Sensor Mounting
Mounting sensors with a bracket
Sometimes a sensor will not fit at the desired location on or near the bearing housing
because of an obstruction or because a suitable flat surface is not available. In these cases, it
may be necessary to use a bracket extending from the desired measurement point to an area
where the sensor can be mounted properly.
Make sure that the bracket itself does not introduce any extraneous vibrations. The bracket
must not bend or flex. Even a small amount of flexing in the bracket may result in unreliable
readings. Only a stiff bracket is able to transfer the vibration from the machine to the sensor
without adding vibration due to the natural resonance frequency of the bracket. As a general
rule, even the shortest bracket will require fabrication from 1/2-inch steel plate.
All brackets should be tested for resonance in the frequencies that the sensor will monitor. If
possible, the bracket design should be approved by your sensor or system supplier. Contact
