Applications

Petrochemical: Bently Nevada 330750-80-05 is used for vibration monitoring of high-temperature reactors, cracking furnaces, and other equipment, promptly detecting structural deformation or loose components caused by high temperature and high pressure.

Energy and Power: Bently Nevada 330750-80-05 is used for monitors the vibration of steam turbines and generators operating at high temperatures to prevent equipment failures caused by abnormal vibration.

Steel and Metallurgy: Bently Nevada 330750-80-05 is used for installed on high-temperature blast furnaces, converters, and other equipment, it provides real-time monitoring of equipment vibration status and provides data support for equipment maintenance.

Installation Requirements

Location Requirements: The sensor must be mounted on the bearing housing or machine casing. Improper installation may result in reduced amplitude and frequency response or produce erroneous signals that do not represent actual vibration.

High Temperature Precautions: In environments exceeding +400°C, ensure the electronics are away from heat sources (e.g., in areas below +100°C). Secure the cable to prevent bending or mechanical damage.

Professional Support: Bently Nevada provides engineering services to assist with measurement and installation.

Cable Installation: For the 80-foot cable of the 330750-80-05, plan the route to avoid interference.
