The Bently Nevada 177230-02-02-05 is a loop-powered Seismic Transmitter designed for continuous overall machinery vibration monitoring. It integrates a piezoceramic shear sensing element with internal signal conditioning circuitry to process machine surface vibration into two distinct output formats: a primary 4 to 20 mA current loop proportional to velocity vibration and a secondary unbuffered dynamic acceleration voltage signal.
Configured with specific performance parameters, the Bently Nevada 177230-02-02-05 Seismic Transmitter features a full-scale velocity measurement range of 0 to 50.8 mm/s (0 to 2.0 in/s). Its primary current loop operates over a frequency bandpass of 3 Hz to 1 kHz (180 to 60 kcps) peak, providing reliable detection of low-to-mid frequency rotational flaws. The secondary dynamic signal provides raw acceleration data with a sensitivity of 10.2 mV/m/s² (100 mV/g) ±20% across a wider 2.5 Hz to 10 kHz frequency range for detailed diagnostic analysis.
The unit carries the 05 agency approval option, certifying it for deployment in hazardous areas with multiple North American and European approvals, including CSA/cNRTLus Class I Div 1/Div 2 and ATEX/IECEx Zone 0/1/2 ratings. Housed in a hermetically sealed 316L stainless steel enclosure with a top-mounted 3-pin MIL-C-5015 electrical connector, it connects directly to Programmable Logic Controllers (PLCs), Distributed Control Systems (DCS), and Supervisory Control and Data Acquisition (SCADA) platforms.
