  • Free moving magnetic core
  • High pressure operation
  • High repetability
  • Very high reliability
  • Suitable for harsh environment applications
The PJs series are LVDT-s designed for applications of measurement in high pressure hydraulic cylinders (piston displacements). PRINCIPLE OF OPERATION The LVDT is a cylindrical electromechanical device consisting of one primary winding, two secondary windings and a moveable core . When the primary is powered and the core moved, the output from the secondaries is proportional to and in phase with the core movement. The construction gives a possibility to insert the core connecting rod from the any side of the ransducer.
