BENTLY NEVADA 3300/20-13-03-01-00-00

Bently Nevada 3300/20-13-03-01-00-00 is a Dual Thrust Position Monitor designed to safeguard machinery from thrust bearing problems. It continuously tracks the axial position of a shaft relative to its bearing clearances using two independent channels. This allows for early detection of excessive movement that could signal bearing wear or impending failure.

3300/20-13-03-01-00-00 is a Dual Thrust Position Monitor manufactured and designed by Bently Nevada as part of the 3300 Series used for machinery vibration monitoring systems. The 3300/20 Dual Thrust Position Monitor provides early warning of thrust bearing failure. It continuously measures and monitors two independent channels of shaft axial position relative to the axial clearances within the machine. Ideally, the axial probes are installed to observe the thrust collar directly, so the measurement represents the position of the collar relative to the thrust bearing clearance. Because thrust measurements are made by observing the gap voltage of the proximity probe used as an input, a transducer failure (gap out of range) can be interpreted by the monitor as thrust position movement and result in a false thrust alarm. For this reason, Bently Nevada LLC. does not recommend the use of a single probe for thrust position applications. Instead, these applications should use two proximity probes observing the same collar or shaft and configure the monitor as AND voting whereby both transducers must simultaneously reach or exceed their alarm setpoints for the monitors alarm relays to actuate.
