Product function
Proximity Sensing: Converts eddy-current probe signals into shaft-position and clearance data using the Bently Nevada 3701/60 175794-01.
Vibration Detection: Calculates overall vibration velocity and provides narrow-band amplitudes (1×, 2×) for balance and fault analysis via the Bently Nevada 3701/60 175794-01.
Alarm/Trip Outputs: Reports alarm conditions to the rack’s digital I/O or host controller for fault-response (alert, shutdown).
Diagnostics: Onboard self-test with probe-plug detection and sensor-fault flagging in Bently Nevada 3701/60 175794-01, communicated to the rack controller.
Core Supporting Modules
3701/00 Rack Chassis: Houses up to 16 modules including the Bently Nevada 3701/60 175794-01, provides 24 V DC power and backplane data bus.
3701/90 CPU Module: Interfaces modules to host systems; configures setpoints, collects data, communicates via Modbus/PROFIBUS.
3701/50 Relay Module: Provides form C relay outputs for alarm/trip signals.
3701/70 Analog Output Module: Converts vibration and proximity measurements to 4-20 mA loops for external controllers.
