When energized with a fixed AC source, the output signal is linear within a specified range over the angular displacement. Long life High reliability High accuracy Repeatable performance Robust, compact construction Custom electrical and mechanical designs available ) hall effect transducer: The Hall element is constructed from a thin sheet of conductive material with output connections perpendicular to the direction of current flow. General features of Hall effect based sensing devices are: True solid state Long life (30 billion operations in a continuing keyboard module test program) High speed operation over 100 kHz possible Operates with stationary input (zero speed) No moving parts Logic compatible input and output Broad temperature range (-40 to +1 500C) Highly repeatable operation 3) magnetostrictive transducer Magnetostrictive materials transduce or convert magnetic energy to mechanical energy and vice versa. The reciprocal effect, the change of the susceptibility [response to an applied field] of a material when subjected toa mechanical stress, is called the Villari effect. Two other effects are thus related to magnetostriction: the magnetostrictive material when subjected to a torque and the Wiedemann effect is he twisting of these materials when a helical magnetic field is applied to them. ) Orifice Plate The orifice plates are simple, cheap and can be delivered for almost any application in any material. Venturi Tube 1. Physics a device for measuring fluid flow, consisting of a tube so constricted that the pressure differential produced by fluid flowing through the constriction gives a measure of the rate of flow. 2. Also called venturi a tube with a constriction used to reduce or control fluid flow, as one in the air inlet of a carburettor
