Overview

The Macro Sensors BBP and BBT family of pencil-type gaging probes utilize a linear ball bearing assembly precisely fitted to a hardened-and-ground, non-rotating probe shaft to minimize radial play and the effects of side loading. This results in the probes' exceptional repeatability of 0.000006 inch (0.15 μm). One end of the probe shaft is coupled to the core of a friction-free LVDT sensor, which produces an output voltage that is linearly proportional to the probe shaft position. The use of an LVDT for probe shaft displacement sensing eliminates any additional transducer errors due to friction, stiction, or mechanical hysteresis.
