MH-Series Flexible MH Magnetostrictive Linear Position Sensor
Brand: Temposonics an Amphenol CompanyDesigned for use with hydraulic cylinders in mobile applications, the externally threaded Flexible MH sensor features an innovative two-part design.
This design allows users to separate the flexible sensing element and electronics from the housing without opening the hydraulic system.
While it is manageable to install and remove hydraulic cylinder sensors at a manufacturing facility, it can be extremely challenging in the field.
Trained service technicians can remove and replace the internal components with just 200 mm of clearance regardless of stroke length and without breaking the hydraulic seal.
This serviceability means decreased downtime and disruption, providing increased productivity. Replacement units ship as coiled rings to ease handling and reduce shipping costs.
