Quick Detail

Description

The 330500-00-02 Velomitor Piezo-velocity Sensor represents the pinnacle of Bently Nevada’s transducer technology, specifically engineered for high-precision monitoring of absolute vibration. Unlike traditional moving-coil velocity transducers, the 330500-00-02 is a sophisticated Velomitor Piezo-velocity Sensor that utilizes a solid-state piezoelectric design to capture bearing housing, casing, or structural vibration relative to free space. This specific model, 330500-00-02, integrates advanced embedded electronics that convert the charge signal from the piezoelectric element directly into a velocity output, providing a clean and reliable signal for machinery protection systems.

One of the most significant advantages of the 330500-00-02 Velomitor Piezo-velocity Sensor is its durability. Because the 330500-00-02 incorporates solid-state integrated electronics and contains absolutely no moving parts, it is inherently immune to the mechanical degradation and physical wear that often plague older mechanical velocity sensors. This "no-wear" design ensures that the Velomitor Piezo-velocity Sensor maintains its calibration integrity over long periods, even in high-vibration environments. Furthermore, the 330500-00-02 offers unparalleled installation flexibility; it can be mounted vertically, horizontally, or at any oblique angle without affecting its measurement accuracy or internal lifespan.

In industrial applications, the 330500-00-02 Velomitor Piezo-velocity Sensor is the preferred choice for monitoring rotating machinery where frequency response and signal-to-noise ratio are critical. The 330500-00-02 is particularly effective at detecting casing-related issues that might be missed by proximity probes alone. By utilizing this Velomitor Piezo-velocity Sensor, maintenance teams can transition from reactive repairs to proactive condition-based monitoring. The robust construction of the 330500-00-02 ensures it thrives in harsh industrial sectors, including power generation, oil and gas, and wastewater treatment.

Applications

1.General Machinery Casing Vibration Monitoring

The primary application of the 330500-00-02 is measuring the absolute vibration of bearing housings and machine casings. With a sensitivity of 3.93 mV/mm/s and a robust 316L stainless steel case, it is ideal for monitoring general-purpose equipment like pumps, fans, and small motors. Its solid-state design allows for vibration detection across a broad velocity range of up to 1270 mm/s peak, ensuring that even high-energy mechanical events are captured without sensor saturation.

2.Hazardous Area Monitoring in European Markets

Equipped with the ATEX (European) Agency Approval, the 330500-00-02 Velomitor Piezo-velocity Sensor is specifically intended for use in potentially explosive atmospheres common in European industrial sites. This makes it a critical component for refineries, chemical plants, and gas processing facilities that must adhere to strict safety directives. The sensor's ability to operate safely in these zones while providing high-fidelity velocity data ensures both plant safety and asset reliability.

3.Extreme Temperature Industrial Environments

The 330500-00-02 is engineered to perform in thermal extremes, with an operating temperature range of -54°C to 120°C. This makes it suitable for applications in both cryogenic environments and high-heat areas near steam-driven machinery. While temperature sensitivity varies slightly over this range (-13% to +7.4%), the sensor remains a reliable choice for outdoor installations in extreme climates or for monitoring hot process pumps where standard sensors might fail.

4.Integration into High-Impedance Monitoring Systems

With a dynamic output impedance of less than 2400 Ω, the 330500-00-02 Velomitor Piezo-velocity Sensor is designed for seamless integration with Bently Nevada monitoring racks and other high-impedance data acquisition systems. Its excellent amplitude linearity (±2%) up to 152 mm/s peak ensures that the data used for trending and diagnostic analysis is highly accurate, making it a preferred tool for maintenance teams performing root-cause analysis on recurring machinery issues.

Specifications

Competitive Advantage

1.Superior Material Integrity with 316L Stainless Steel

One of the most significant advantages of the 330500-00-02 is its 316L stainless steel housing. Unlike standard sensors made from basic alloys, 316L provides exceptional resistance to pitting and crevice corrosion, especially in environments containing chlorides or acidic process gases. This makes the Velomitor Piezo-velocity Sensor exceptionally durable for offshore platforms, marine applications, and chemical processing plants where longevity is a critical cost-saving factor.

2.Optimized Signal Precision and Amplitude Linearity

The 330500-00-02 offers an elite level of signal accuracy with an amplitude linearity of ±2% up to 152 mm/s (6 in/s) peak. This precision ensures that the velocity data provided to the monitoring system is a true reflection of the machine's condition, minimizing the risk of false alarms or missed fault detections. With a sensitivity of 3.93 mV/mm/s, this Velomitor Piezo-velocity Sensor captures subtle changes in mechanical health that other sensors might overlook.

3.Specialized ATEX Certification for European Markets

The inclusion of the ATEX (European) Agency Approval gives the 330500-00-02 a decisive edge for projects requiring strict compliance with hazardous area directives. This certification allows for seamless integration into European industrial frameworks, ensuring that the Velomitor Piezo-velocity Sensor meets the highest safety standards for explosive atmospheres. It eliminates the administrative and safety hurdles of using non-certified equipment in regulated zones.

4.Wide-Spectrum Thermal Versatility

With an impressive operating temperature range from -54°C to 120°C, the 330500-00-02 Velomitor Piezo-velocity Sensor is designed to maintain performance in extreme climates. Whether installed in arctic conditions or high-temperature pump rooms, its ability to withstand thermal stress while keeping temperature sensitivity within a tight range (-13% to +7.4%) ensures data consistency across all four seasons and varyingprocess loads.
