Description

Designed for demanding industrial machinery monitoring, the Bently Nevada 330750-60 is a specialized, ruggedized High Temperature Velomitor System engineered to measure vibration velocity in extreme thermal environments. This sensor system provides accurate, reliable vibration data on gas turbines, steam turbines, and other critical high-temperature rotating machinery where standard velocity sensors fail due to ambient thermal stress.

The system utilizes a high-durability accelerometer design coupled with integrated signal processing to output a clean velocity signal. This design ensures the sensing head can withstand extreme casing temperatures while routing a low-noise signal back to a centralized machinery protection system, such as the Bently Nevada 3500 rack.

Features

• High-temperature survivability optimized for critical turbine casing monitoring.
• Direct velocity output simplifies configuration and integration with plant asset management systems.
• Hermetically sealed housing ensures protection against harsh, corrosive, and humid industrial atmospheres.
• Integrated armored cable assembly prevents mechanical wear, routing damage, and signal degradation.
• Robust electromagnetic interference (EMI) shielding to maintain signal integrity near heavy power-generation equipment.

Applications

• Gas and steam turbine casing vibration monitoring.
• Industrial exhaust fans and high-temperature blowers.
• High-temperature piping and combustion system vibration analysis.
• Power generation facilities, petrochemical plants, and heavy manufacturing refineries.

Installation Guidelines

To ensure optimal frequency response and long-term reliability, follow these key installation steps:

• Surface Preparation: Mount the sensor on a flat, clean, and smooth metal surface. Ensure the surface is free of debris, paint, or rust to allow proper mechanical coupling.
• Cable Management: Secure the integral armored cable along its run to prevent physical whip and mechanical stress. Do not exceed the minimum allowable bend radius of the conduit.
• Grounding: Maintain proper shield isolation and system grounding practices according to standard Bently Nevada wiring diagrams to prevent ground loops.
