Bently Nevada 177230-01-02-05 177230 Series Integrated Vibration Transmitter

 Bently Nevada 177230-01-02-05 is a high-performance seismic transmitter from the trusted 177230 Series Integrated Vibration Transmitter family. Manufactured by Bently Nevada (a Baker Hughes brand), this loop-powered 2-wire device provides a standard 4-20 mA output signal proportional to vibration velocity, making it an ideal solution for continuous machinery condition monitoring in critical industrial applications.

Designed for simplicity and reliability, the 177230 Series combines a piezoelectric accelerometer with integrated signal conditioning electronics into a single, compact housing. This integrated design eliminates the need for external signal conditioners or rack-mounted monitoring systems, significantly reducing installation costs, complexity, and maintenance requirements .

Key Features

Integrated Design: Combines sensor, signal conditioning, and 4-20 mA transmitter in one compact unit—no separate proximitor required 

Loop-Powered: Simple 2-wire installation with 12-35 VDC operating voltage 

Standardized Output: 4-20 mA signal directly interfaces with PLC, DCS, and SCADA systems 

Wide Frequency Response: 3 Hz to 1 kHz (180 to 60,000 CPM) captures critical vibration signatures including imbalance, misalignment, and looseness 

Rugged Construction: 316L stainless steel housing with IP65 protection rating for harsh industrial environments 

Global Certifications: Multiple approvals including CSA/NRTL/C, ATEX, and IECEx for hazardous area deployment 

No Field Configuration: Simple installation with factory-preset calibration—no on-site setup required
