false information will be generated. Side view can be avoided by proper gapping of the probe or by
removing conductive material by counterboring.

Brackets or other structural members used to mount probes must be rigid. When using a mounting
bracket, it should be field checked for resonant frequency. The resonant frequency should be at least
ten times machine running speed. Brackets must support the probe in a position perpendicular to the
observed surface. The probe axis can vary 15 degrees from perpendicular without affecting the
performance of the transducer system.
Probes may be mounted through existing machine hardware such as the bearing cover of a machine
case. Many times it is advantageous to use an external mounting adapter, allowing the probes to be
removed and replaced, or gapped again without taking the machine apart. For more information on
mounting brackets and adapters, contact your nearest Bently Nevada office for information on
transducer accessories.
