Quick Detail

Description

The 330500-02-04 Velomitor Piezo-velocity Sensor is a specialized, industrial-grade vibration transducer engineered by Bently Nevada for high-precision machinery protection. As a core component of the 330500-02-04 Velomitor Piezo-velocity Sensor series, this device is designed to measure absolute casing vibration on rotating machinery. Unlike traditional moving-coil transducers, the 330500-02-04 Velomitor Piezo-velocity Sensor utilizes advanced piezoelectric technology, which incorporates an internal solid-state electronic circuit to eliminate moving parts. This robust design ensures that the 330500-02-04 Velomitor Piezo-velocity Sensor provides superior reliability and an extended service life, even when exposed to continuous high-vibration industrial environments.

The internal architecture of the 330500-02-04 Velomitor Piezo-velocity Sensor integrates a sensing element with a charge amplifier, enabling the sensor to perform signal integration internally. This process converts the raw acceleration data into a high-fidelity velocity signal. The 330500-02-04 Velomitor Piezo-velocity Sensor provides a standardized sensitivity of 3.94 mV/mm/s (100 mV/in/s), ensuring seamless compatibility with various monitoring systems. Because the 330500-02-04 Velomitor Piezo-velocity Sensor generates a low-impedance voltage output, the signal remains clear and accurate over long distances, resisting the electromagnetic interference (EMI) often found in power generation and petrochemical facilities.

This specific 330500-02-04 Velomitor Piezo-velocity Sensor configuration includes the "02" mounting thread option (M8 x 1) and the "04" agency approval option, which signifies Multi-Approvals (including ATEX, IECEx, and CSA) for hazardous locations. The 330500-02-04 Velomitor Piezo-velocity Sensor is housed in 316L stainless steel, providing exceptional corrosion resistance.

Applications

1.Monitoring General Rotating Machinery

The 330500-02-04 Velomitor is primarily used to measure the absolute vibration of machine casings. It is the gold standard for identifying common mechanical faults such as unbalance, shaft misalignment, and mechanical looseness. By providing a velocity-based output, it allows operators to assess machine health according to ISO 10816 standards.

2.Hazardous Area Deployments

With its 04 Multi-Approval rating (ATEX/IECEx/CSA), the 330500-02-04 is specifically designed for use in explosive atmospheres. It is widely applied in oil and gas refineries, chemical processing plants, and offshore platforms where safety certifications are mandatory for electronic instrumentation.

3.Remote Monitoring Systems

Thanks to its low-impedance output (less than 2300 Ω), this sensor is perfect for facilities where the monitoring room is located far from the actual machinery. It can drive signals over long cable runs (up to the included 5.0 meters and beyond) without significant signal loss or susceptibility to industrial noise.

Specifications

Competitive Advantage

1.Solid-State Piezoelectric Technology

The 330500-02-04 outperforms older electro-mechanical sensors by utilizing a completely solid-state design. With no moving coils or springs to wear out or "stick," this sensor provides virtually infinite mechanical life and maintains its calibration accuracy far longer than moving-coil alternatives.

2.Integrated Internal Electronics

A key advantage is the internal integration of the signal conditioner. By converting acceleration to velocity inside the 316L stainless steel housing, the sensor outputs a robust, low-impedance signal. This prevents the "noise" issues commonly associated with high-impedance cables, ensuring that the 100 mV/in/s sensitivity remains precise from the sensor head to the control system.

3.Global Certification Compliance

The "04" option provides a "Triple Crown" of hazardous area approvals (North American CSA, European ATEX, and International IECEx). This allows global engineering firms to standardize on one specific model (330500-02-04) for projects worldwide, significantly reducing spare parts inventory and simplifying international safety documentation.

4.Exceptional Environmental Durability

Constructed with a 316L stainless steel case and capable of operating in temperatures ranging from -50 °C to +120 °C, the Velomitor is built for the harshest environments. Its hermetic sealing and rugged connector options ensure that moisture, oil, and dust do not compromise vibration data.
