Hardware Specifications

Rotor Dynamics and Gap Voltage Validation

Designed for extreme thermal environments, this proximity probe preserves precise eddy-current probe scaling to ensure linear voltage output corresponding to shaft displacement. During commissioning, gap voltage validation targets a nominal -10 VDC baseline when interfaced with a matched 3300 XL Proximitor sensor. Furthermore, robust coaxial shielding combined with stainless steel armor execution ensures cross-talk suppression and isolates the high-frequency carrier signal from electromagnetic interference inside heavy industrial enclosures.

Standard Scope of Supply

• 1 x Bently Nevada 330194-15-25-50-05 Extended Temperature Range Proximity Probe
• 1 x M10 x 1 Mounting Locknut Set
• 1 x Hazardous Area Certification Documentation Insert

Mechanical Installation and Mounting Guidelines

• Thread Engagement Limits: Ensure the mounting bracket hole is free of debris and that maximum thread engagement of the M10 x 1 probe case does not exceed 15 mm.
• Torque Specifications: Tighten the probe case to a recommended torque of 5.1 N m (45 in lb), ensuring the limit does not exceed 7.3 N m (65 in lb) to avoid thread stripping.
• Transductor Separation: Maintain a minimum side clearance of 25 mm (1.0 in) between adjacent transducer tips to prevent electromagnetic cross-talk interference during multi-probe setups.

Frequently Asked Questions

• What is the designated cable length for this probe assembly?

  The total integrated cable length is 5.0 meters (16.4 feet) as specified by the 50 suffix code.

• What thread size is utilized on the probe case housing?
