AI-Tek tachometer transducers are self-generating units when used with speed sensors. They are designed primarily to provide an easy means of attaching a pulse-generating assembly to rotating shafts. Sensor gapping, shaft run-out, and mounting problems are eliminated.
The assembly consists of a Taper-Lock bushing which enables quick attachment to rotating shafts. The transducer employs a rotor with small perforations along its periphery; a permanently lubricated sealed bearing; an outer ring, and a reference rod which, when clamped in position, prevents the outer ring assembly from moving. The outer ring can accomodate up to three speed sensors for use in monitoring directions of rotation and speed.
