pipe Elbows

A very simple and efficient way to ensure the correct position of a pipe elbow is to attach an actuator at the elbow and detect its position with an inductive sensor for each possible elbow position.

The greatest danger for these sensors is the mechanical damage caused by the operator during mounting. This risk significantly increases over time as the seals wear, and thus the actuator is moving closer to the sensor. 

Due to their especially large switching distance, Uprox+ sensors provide an extra safety distance that avoids sensing problems.
