Product Overview
Description
The 330500-02-05 Velomitor Piezo-velocity Sensor is a high-precision, rugged vibration transducer designed specifically for monitoring the casing vibration of rotating machinery. As a premier solution in the 330500-02-05 Velomitor Piezo-velocity Sensor category, this device utilizes advanced piezoelectric technology to measure absolute vibration velocity directly. Unlike traditional moving-coil velocity transducers, the 330500-02-05 Velomitor Piezo-velocity Sensor contains no moving parts, which eliminates the risk of mechanical wear and ensures an exceptionally long service life even in high-vibration environments. The 330500-02-05 Velomitor Piezo-velocity Sensor is engineered to provide a standard output of 3.94 mV/mm/s (100 mV/in/s), making it compatible with a wide range of industrial monitoring systems.
One of the primary advantages of the 330500-02-05 Velomitor Piezo-velocity Sensor is its internal integration of a solid-state electronic circuit. This circuitry enables the 330500-02-05 Velomitor Piezo-velocity Sensor to convert the initial acceleration signal from the piezoelectric element into a velocity signal within the sensor housing itself. Consequently, the 330500-02-05 Velomitor Piezo-velocity Sensor provides a low-impedance voltage output that is highly resistant to electromagnetic interference (EMI) and signal degradation over long cable runs. This specific 330500-02-05 Velomitor Piezo-velocity Sensor configuration features an M8 x 1 mounting thread (02 option) and carries Multiple Approvals (05 option), including ATEX, IECEx, and CSA certifications, allowing for safe deployment in hazardous industrial areas.
Key Functions
Applications
1.General Machinery Casing Vibration Monitoring
The primary application for the 330500-02-05 is the measurement of absolute casing vibration on rotating equipment. Because velocity is often the best indicator of overall machine health, this sensor is used to detect common mechanical faults such as unbalance, misalignment, and looseness. Its 100 mV/in/s sensitivity provides a clear, high-resolution signal that allows plant operators to track vibration trends and set alarm limits based on ISO 10816 standards.
2.Balance-of-Plant (BoP) Equipment Protection
This sensor is a standard choice for "Balance of Plant" assets, including centrifugal pumps, cooling tower fans, blowers, and small air compressors. Unlike displacement probes that require a proximity to the shaft, the Velomitor is easily mounted to the exterior bearing housing using the M8 x 1 mounting thread. This makes it an ideal solution for machines where internal shaft access is impossible or impractical.
3.Remote Monitoring with Long Cable Runs
Because the 330500-02-05 provides a low-impedance voltage output (less than 2300 Ω), it is capable of driving signals over long distances without high-frequency loss. This makes it suitable for large facilities where the machinery is located far from the monitoring rack or PLC. The integrated electronics handle the signal conditioning at the source, ensuring that the 3.90 mV/mm/s signal remains accurate even in the presence of industrial electromagnetic noise.

Compatibility & Ordering Notes
Competitive Advantage
1.Solid-State Reliability with No Moving Parts
Unlike legacy electro-mechanical velocity sensors that rely on a moving coil and spring assembly, the 330500-02-05 is entirely solid-state. This piezoelectric design eliminates mechanical wear, sticking, and friction. This provides a significant competitive edge in terms of longevity and reliability, especially on machines with high-frequency background vibration that would quickly degrade the internal components of a moving-coil sensor.
2.Superior Signal Integrity via Internal Integration
A major advantage of the Velomitor is its ability to perform signal integration (acceleration to velocity) inside the sensor housing. By converting the signal at the source, the 330500-02-05 outputs a low-impedance voltage (less than 2300 Ω). This makes the signal much less susceptible to cable-induced noise and electromagnetic interference (EMI) compared to high-impedance acceleration signals. This ensures that the 100 mV/in/s sensitivity remains accurate even across the included 5.0-meter cable run.
3.Global Hazardous Area Versatility
With the -05 Agency Approval Option, this sensor carries a "triple crown" of certifications: CSA, ATEX, and IECEx. This allows global enterprises to standardize on a single part number for their facilities worldwide. Whether the asset is located in a North American refinery or a European chemical plant, the 330500-02-05 meets the stringent safety requirements for explosive atmospheres, simplifying procurement and spare parts management.
