Product Introduction

The Bently Nevada 330750-20-CN High Temperature Velomitor Sensor is a precision vibration sensor designed to operate in high-temperature industrial environments, offering reliable performance for machinery protection and condition monitoring. Part of Bently Nevada’s Velomitor Sensor series, this model provides accurate velocity measurement of shaft vibration, ensuring safe and efficient operation of rotating equipment.

Using a piezoelectric sensing element, the 330750-20-CN converts mechanical vibration into an electrical signal proportional to velocity. Its high-temperature capability allows it to operate directly on hot machinery surfaces, making it ideal for steam turbines, compressors, and other high-temperature rotating equipment. Combined with a compatible 3300 XL Proximitor Sensor or vibration monitoring system, it delivers real-time, high-resolution vibration data crucial for predictive maintenance and protection.

The sensor is constructed with robust stainless steel housing, high-temperature insulation, and shielded cabling for resistance to electromagnetic interference (EMI) and harsh industrial conditions. Its design ensures compliance with API 670 standards, making it a reliable choice for critical industrial applications.
