Speed sensors utilize electronic proximity switches and wiring in addition to mechanical wheels and greaseable bearing sets. Due to the mechanical nature of the speed sensor design, a catastrophic failure of a proximity switch may also require the replacement of a cog or counting wheel, in addition to a new proximity switch, to complete a repair of the speed sensor.

It is best to contact a manufacturer or local scale service company with your specific issues and further questions for their review and expert recommendation.
