Bently Nevada 330180-50-05 3300 XL 8mm probe Proximitor Sensor

Bently Nevada 330180-50-05 3300 XL Series 5/8 mm Proximitor Sensor is a critical device used for condition monitoring of rotating machinery.

It is not a standalone probe but rather the signal processing unit within an eddy current sensor system. It must be used in conjunction with an 8mm probe and an extension cable to accurately measure shaft vibration, displacement, and speed.

Core Product Information Details

here is a summary of its key information:

Product Name: 3300 XL Series 5/8 mm Proximitor Sensor

Brand & Series: Bently Nevada, 3300 XL Series

Part Number (PNR): 330180-50-05

Core Function: Provides excitation current to the probe, receives and processes the signal from the 8mm probe, and converts it into a voltage output proportional to the gap. This output is then supplied to monitoring systems (such as the 3500/3300 Rack).

Key Features:

Full Interchangeability: Supports complete interchangeability with 3300 XL Series probes and extension cables without requiring individual matching or calibration.

Flexible Mounting: Supports both traditional panel mounting and high-density DIN rail mounting. The mounting base provides electrical isolation, eliminating the need for a separate isolation plate.

Standards Compliance: Fully complies with American Petroleum Institute API 670 standard (4th edition), ensuring reliability in harsh industrial environments.

Detailed Technical Specifications

Power Requirement: Requires -17.5 Vdc to -26 Vdc DC power supply (when used without barriers), with a maximum current consumption of 12 mA.

System Length: The (-50 suffix) in this model designates a 5-meter total system length (including the probe and extension cable) and utilizes panel mounting.

Input Compatibility: Accepts one 3300 series 5mm, 8mm, or 3300 XL 8mm non-contact probe and extension cable.

Approvals: The -05 suffix indicates it carries multiple hazardous area approvals, including CSA, ATEX, and IECEx.

Output Signal: The typical output is -1 Vdc to -17 Vdc, proportional to the gap between the probe and the target surface.

Linear Range: The standard linear range is 2 mm (80 mils), with a recommended installation gap setting of 1.27 mm (50 mils).

Sensitivity: Typical sensitivity is 7.87 V/mm (200 mV/mil).
