Bently Nevada 3300/65-14-01-00-00-01-00 Dual Probe Monitor

Product Overview

The Bently Nevada 3300/65-14-01-00-00-01-00 is a Dual Probe Monitor designed for the 3300 machinery monitoring system. It combines the relative shaft-vibration signal from a proximity transducer with the casing-vibration signal from a velocity Seismoprobe mounted on the same measurement axis. These two signals are processed to produce a shaft absolute-vibration measurement. This configuration has a 0–500 µm full-scale range and accepts a 3300 or 7200 Proximitor input. It is supplied for use with a Seismoprobe and an epoxy-sealed alarm relay. The monitor provides relative shaft vibration, bearing-housing vibration, shaft absolute vibration and average shaft radial position information. The 3300/65 is particularly suited to large rotating machines with fluid-film bearings, where a noticeable portion of shaft vibration is transmitted through the bearing structure to the casing.

Frequently Asked Questions

1. What measurements does the 3300/65-14-01-00-00-01-00 provide?
It provides shaft relative vibration, bearing-housing vibration, shaft absolute vibration and average shaft radial position based on the proximity probe gap signal.

2. What is the measurement range of this configuration?
The “14” option specifies a full-scale vibration range of 0–500 µm.

3. Which proximity transducers can be connected?
The “01” relative-transducer option supports Bently Nevada 3300 or 7200 Proximitor systems. The complete probe, extension cable and Proximitor configuration must match the installed monitoring system.

4. Which seismic transducer is used with this model?
The “01” seismic-transducer and relay option is configured for a velocity Seismoprobe and includes an epoxy-sealed alarm relay.
