The GE Bently Nevada 177230 Seismic Transmitter provides a 4-20 mA signal proportional to the 0-1 inch/sec 0-pk velocity movement of a roller element bearing housing or machinery housing. It is designed for use on non-critical machines. The transmitter automatically integrates the acceleration signal on the machine to vibration prior to sending the signal to the controller. The Seismic Transmitter also has a dynamic acceleration waveform output for advanced diagnostics that is accessible at the non-sensor end of the field wiring through either a patch panel or some other wiring technique.
The GE Bently Nevada 177230 Seismic Transmitter combines a reliable design with ease of installation and maintenance which to reduce training and service costs. When integrated into the PLC or controls system of an overall plant asset condition monitoring solution, the transducer will help users better manage downtime, optimize maintenance planning, and avoid unforeseen catastrophic failures of machinery assets.
| GE Bently Nevada 177230 Seismic Transmitter specifications: | |
|---|---|
| Electrical | |
| Sensitivity – Main loop (Signal One) | 0.0 to 25.4 mm/s (0 to 1.0 in/s) ± 10%, broadband rms |
| Output Format, Pin A Referenced to Pin B | 4 to 20 mA current loop Velocity vibration |
| Excitation Voltage | 12 to 30 Vdc (current limited to 40 mA). Note: This product is for use with PLCs, DCS and SCADA systems that have internal power supply that are typically current limited in the range of 30 mA to 35 mA |
| Settling Time | Less than 15 seconds within 2% of final value |
| Connector Wiring Convention | Pin A: 4-20 mA Positive Loop Pin B: 4-20 mA Negative Loop and common for Dynamic Signal Pin C: Dynamic Signal in voltage, unbuffered |
| Frequency Response | 10 Hz to 1 kHz (600 cpm to 60 kcpm) ± 10% |
| Sensitivity – Dynamic Signal (Signal Two) | 10.2 mV/m/s2 (100 mV/g) ± 5% |
