Bently Nevada 330780-50-00 3300 XL 11 mm Proximitor Sensor

Here is the detailed product introduction and technical specifications for the Bently Nevada 330780-50-00 3300 XL 11 mm Proximitor® Sensor.

Bently Nevada 330780-50-00 3300 XL 11 mm Proximitor® Sensor - Product Introduction

The Bently Nevada 330780-50-00 is a high-performance 3300 XL 11 mm Proximitor® Sensor designed for non-contact measurement of vibration, displacement, and position in critical rotating machinery . As the signal conditioning core of the 3300 XL 11 mm proximity transducer system, this sensor processes signals from 11 mm eddy current probes and converts them into linear voltage outputs proportional to the target distance .

This specific configuration features a 5.0-meter (16.4 feet) system length with panel mount installation and carries no specific agency approvals (denoted by the "-00" suffix), making it suitable for standard industrial applications where hazardous area certifications are not required .

The 3300 XL 11 mm system is designed to replace older 7200-series 11 mm and 14 mm transducer systems, offering improved performance and enhanced features .

Key Features and Benefits

Extended Linear Range

The 11 mm probe design provides a 2.54 mm (100 mils) linear range, significantly larger than standard 8 mm systems . This extended range makes it ideal for applications requiring larger measurement spans, such as axial thrust position monitoring, differential expansion, and reciprocating compressor rod position measurements .

High Precision Measurement

Delivers 3.94 V/mm (100 mV/mil) or 7.87 V/mm (200 mV/mil) sensitivity (depending on configuration) with exceptional accuracy for detecting minute changes in shaft position and vibration . The frequency response range of 0 to 10 kHz supports both dynamic vibration and static displacement measurements simultaneously .

API 670 Compliance

Fully compliant with the American Petroleum Institute's API 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability, ensuring reliability in critical turbomachinery applications .

Enhanced EMI/RFI Immunity

Advanced electromagnetic interference immunity satisfies CE mark approvals without requiring special shielded conduit or metallic housings. The sensor can be installed in fiberglass enclosures without adverse effects from nearby radio frequency signals, reducing installation complexity and cost .

Complete Component Interchangeability

Supports 100% interchangeability with 3300 XL 11 mm probes and extension cables. Any component can be replaced without bench calibration or system matching, reducing downtime and spare parts inventory .

Robust Environmental Protection

Features IP67-rated dust-tight and waterproof construction, corrosion-resistant materials, and operates across a wide temperature range suitable for harsh industrial environments .

Versatile Mounting Options

The mounting base provides electrical isolation, eliminating the need for separate isolator plates. SpringLoc terminal strips enable faster, more robust field wiring connections without special tools .
