Product Overview

The 3300-5-1 is a high-precision, non-contact displacement sensor manufactured by Bently Nevada, a global leader in industrial condition monitoring. It is a critical component of the 3300 XL sensing system, specifically designed to measure the relative motion between a conductive target (typically a rotating shaft) and the probe tip. This 5mm diameter probe utilizes eddy current technology to provide accurate, real-time data on shaft vibration, shaft position, and proximity.

At its core, the 3300-5-1 is an eddy current sensor that generates an electromagnetic field. When the conductive target (such as a metal shaft) enters this field, eddy currents are induced, altering the impedance of the coil within the probe. This change in impedance is converted into a DC voltage output that is directly proportional to the distance between the probe tip and the target surface. The device is renowned for its stability, reliability, and ability to operate in harsh industrial environments.

The 3300-5-1 is designed to be used in conjunction with a 3300 series monitor or transmitter, such as the 990-05-xx-01-00_mod_147202-01 or 1800_20-xx-90-02-00_mod_158611-01. which provide the necessary excitation and signal conditioning to convert the raw sensor data into meaningful engineering units. This probe is a vital tool for predictive maintenance, allowing operators to detect early signs of mechanical issues before they lead to catastrophic failure.

Main Features and Advantages

High-Frequency Response

The 3300-5-1 features a wide frequency response range, capable of detecting high-frequency vibration components up to 10.000 Hz. This capability is essential for capturing detailed information about the dynamic behavior of rotating machinery, including bearing defects, gear mesh frequencies, and rubs. The high-frequency response ensures that the probe can provide a comprehensive picture of the machine’s health, making it an invaluable tool for vibration analysts and reliability engineers.

Versatile Mounting Options

Bently Nevada offers the 3300-5-1 in various mounting configurations to suit different application requirements. The standard probe features a 90-degree mounting orientation, while the 3300-5-1 is also available in an extended length version (e.g., 3300-5-1-01) for applications where the target is recessed or difficult to access. The probe’s ceramic tip provides excellent thermal stability and resistance to wear, ensuring consistent performance over time.
