TecSonics™ Bearing Monitoring Sytem

Six precision, ultrasonic sensors are mounted in both thrust and radical bearings at strategic points, becoming part of the bearing surface.

A signal from the instrument excites a piezoelectric crystal in each sensor which emits a high-frequency sound wave which echoes off the face of the sensor, re-exciting the crystal which sends a signal back to the instrument.

The instrument translates the echo time into distance (sensor length) and bearing condition. A multiple array of sensors provides the safety of redundancy and accuracy of +/- .0002". Measurements are compared to the baseline readings to determine if bearing wear has occurred.
