LVDT sensor DGO

Pressure resistant cylinder displacement transducer with threaded connection for installation in the cylinder base using M30 x 2 thread for internal sensor. The displacement transducer with a case diameter of 20mm is pressure resistant up to 450bar as standard and has a coil unit completely encapsulated in the casing with fully symmetrical coil construction according to LVDT full bridge circuit. This results in good linearity and high temperature stability with low temperature drift.

Special versions with modified dimensional specifications, adapted electrical data and in other pressure classes according to customer requirements are possible.
