The Bently Nevada 330500-01-01 is a high-performance Velomitor Piezo-velocity sensor designed for the measurement of absolute vibration on bearing housings, machine casings, and structural components. By utilizing advanced piezoelectric accelerometer technology with integrated solid-state electronics, this sensor provides a reliable velocity output without the mechanical wear associated with traditional moving-coil transducers.

Features

  • Solid-state design with no moving parts for extended service life.
  • Integrated electronics allow for mounting in any orientation (vertical, horizontal, or angled).
  • Immune to mechanical degradation common in older velocity transducer technologies.
  • Standard 1/2-20 UNF mounting thread for secure installation.
  • CSA/US/C certified for hazardous area compliance.

Applications

  • Turbines: Monitoring absolute bearing housing vibration in steam and gas turbine sets.
  • Compressors and Fans: Ideal for centrifugal and axial compressors, as well as cooling tower blowers.
  • Pumps and Motors: Suitable for horizontal and vertical pump trains and electric motor drive systems.
  • Industrial Processing: Widely used in power generation, oil and gas, petrochemical, and steel manufacturing facilities.

Installation Guidelines

  • Connector Engagement: Secure the 2-pin Mil-C-5015 connector firmly. If a protective boot is utilized, ensure it is seated correctly over the lip above the hex flats.
  • Polarity: Pin A provides a positive signal relative to Pin B when the sensor case moves toward the connector.
  • Cable Management: Maintain a minimum cable bend radius of 38.1 mm (1.5 inches) to prevent internal conductor damage.
  • Signal Integrity: The sensor supports cable runs up to 305 meters (1,000 feet) without significant signal degradation.
  • Handling: As a precision instrument, handle with care to avoid impact damage to the piezoelectric element. Ensure the mounting surface is clean and flat for accurate vibration transmission.

FAQ

What is the primary function of the 330500-01-01?

The sensor is designed to measure absolute vibration relative to free space, converting acceleration signals into a velocity output for monitoring bearing housing and structural health.

Can this sensor be mounted in any position?

Yes, because the unit utilizes solid-state electronics and contains no moving parts, it is not position-sensitive and can be installed at any angle.

What is the significance of the -01-01 suffix?

The first -01 indicates the 1/2-20 UNF mounting thread configuration, and the second -01 denotes the specific agency approval package (CSA/US/C).
