Functional Description

330500-01-05 is a Velomitor Piezo-velocity Sensor manufactured by Bently Nevada. It is a part of 330500 system. It is engineered to provide precise and reliable measurements of absolute vibration for bearing housings, machine casings, and structural components.

Features

• Mounting Thread Adaptor Option: 1/2 - 20 UNF.
• Piezoelectric Technology: Uses an advanced piezoelectric accelerometer with embedded solid-state electronics, ensuring long-term reliability.
• Flexible Orientation: Can be installed in vertical, horizontal, or angular positions without impacting performance.
• No Mechanical Wear: Designed without moving parts, eliminating degradation due to wear and extending its operational lifespan.

Applications

The 330500 sensor is ideal for monitoring machinery where absolute vibration measurements are critical for protection and diagnostics, such as:

• Turbines
• Compressors
• Pumps
• Motors

Design and Functionality

The solid-state design ensures that the sensor is immune to mechanical degradation, making it durable and suitable for harsh environments.
It measures absolute vibration relative to free space, capturing data about changes in rotor vibration caused by common issues such as unbalance, misalignment, or looseness.

Installation Guidelines

• Location: Install the transducer on the bearing housing or machine casing to ensure accurate vibration transmission.
• Orientation: The sensor supports various orientations but must be securely mounted to avoid improper data collection.
• Avoid False Signals: Improper installation can decrease the sensor’s amplitude and frequency response or generate false readings, compromising the data's reliability.

Benefits

• Reliable Measurements: Measures rotor-originated vibrations transmitted to the casing, ensuring effective machinery monitoring.
• Durable Construction: The piezoelectric design with solid-state electronics ensures no wear and long-lasting performance.
• Accurate Diagnostics: Aids in detecting and diagnosing machine malfunctions such as unbalance, misalignment, and looseness.
