MOBILE HYDRAULIC SOLUTIONS Gefran uses one of the most widespread and proven existing measurement principles, the so-called “Wheatstone Bridge”. According to this principle’s basis, a number of different technologies may be applied to design the sensitive element. For example, Gefran has chosen the thick film technology on the KH, KHC, KM and KMC models. THICK FILM ON STEEL TECHNOLOGY Usingthe “screen printing process” technique, the insulating layers (dielectric), the conductive layer (cermet) and the resistive layer are deposited on the steel membrane to create the “Wheatstone bridge”. The...

BEYOND TECHNOLOGY POSITION TRANSDUCERS Linear and angular position transducers detect the position of mechanical parts in motion. Real-time position detection makes it possible to reduce machine cycle times and to intercept points for actuation of other servo-mechanisms in the stroke. For example by introducing acceleration and deceleration ramps, Gefran has adopted a number of technologies for transduction of position measurement: • POTENTIOMETRIC of military origin, in which the resistive and collector track are electrically connected by means of contact brushes mounted on the spool. • MAGNETOSTRICTIVE...
