LVDT sensor DOE
Pressure resistant cylinder displacement transducer with hole flange and integrated electronics for installation in the cylinder base with internal sensor and core rod. The displacement transducer with a Case diameter of 20mm is Pressure resistant up to 320bar as standard and has a coil unit completely encapsulated in the casing with fully symmetrical coil construction according to LVDT full bridge circuit. This provides good linearity and high temperature stability with low temperature drift. The electronics are supplied with ± 15V and provide a ± 10V Output signal.
Special versions with modified flange dimensions and in other pressure classes are possible according to customer requirements.
