The 330500-02-00 is a piezoelectric velocity sensor manufactured by Bently Nevada. Featuring a solid-state design, it is specifically engineered to measure the absolute vibration (relative to free space) of bearing housings, machine casings, or structural components.
Functions & Advantages
The Bently Nevada 330500 piezoelectric velocity sensor is primarily utilized for vibration velocity measurements; it converts mechanical vibrations into electrical signals, thereby providing accurate data for monitoring and analysis purposes. The sensor incorporates solid-state electronic technology and contains no moving parts, eliminating concerns regarding mechanical degradation or wear. It can be mounted vertically, horizontally, or at any arbitrary angle.

FAQ
1. What is the function of the 330500 Sensor?
—Primarily used for continuous, high-precision vibration velocity measurement.
2. What is the difference between the 330400 sensor and the 330500?
—The 330400 is an accelerometer, designed specifically for critical machinery applications where casing acceleration measurement is required. The 330500, conversely, is suitable for monitoring the mechanical condition of rolling-element bearings, as well as for applications where vibration measurements need to be expressed in velocity units.
3. Why is my newly purchased 330500 unit providing inaccurate measurements?
—This may be due to an incorrect installation configuration. Extreme care must be exercised when installing the 330500 accelerometer; it should be properly mounted on the bearing housing or the machine casing. Improper installation can degrade the sensor's amplitude and frequency response performance, or even generate spurious signals that fail to accurately reflect actual vibrations.
4. How should I troubleshoot the device if a fault occurs?
—Troubleshooting should focus primarily on the cable, connectors, and installation status. Since the 330500 sensor is a hermetically sealed, integral unit containing no internal adjustable components, if the sensor body itself is damaged, the entire unit must be replaced.
