LVDT sensor DPU

Pressure resistant cylinder displacement transducer with hole flange for installation in the cylinder base with internal sensor and core rod. The displacement transducer with a case diameter of 18mm is pressure resistant up to 200bar as standard and has a coil unit completely encapsulated in the casing with a fully symmetrical coil design according to the LVDT full bridge circuit. This achieves good linearity and high temperature stability with low temperature drift. Versions are available for 5kHz and 10kHz carrier frequency as well as for increased temperature.

Special versions with modified flange dimensions and integrated electronics according to customer specifications are possible.
