Overview

The 3300/20 Dual Thrust Position Monitor provides early detection of thrust bearing failure by continuously measuring the axial position of the shaft across two independent channels. These channels monitor the position relative to the axial clearances within the machine. The axial probes are ideally installed to observe the thrust collar directly, offering accurate measurement of the collar's position relative to the thrust bearing clearance.
