Mini capteur inductif demi pont (HBT)

Miniature gauging probe

Ideal for measurement in confined places


The Half Bridge or LVDT inductive probes technology has been known for over 100 years and enables to offer a products range covering most of the needs in dimensional control.

Materials used to manufacture our probes leads to an unqualed robustness and longevity.


The mini probe is a compact low profile transducer that is ideal for measurements in confined places such as bores. The transducer is based on a parallel spring structure that ensures that it provides excellent repeatability over a long working life, even when rotated in bores that have key slots or lubrication ports.
