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

Features Part number 177230-02 Manufactured by GE Bently Nevada Ease of implementation and use Interfaces with PLCs and control systems ( like DCS and SCADA) Provides a quick learning curve for operations and maintenance Requires no field configuration or adjustments Needs few additional parts for a complete system Includes self-test Incorporates protected interface Supports a variety of interface cables Data Quality Provides accurate and repeatable data Uses simple data format Provides raw vibration signal for verification and analysis EHS Compliant Implements safe and ergonomic design Supports access to hazardous areas Incorporates robust CM design for reliability Implements Industry standard 4 to 20mA loop-powered transmitter 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% Output Format, Pin C Referenced to Pin B Voltage, Acceleration vibration. Note: The Dynamic Signal Negative ( Pin B) requires isolation from any grounding. If this terminal is grounded, the 4-20 mA loop will short, resulting in no output Frequency Response 2.5 Hz to 10 kHz ( 150 cpm to 600 kcpm) ± 10% Linearity ± 1% Output Bias Referenced to Pin B 2.5 V ± 0.1 V Full Scale Range 196m/ s2 ( 20 g' s) peak Velocity Range 420 mm/ s ( 16.5 in/ s) peak Mounted Resonant Frequency Greater than 12 kHz Transverse Sensitivity Less than 5% of sensitivity Sensing Element Type Ceramic / Shear Environmental Limits Operating Temperature Range -40 ° C to + 85 ° C ( -40 ° F to + 185 ° F) Electrical Isolation Greater than 108 ohms Isolation Breakdown Voltage 600 Vrms with less then 1 mA leakage current Shock Survivability 9.810 m/ s2 ( 1.000 g peak) , maximum drop test Magnetic Field Sensitivity Less than 20 ¼ m/ s/ gauss ( 790 ¼ in/ s/ gauss) peak Less than 14.7 mm/ s2/ gauss ( 150 ¼ g/ gauss) peak Physical Case Material 304L stainless steel Connector 3-pin MIL-C-5015, stainless steel Mounting Hole in Body 1/ 4-28 UNF Mounting Threads 3/ 8-24 UNF 1/ 4-18 NPT 1/ 4-28 UNF Connector Wiring Convention Pin A: 4-20 mA Loop Power ( Positive with reference to Pin B) Pin B: 4-20 mA Loop Return ( Negative/ return for Dynamic Signal) Pin C: Dynamic Signal ( Unbuffered, referenced to Pin B)
