Smith Systems, Inc. passive speed sensors (Magna-Tran ®)convert mechanical motion to an A/C voltage without the need of a power supply. These self-contained magnetic sensors produce a magnetic field which, when in the proximity of ferrous objects in motion, generate a voltage. The frequency of this voltage is directly proportional to the speed of the object in motion. (read more)
