The Bently Nevada 177230-01-02-00 is a simple, loop-powered seismic transmitter designed to integrate vibration monitoring directly into programmable logic controllers (PLCs), distributed control systems (DCS), or SCADA platforms. The 177230-01-02-00 measures overall casing vibration and provides a primary 4 to 20 mA loop-powered output signal proportional to peak vibration, alongside an unbuffered dynamic acceleration signal for detailed diagnostic analysis. Constructed with a 316L stainless steel housing and a ceramic shear sensing element, it delivers continuous vibration monitoring for plant asset condition monitoring and predictive maintenance.
