Quick Detail

Description

The 330500-03-00 Velomitor Piezo-velocity Sensor is a high-precision, rugged vibration monitoring transducer engineered and manufactured by Bently Nevada in the USA, tailored exclusively for real-time casing vibration measurement of industrial rotating machinery. As a core component of Bently Nevada’s machinery condition monitoring portfolio, this sensor leverages advanced piezoelectric technology to deliver direct, accurate absolute vibration velocity data, eliminating the mechanical wear and failure risks associated with traditional moving-coil velocity transducers by adopting a 100% solid-state design with no moving parts. Boasting a calibrated sensitivity of 3.70 mV/mm/s (100 mV/in/s) ±5%, the 330500-03-00 Velomitor Piezo-velocity Sensor ensures consistent, high-resolution signal output that aligns with ISO 10816 standards, making it fully compatible with a wide range of industrial monitoring systems, PLCs, and data acquisition platforms.

A key technical advantage of the 330500-03-00 Velomitor Piezo-velocity Sensor lies in its integrated solid-state electronic circuit, which performs in-situ signal conversion—transforming the raw acceleration signal from the piezoelectric element into a low-impedance velocity signal directly within the sensor housing. This integrated design not only simplifies system integration but also significantly enhances signal integrity, as the low-impedance output (less than 2300 Ω) is highly resistant to electromagnetic interference (EMI) and signal degradation even over extended cable runs, including the sensor’s standard 5.0-meter (16.4 feet) industrial cable. Configured with a 1/4 - 28 UNF mounting thread adaptor, an overall case length of 40 mm, and a miniature coaxial ClickLoc connector with a protective housing, the 330500-03-00 Velomitor Piezo-velocity Sensor offers exceptional installation flexibility, fitting seamlessly into confined machinery spaces and enabling quick, secure mounting on bearing housings of turbines, pumps, fans, and compressors.

Applications

The 330500-03-00 Velomitor Piezo-velocity Sensor is primarily used for absolute casing vibration monitoring of rotating machinery such as centrifugal pumps, cooling tower fans, blowers, and small air compressors, providing accurate velocity data that serves as a key indicator of machine health to detect common faults including unbalance, misalignment, and structural looseness in real time.

Equipped with a 1/4 - 28 UNF mounting thread adaptor and a compact 40 mm case length, this sensor is ideal for balance-of-plant (BoP) equipment protection scenarios where internal shaft access is impossible or impractical, allowing maintenance teams to mount the device directly on exterior bearing housings without complex modifications to machinery structures.

With its low-impedance signal output (less than 2300 Ω) and 5.0-meter standard cable, the 330500-03-00 Velomitor Piezo-velocity Sensor supports remote monitoring applications in large industrial facilities, where machinery is located far from central monitoring racks or PLC systems, ensuring signal accuracy and resistance to EMI even over long transmission distances.

Specifications

Competitive Advantage

1.Solid-State Design for Unmatched Durability and Longevity

Unlike traditional moving-coil velocity sensors with vulnerable mechanical components, the 330500-03-00 Velomitor Piezo-velocity Sensor features a 100% solid-state piezoelectric structure with no moving parts. This eliminates risks of mechanical wear, sticking, and friction, enabling reliable operation in high-vibration industrial environments and extending the sensor’s service life significantly compared to conventional alternatives.

2.Integrated Signal Conditioning for Superior Signal Integrity

The sensor integrates a solid-state electronic circuit inside its housing, converting raw acceleration signals to low-impedance velocity signals at the source. This design minimizes signal degradation and EMI susceptibility during transmission, even over the 5.0-meter cable run, ensuring the 3.70 mV/mm/s sensitivity remains stable and accurate for precise machinery condition monitoring.

3.Optimized Installation Flexibility for Diverse Industrial Scenarios

Configured with a 1/4 - 28 UNF mounting thread adaptor, a compact 40 mm case length, and a miniature coaxial ClickLoc connector with a protector, the 330500-03-00 Velomitor Piezo-velocity Sensor fits easily into confined spaces and supports quick, secure mounting on various rotating machinery bearing housings. Its lightweight (0.14kg) and compact dimensions further reduce installation labor time and costs, enhancing overall operational efficiency.
