The configuration information is particularly important here. The “-11-01-03-00-00-01” suffix is not just a serial variation: it defines the monitor’s sensor-input configuration, range, relay arrangement, safety-barrier selection, trip-doubling selection, and approval option.
Product Introduction
The Bently Nevada 3300/16-11-01-03-00-00-01 is a 3300/16 XY/GAP Dual Vibration Monitor designed for continuous monitoring of two independent machine channels. The monitor is used with proximity-probe measurement systems to evaluate radial shaft vibration and average axial position within a Bently Nevada 3300 machinery-protection rack.
This specific configuration uses the 200 mV/mil sensor-input option and a 0–10 mil peak full-scale range, with an epoxy-sealed alarm relay. That makes the full configuration number important when replacing an installed monitor; a different 3300/16 variant may have different input scaling, relay, or approval characteristics.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
A 3300/16 fault does not automatically mean the monitor itself has failed. An incorrect probe gap, damaged extension cable, defective Proximitor, poor field termination, or incorrect monitor configuration can produce similar symptoms. The replacement should therefore be treated as part of the complete proximity measurement chain.
Typical Applications
- Steam and gas turbine machinery — radial shaft vibration and axial-position supervision.
- Compressors and pumps — continuous vibration protection on critical rotating equipment.
- Generators and motors — monitoring shaft movement within legacy machinery-protection systems.
- Legacy Bently Nevada 3300 racks — direct replacement applications where the existing monitor uses the same configuration.
Technical Pitfalls to Avoid
- Do not confuse this with a proximity probe.
The 3300/16-11-01-03-00-00-01 is the rack-mounted monitor, not the probe, extension cable, or Proximitor. Several online listings incorrectly attach this complete monitor number to sensor products. - Match the input scaling exactly.
This configuration is specified for the 200 mV/mil sensor-input option and 0–10 mil peak range. Installing a monitor with a different scaling option can result in incorrect vibration or position readings even when the hardware physically fits the rack. - Verify the relay configuration.
This unit uses the epoxy-sealed alarm relay option. Do not assume that every 3300/16 monitor has the same relay hardware; Bently Nevada offered different relay and barrier configurations. - Check the entire proximity circuit before replacing the monitor.
Confirm probe gap voltage, probe/extension-cable continuity, Proximitor output, shielding, grounding, and monitor input configuration. A bad probe loop can make a healthy 3300/16 appear defective.

Procurement Check
Before approving a Bently Nevada 3300/16-11-01-03-00-00-01, verify:
- Exact model: 3300/16
- Complete configuration: 11-01-03-00-00-01
- 7200-series proximity-system compatibility
- 200 mV/mil input option
- 0–10 mil peak full-scale range
- Epoxy-sealed alarm relay
- CSA/NRTL/C approval requirement
- No internal safety barrier
- No trip-doubling option
- Existing 3300 rack and power-supply configuration
- Probe and Proximitor model
- Existing alarm/trip setpoints
- Monitor firmware/revision where applicable
- Functional test of both channels before plant installation
- Whether the supplied unit is new surplus, used, or refurbished
Recommended procurement description:
Bently Nevada 3300/16-11-01-03-00-00-01 XY/GAP Dual Vibration Monitor, 3300 Series Machinery Protection System, Dual Channel, 7200-Series 200 mV/mil Input, 0–10 mil Peak Range, Epoxy-Sealed Alarm Relay, CSA/NRTL/C.
The important distinction is that 3300/16-11-01-03-00-00-01 is a complete, configuration-specific Bently Nevada 3300/16 monitor, not a 3300 XL proximity probe or extension cable. When sourcing a replacement, preserve the complete order number because the input scaling and relay configuration directly affect the installed machinery-protection scheme.
