Advantages of external magnetostrictive displacement transducer mounting
Sensor Cost. Externally-mounted magnetostrictive position sensors are typically made from an aluminum extrusion and die-cast end caps with gaskets, saving cost compared to all-stainless-steel welded and pressure-rated construction.
Cylinder Cost. The cylinder can be a standard type with no special machining work needed to accommodate installation of the sensor.
Cylinder Delivery Time. Since no additional machine work is needed, the cylinder manufacturer can deliver within their standard lead time for standard cylinders.
Overall Installed Length. Typically, the external sensor is mounted in parallel to the cylinder, so overall length is not increased.
Service Access. The externally-mounted sensor is easily accessible for service by simply unbolting its mounting brackets and pulling it off the equipment.
