Torque motor
signal converter, in which an electromagnetic armature moves in the magnetic field of two permanent magnets ( Figure T 14 ). If one side is activated, the magnet rotates in this field, which is transferred
SP
hydraulic fluid may be chosen freely, since these can be used from any flow direction. The switching magnets are designed for 12 or 24 V DC. The standard version's plug-in valves come with AMP superseal connectors
Solenoid
signal converters used to actuate valves are often referred to as solenoids. These are not permanent magnets, but are electromagnets. An electrical input signal (voltage or current) generates, via the magnetic
Velocity measurement
measurement is provided by using an inductive sensor. It comprises a coil around which there are rod magnets (Figure G 9 c) . If magnetic material is moved past a pole on the magnet, there is a change in the
