The 330180-90-00 is a high-performance eddy current displacement sensor preamplifier. It belongs to the Bently 3300 XL series and is commonly used in industrial environments for vibration and displacement monitoring of rotating machinery.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements. The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components.

When using the 330180-90-00 Proximitor, ensure the total system length strictly matches 9.0 meters, securely mount it on a DIN rail, and ensure the casing is properly grounded to eliminate EMI. Additionally, regularly verify that the supply voltage (typically -24 VDC) and output gap voltage remain within the linear range, and strictly avoid plugging or unplugging coaxial connectors while energized to prevent damage to precision electronic components.
