  • Hydraulic valve device with associated spool displacement transducer
    Patent number: 8485497
    Abstract: A hydraulic valve device includes a sensor for determining spool displacement of within the valve. The sensor includes two main subassemblies, a tube assembly and a body assembly; the tube assembly being mounted onto the valve body by the thread so that the tube together with the valve creates a closed space where oil flows; the plunger with the magnet inside, is kept in contact with the valve spool by the spring so that the magnet moves along with the spool, so does also the magnetic field created by the magnet. An integrated circuit on the printed circuit board senses the angle of magnetic field lines and generates an output signal proportional to the movement of the spool.
