The Bently Nevada 330500-02-00 Velomitor Piezo-Velocity Sensor is a high-performance, solid-state transducer designed for measuring absolute vibration on bearing housings, machine casings, and structural components. Unlike traditional moving-coil velocity transducers, this unit utilizes specialized piezoelectric accelerometer technology with embedded integrated electronics, ensuring long-term reliability and immunity to mechanical wear.

Features

• Solid-state design with no moving parts for extended service life.
• Capable of mounting at any angle of orientation (vertical, horizontal, or angular).
• Incorporates embedded electronics for direct signal processing.
• High resonant frequency (>12 kHz) for accurate vibration monitoring.
• Robust construction suitable for demanding industrial environments.

Applications

• Rotating Machinery: Steam and gas turbines, compressors, pumps, and electric motors.
• Industrial Equipment: Fans, blowers, and centrifuges.
• Condition Monitoring: Detecting cavitation, misalignment, and structural looseness in high-speed machinery.

Technical Specifications

Installation Guidelines

• Mounting: Ensure the sensor is securely mounted to the machine casing or bearing housing using the specified M8 x 1 thread.
• Cabling: Use a 2-conductor twisted, shielded cable (e.g., 18 AWG) to maintain signal integrity and minimize EMI interference.
• Polarity: The sensor is configured such that movement toward the connector results in Pin A becoming positive relative to Pin B.
• Power: Ensure the power supply provides the required -12 VDC bias voltage.
• Environment: While the sensor is robust, avoid mounting in areas subject to extreme thermal shock or direct impact.

FAQs

What is the 330500-02-00 Sensor?

The 330500-02-00 is a Bently Nevada Velomitor Piezo-Velocity Sensor designed to measure absolute vibration relative to free space. It is a solid-state, specialized piezoelectric accelerometer with no moving parts, suitable for monitoring industrial machinery.

What is the function of the 330500-02-00?

It measures absolute bearing housing, casing, or structural vibration by converting mechanical vibration into an electrical signal for monitoring and analysis.

Can this sensor be mounted in any orientation?

Yes, because the sensor uses solid-state electronics and has no moving parts, it does not suffer from mechanical degradation and can be mounted vertically, horizontally, or at any other angle of orientation.
