Quick Detail

Description

The 330500-00-20 Velomitor Piezo-velocity Sensor is a high-precision vibration monitoring device designed to measure the absolute velocity of rotating machinery, structural components, and bearing housings with exceptional accuracy. Utilizing advanced piezoelectric technology combined with integrated solid-state electronics, this sensor provides reliable, linear velocity output across a broad range of operating conditions. The piezoelectric element generates a voltage signal directly proportional to vibration velocity, ensuring accurate dynamic measurement and early detection of potential machinery faults such as imbalance, misalignment, or bearing wear.

Constructed from stainless steel, the 330500-00-20 offers excellent mechanical strength, corrosion resistance, and long-term durability, making it suitable for harsh industrial environments including chemical plants, offshore platforms, and manufacturing facilities. Its compact dimensions (6.5×2.0×2.0 cm) and lightweight design (0.13 kg) allow flexible mounting in space-constrained areas, while the unthreaded 2-inch length simplifies integration with standard brackets or adhesive fixtures. The sensor is compatible with multiple orientations, including vertical, horizontal, or angled mounting, providing versatile installation options on machinery where conventional velocity sensors cannot fit.

The Velomitor sensor’s solid-state construction eliminates moving parts, preventing wear and maintaining consistent performance over time, even under high-vibration or temperature-cycling conditions. It operates effectively across an extended temperature range from -55°C to +121°C (-67°F to 250°F), with minimal temperature sensitivity (-14% to +7.5%), ensuring accurate readings without the need for external compensation. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, a velocity range up to 1270 mm/s (50 in/s) peak, and ±5% amplitude linearity, the sensor delivers precise, repeatable vibration data suitable for predictive maintenance and condition monitoring systems.

Applications

1.Industrial Rotating Machinery Monitoring

The 330500-00-20 sensor is ideal for high-speed rotating equipment such as turbines, motors, and centrifugal pumps. Its high sensitivity and precise velocity measurement enable early detection of mechanical anomalies, supporting predictive maintenance and minimizing unplanned downtime.

2.Harsh Environmental Installations

With a stainless steel case and extended operating temperature range, the Velomitor sensor excels in extreme environments such as chemical plants, offshore platforms, and wastewater facilities. Its compact design allows mounting in tight or confined areas while maintaining robust performance under vibration, temperature cycling, and corrosive conditions.

3.Structural and Process Equipment Vibration Analysis

The sensor is also suitable for monitoring vibrations of structural components, bearing housings, and industrial machinery frames. By providing real-time data on both low- and high-amplitude vibrations, it helps identify imbalance, misalignment, or resonance issues in production lines, processing equipment, and HVAC or refrigeration systems.
