Pressure resistant cylinder displacement transducer with threaded connection for installation in the cylinder base using M18 x 1.5 thread for internal sensor. The displacement transducer with a Case diameter of 15mm is pressure resistant up to 300 bar 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 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.
