Inductive tachometer
Commissioning Air Systems (BG 49/2015), written by Chris Parsloe and published by BSRIA in March 2015, explains how to commission ducted air distribution systems in buildings. It was originally published in 2013 and was then updated in 2015.
It states: ‘The inductive style tachometer can often be used where both the mechanical and optical instruments are not suitable. It uses an inductive probe to count events above rotating metal objects. Typical applications include shafts with slots or toothed gears where no reflection marks can be fixed.’
