Displacement sensors
General information
A fiber optic displacement sensor is used to measure travel range between where an object is and a reference position. A displacement sensor is used for all kinds of dimension measurements, for example and object's thickness, height, and width in addition to travel range.
The sensor on the left is a spring-loaded linear displacement sensor. This displacement sensor has a range of 30mm and can be adjusted at installation within the 30 mm range.
The displacement sensor has an integrated temperature sensor which is used for temperature compensation during measurement.
A few application examples:
-
Crack monitoring
-
Settlement measurement
-
Dilatations
-
Borehole extensometer
