Bently Nevada 330525-10 Velomitor XA Piezo-velocity Sensor

Description

The 330525-10 Velomitor XA (eXtended Application) Piezo-velocity sensor is a robust, industrial-grade transducer engineered by Bently Nevada for machinery casing vibration monitoring. This sensor is a ruggedized iteration of the standard 330500 Velomitor, designed specifically for harsh operating environments where a traditional sensor housing may not be practical. It features a 316L stainless steel case and a weatherproof, Mil-C-26482 connector, allowing for direct installation without a housing while maintaining IP-65 and NEMA 4X compliance when installed with a properly mating extension cable.

This transducer is used to monitor casing vibration on rotating machinery, translating vibration levels into a proportional voltage signal for analysis. The 330525-10 model is intended for applications requiring high durability and resistance to moisture. Its frequency response and sensitivity are optimized for standard bearing housing measurements, effectively capturing machine malfunctions such as imbalance and misalignment by transmitting rotor vibration transmitted to the machine casing.

Features

• 316L stainless steel housing for superior corrosion resistance and durability in harsh environments
• Weatherproof Mil-C-26482 connector assembly designed for moisture resistance
• Designed to meet IP-65 and NEMA 4X requirements when properly installed with compatible extension cables
• Resonant frequency greater than 12 kHz, ensuring accurate signal capture within the specified bandwidth
• Sensitivity of 3.94 mV/mm/s (100 mV/in/s) for precise signal output
• Broad operating temperature range from -55 degC to +121 degC

Applications

• Casing vibration measurement on rotating machinery such as pumps, fans, and compressors
• Harsh or moist environments where standard housings are not installed
• Machinery protection systems requiring overall casing vibration monitoring

Installation Guidelines

Ensure the sensor is mounted securely using the specified torque of 45 N-m. When installing in moist environments, ensure that a mating extension cable is used to maintain the IP-65/NEMA 4X protection rating. Use care during installation to prevent generating signals that do not represent actual machine vibration, as improper mounting can alter amplitude and frequency response. Ensure the sensor is connected to a proper monitoring system that supports the 100 mV/in/s sensitivity profile.

Compliance and Certifications

This sensor is designed for compliance with various hazardous area standards, including CSA/NRTL/C, ATEX, and IECEx certifications. Please verify the specific approval markings on the device label for the 330525-10 configuration.
