Product Introduction
The Bently Nevada 330101-00-40-10-02-00 is a premium non-contact proximity probe designed for precise measurement of shaft vibration and position in rotating machinery. Manufactured by Bently Nevada, a part of Baker Hughes, this model is a key component in the 3300 XL 8mm series—engineered specifically for applications requiring API 670 compliance and high-reliability performance in industrial environments.
This particular model features a 40-inch unarmored probe with a 1.0 meter integral coaxial cable, designed to connect directly to a 3300 XL Proximitor® Sensor. It provides superior linearity, sensitivity, and environmental resistance, making it ideal for monitoring critical machinery such as turbines, compressors, and large motors.
The 330101-00-40-10-02-00 is part of a fully modular system, which includes the probe, extension cable, and Proximitor sensor—each of which can be replaced independently.
