The EL series linear transducers are perhaps the easiest, lowest-cost solution for achieving a robust smart cylinder with electrical position feedback. The externally-mounted EL series transducer detects the position of cylinder’s piston by sensing a magnetic field from a permanent magnet embedded in the piston itself. This method of transducer installation eliminates the need to deep drill the piston rod, providing a cost saving, while retaining the piston rod’s strength. This is of particular use for long-length cylinders, where drilling the piston rod is usually very expensive, and for double-rod steering cylinders that cannot be drilled for internally-mounted linear transducers.
