Fluid pressure cylinder movement time sensor

A fluid pressure cylinder movement time sensor is equipped with a single magnetic sensor (12). A point in time at which a magnetic flux density detected by the magnetic sensor exceeds or falls below a first threshold value is defined as one of a starting point or an end point, and a point in time at...

Beschreibung
Zusammenfassung:	A fluid pressure cylinder movement time sensor is equipped with a single magnetic sensor (12). A point in time at which a magnetic flux density detected by the magnetic sensor exceeds or falls below a first threshold value is defined as one of a starting point or an end point, and a point in time at which the magnetic flux density detected by the magnetic sensor exceeds or falls below a second threshold value is defined as another one of the starting point or the end point.
