177230-01-02-05 Bently Nevada Vibration Sensor -40°C To +85°C
IP66/IP67
Product Overview
**The 177230-01-02-05** is a high-performance configuration version
of the Bently Nevada 177230 series vibration monitor, specifically
designed for the condition monitoring and protection of rotating
machinery. This product utilizes advanced piezoelectric vibration
sensing technology to convert mechanical vibration signals into a
standard 4-20mA current output or digital signal, allowing direct
connection to DCS, PLC, or SCADA systems for continuous online
monitoring of critical equipment such as turbines, compressors,
pumps, and fans. With its high precision, high reliability, and
adaptability to harsh environments, the 177230-01-02-05 has become
a core sensing element in preventative maintenance systems in
industries such as petrochemicals, power, metallurgy, and
papermaking.

Typical Application Scenarios
Petrochemical Industry Compressor Monitoring
**Application**: Shaft vibration monitoring of large centrifugal
compressors
**Solution**: 177230-01-02-05 Installed in the compressor bearing
housing, HART signal connected to DCS. Remote configuration via AMS
software, automatically switching ranges according to load (10-50Hz
low-speed mode / 10-1000Hz normal mode). Intrinsically safe design
allows direct installation in hydrogen compressor areas without an
explosion-proof enclosure, saving 40% in costs.
Steam Turbine Protection in Thermal Power Plants
**Application**: Steam Turbine TSI (Steam Turbine Monitoring
Instrument) System
**Solution**: Each bearing is equipped with a bidirectional X/Y
177230 sensor. A 4-20mA signal is sent to the PLC to implement
protection logic. HART communication uploads data to the Entek
Enwatch system for long-term trend analysis. Maintenance-free
operation over a 20-year lifespan, reducing downtime for
maintenance.
