LVDT sensor DT

Robust inductive displacement transducer for numerous industrial applications in production, testing, quality assurance. The probe sensor with a case diameter of 20mm has a coil unit with fully symmetrical coil design according to the LVDT differential transformer principle / full bridge circuit. The precision bearing enables high load cycles with very low wear.

Special designs according to customer specifications are possible.
