Bently Nevada 177230-02-02-05 177230 Series Integrated Vibration Transmitter

Bently Nevada 177230-02-02-05 is a member of the 177230 Series Integrated Vibration Transmitter family. Designed for continuous machine monitoring, this 2-wire loop-powered transmitter provides a direct 4-20 mA output proportional to vibration amplitude. It is an ideal solution for critical machinery protection in industrial environments such as oil & gas, power generation, and chemical processing.

By combining a piezoelectric accelerometer with signal conditioning electronics into a single housing, the 177230 Series eliminates the need for external signal conditioners or rack-mounted monitoring systems, reducing installation costs and complexity.

Key Features

Integrated Design: Combines sensor, signal conditioning, and 4-20 mA transmitter in one compact unit.

Loop-Powered: 2-wire design operating at 12-28 VDC.

Output: Standard 4-20 mA signal proportional to vibration velocity or displacement.

Housing: Stainless steel construction for durability in harsh industrial environments.

Mounting: Standard 1/4-28 UNF threaded mounting stud for direct installation on machinery cases.

Installation Considerations

To ensure optimal performance:

Surface Preparation: Mount on a clean, flat, unpainted surface directly on the machine bearing housing.

Cable Routing: Use shielded twisted-pair cable to minimize electrical noise interference.

Power Supply: Ensure the loop power supply provides adequate voltage (min 12 VDC at transmitter terminals).

Calibration: Verify full-scale range matches the application’s expected vibration levels to avoid signal clipping.
