Selection Criteria: Choose the 95mm length when mounting depth exceeds 80mm or when thermal barriers require extended reach. For applications with limited radial clearance below 15mm, consider the 8mm diameter variant. Verify target material is ferrous (magnetic permeability >100) and surface finish is better than 3.2 Ra for optimal linearity.
System Compatibility: This proximity sensor interfaces with Bently Nevada 3300 XL proximitor sensors (models 330180, 330780) and 3500 rack-based monitors (models 3500/40M, 3500/42M). Digital output options available through 3500/60 temperature monitors when paired with RTD assemblies.
Remote Monitoring: When connected to 3500 rack systems with Ethernet communication modules, vibration data streams to SCADA platforms via Modbus TCP or OPC protocols. Cloud-based analytics platforms (System 1 Evolution, Orbit 60) enable remote diagnostics and fleet-wide benchmarking.
Customization Options: Extended cable lengths (10m, 15m, 20m) available for installations with remote junction boxes. Special temperature ratings (-55°C to +150°C) and explosion-proof certifications (ATEX, IECEx) can be specified for hazardous area applications.
Standard Lead Time: 3-5 business days for in-stock units with factory calibration certificates. Express shipping available for critical outage support.
Custom Configurations: 10-15 business days for non-standard cable lengths or special certifications requiring additional testing and documentation.
Warranty Coverage: Comprehensive 12-month warranty covering manufacturing defects, calibration drift exceeding ±2%, and component failures under rated operating conditions. Warranty excludes mechanical damage from improper installation or operation beyond specified limits.

Documentation Package: Each shipment includes calibration certificate with NIST-traceable data, installation manual with torque specifications, dimensional drawings in DWG/PDF formats, and material certifications (MTR) upon request.
What gap voltage should I target during installation of this proximity sensor?
Set the initial gap to achieve -9.0V to -10.0V output when using Bently Nevada 330180 or 330780 proximitors. This corresponds to approximately 1.0mm to 1.2mm physical clearance from a 4140 steel shaft. Use a feeler gauge for precise positioning before tightening the lock nut to 15-18 Nm torque.
Can this sensor monitor aluminum or titanium shafts in aerospace applications?
No, eddy current proximity sensors require ferromagnetic target materials (steel, iron, Inconel). For non-ferrous metals, specify our accelerometer-based vibration sensors (model 330500 series) or laser displacement sensors for ultra-precision measurements.
How do I extend the cable length beyond the standard 5 meters?
Use Bently Nevada 330130 series extension cables rated for the same impedance (7.87Ω). Maximum total cable length is 60 meters when maintaining signal integrity. Avoid running cables parallel to high-voltage power lines; maintain 300mm minimum separation to prevent electromagnetic interference.
Is field calibration required after installing this proximity vibration sensor?
No, each probe ships with factory calibration performed on NIST-traceable equipment. The calibration remains valid provided the sensor is not mechanically damaged or exposed to temperatures exceeding +125°C. Recalibration recommended every 24 months or per plant maintenance procedures.
What is the minimum shaft diameter for reliable vibration measurement?
Target shaft diameter should be at least 8mm (0.315") to ensure adequate eddy current field development. For smaller shafts below 6mm, consult application engineering for feasibility assessment and potential sensitivity adjustments.
Does this sensor work with legacy Bently Nevada 7200 series monitors?
Yes, the 19000-00-95-12-02 is backward compatible with 7200 proximitor sensors when output impedance matches system requirements. Verify your 7200 module accepts 7.87Ω probes; some older variants require 8Ω ±10% tolerance.
