Quick Detail

Description

The 330500 Velomitor Piezo-velocity Sensor is a high-performance piezoelectric vibration sensor designed for industrial automation and machinery monitoring applications. Engineered to measure absolute vibration of bearing housings, machine casings, and structural components, the 330500 provides precise, real-time velocity data for predictive maintenance and condition monitoring systems. The sensor incorporates solid-state embedded electronics with no moving parts, eliminating mechanical wear and ensuring long-term stability in demanding environments.

Constructed from 316L stainless steel, the sensor is hermetically sealed for operation in 100% relative humidity and extreme temperatures from -55°C to +121°C (-67°F to +250°F). With shock survivability up to 5,000 g and amplitude linearity of ±2% to 152 mm/s (6 in/s) peak, the 330500 provides accurate readings even under severe mechanical and environmental conditions. The sensor features low base strain sensitivity (0.005 in/s/mstrain), low magnetic field susceptibility (<51 mm/s per gauss at 50 gauss), and case-isolated grounding, ensuring signal integrity in automated machinery, rotating equipment, and process control systems.

The 330500 Velomitor sensor can be mounted in any orientation—vertical, horizontal, or angled—and features a maximum mounting torque of 32–46 kg·cm (24–40 in-lb). Its dynamic output impedance below 2400 Ω allows direct integration with vibration monitoring systems, making it a reliable choice for industrial automation, condition monitoring, and high-precision equipment diagnostics.

Applications

1. Bearing Housing Vibration Monitoring
Measures absolute vibration on bearing housings in turbines, compressors, and pumps, providing early detection of misalignment, imbalance, or bearing wear.

2. Machinery Structural Health Analysis
Monitors structural vibrations on machine casings and frames, enabling predictive maintenance and reducing unplanned downtime by up to 25%.

3. Rotating Equipment Condition Monitoring
Integrated into automated systems to track velocity and detect anomalies in rotating equipment such as motors, generators, and fans.

4. High-Shock Industrial Environments
Shock survivability up to 5,000 g allows installation in machinery experiencing rapid starts, stops, or impacts, ensuring reliable vibration data.

5. Process Control and Automation Feedback
Provides precise velocity measurements for automated control systems, allowing real-time adjustments to optimize machine performance and safety.

Specifications
