Bently Nevada 330101-085-00-00 3300 XL 8 mm Proximity Probe

Overview

The Bently Nevada 330101-085-00-00 is part of the 3300 XL 8 mm Proximity Transducer System. It is designed for vibration and position measurements on fluid-film bearing machines, as well as Keyphasor and speed measurements. This proximity probe features a 3/8-24 UNF thread and operates without armor. It provides superior performance and is fully compliant with the API 670 standard for mechanical configuration, linear range, accuracy, and temperature stability.

Technical Specifications

Electrical Specifications

• Proximitor Sensor Input: Accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm Proximity Probe and Extension Cable.
• Power Supply: Requires -17.5 Vdc to -26 Vdc with a 12 mA maximum consumption. With barriers, it operates at -23 Vdc to -26 Vdc. Operating at a more positive voltage than -23.5 Vdc may reduce the linear range.
• Supply Sensitivity: Exhibits less than 2 mV change in output voltage per volt change in input voltage.
• Output Resistance: 50 Ω.

Performance Characteristics

• Accuracy: The performance characteristics apply only to systems using 3300 XL 8 mm components and an AISI 4140 steel target. The system's accuracy and interchangeability are not guaranteed when using other target materials.
• Target Material: The system is calibrated for an AISI 4140 steel target.
• Gap: The probe should be gapped at 1.27 mm (50 mils) for optimal performance.

Operating Conditions

• Temperature Range: The system operates effectively between +18°C and +27°C (+64°F to +80°F).
• Altitude: Suitable for use at altitudes up to 2000 meters.
