Quick Detail

Description

The Bently Nevada 330500-00-00 Velomitor Piezo-Velocity Sensor is a cutting-edge device designed to accurately measure the absolute vibration of bearing housings, casings, or structural elements in relation to free space. The 330500 Velomitor sensor is a piezoelectric unit equipped with integrated solid-state electronics, offering a rugged and reliable solution for vibration monitoring across various industries.

One of the most notable features of the 330500 is its solid-state construction, which eliminates mechanical components that are commonly found in traditional sensors. This design greatly enhances its durability, as the sensor is immune to wear and mechanical degradation over time. The absence of moving parts ensures that the Velomitor can operate effectively without the typical wear issues that can compromise the performance of mechanical systems. As a result, it offers long-term reliability with minimal maintenance needs, making it perfect for high-vibration environments such as power plants, refineries, and manufacturing facilities.

Designed to be versatile, the 330500 Velomitor can be installed in a variety of orientations, including vertically, horizontally, or at any other angle, providing flexibility for different application requirements. This adaptability makes it a highly flexible solution for mounting on various types of machinery or structural components where vibration monitoring is critical.

Thanks to its solid-state electronics, the Velomitor sensor operates continuously without being affected by mechanical wear or friction, which often results in inaccurate readings in traditional sensors with moving parts. This makes it particularly valuable in demanding environments where consistent and precise measurements are needed to detect issues like misalignment, imbalance, or wear before they result in costly failures.

Applications

The 330500-00-00 Velomitor Piezo-velocity Sensor is a high-performance vibration monitoring solution for critical industrial machinery, delivering reliable velocity measurement across diverse environments. As a dedicated piezo-velocity sensor, it excels in detecting vibration amplitude and frequency of rotating, reciprocating, and stationary equipment—serving as a core component in predictive maintenance systems for power generation, oil and gas, chemical processing, and manufacturing.Crafted from 316L stainless steel, it offers exceptional corrosion resistance and durability, ideal for harsh settings like offshore platforms, chemical plants, and wastewater facilities. With compact dimensions (6.7x2.4x2.4cm) and lightweight design (0.14kg), it fits seamlessly into space-constrained installations—including tight equipment cavities, dense pipelines, and small machinery (e.g., fractional horsepower motors, precision pumps). No mounting thread adapter simplifies installation, enabling direct integration with standard brackets or adhesive fixtures.​Boasting an operating temperature range of -55°C to 121°C (-67°F to 250°F), the sensor maintains stable performance in extreme thermal conditions—from arctic outdoor equipment to high-temperature industrial ovens. Its temperature sensitivity (-14% to +7.5% over the operating range) ensures accuracy amid thermal fluctuations, eliminating the need for external compensation.

Specifications

Competitive Advantage

1. Exceptional Measurement Accuracy & Consistent Data Integrity​

Boasting a sensitivity of 3.94 mV/mm/s (100mV/in/s) ±5% and a wide velocity range of 1270 mm/s (50 in/s) peak, this sensor accurately captures low to high-amplitude vibrations. Its exceptional amplitude linearity (±2% up to 152 mm/s / 6 in/s peak) ensures consistent and reliable data output, enabling early detection of equipment anomalies such as bearing wear and shaft misalignment. With a dynamic output impedance of less than 2400 Ω, it maintains signal integrity when paired with most industrial data acquisition systems, outperforming competitors with higher impedance that may cause signal loss.

2. Durable 316L Stainless Steel Construction for Longevity​

Constructed from high-quality 316L stainless steel, the sensor offers superior corrosion resistance and mechanical strength, making it suitable for harsh industrial environments (e.g., chemical plants, offshore platforms). Its compact dimensions (6.7x2.4x2.4cm) and lightweight design (0.14kg) balance portability and sturdiness, while the 63.5 mm (2.5 in) overall case length and 9.53 mm (0.375 in) unthreaded length optimize structural stability during operation. Compared to sensors with plastic or ordinary steel casings, it resists wear, moisture, and chemical erosion, extending service life by 50% in demanding conditions.

​

3. Broad Thermal Tolerance for Multi-Scenario Adaptability​

With an operating temperature range of -55°C to 121°C (-67°F to 250°F), the sensor performs reliably in extreme thermal conditions—from arctic outdoor equipment to high-temperature industrial ovens. Its temperature sensitivity (ranging from -14% to +7.5% over the operating range) ensures measurement accuracy without the need for external temperature compensation devices, reducing additional costs. This wide adaptability surpasses standard sensors (typically -40°C to 85°C), expanding its application scope across indoor, outdoor, and extreme-temperature industrial scenarios.
