Description

The 3500/40M Proximitor Monitor is a four-channel vibration and position monitoring module for Bently Nevada™ 3500 automation racks. The 3500/40M Proximitor Monitor accepts 1 to 4 proximity transducer inputs and conditions signals for radial vibration, thrust position, differential expansion, eccentricity, and REBAM measurements. Each channel of the 3500/40M Proximitor Monitor compares real-time values against user-defined Alert and Danger setpoints to drive automated alarm and trip outputs.

The 3500/40M Proximitor Monitor operates with 7.7 W typical power consumption and fits one full-height rear slot. Sensitivity options include 3.94 mV/μm (100 mV/mil) or 7.87 mV/μm (200 mV/mil), enabling precise displacement scaling. Amplitude accuracy is within ±0.33% of full scale typical (±1% maximum), with phase error up to 3 degrees. Frequency response is user-programmable from 0.002 Hz to 8678 Hz depending on filter selection, supporting rotor, spike, gap, and 1X vector analysis. Operating range -30°C to +65°C and 95% non-condensing humidity allows the 3500/40M Proximitor Monitor to deliver continuous machine protection and automated condition monitoring in turbine and compressor control systems.

Applications

Measure Radial Vibration from 0.108 Hz to 2221 Hz for Rotor Protection

The 3500/40M Proximitor Monitor accepts up to four proximity probe inputs and processes radial vibration with programmable rotor filter response from 0.108 Hz to 2221 Hz. With sensitivity options of 3.94 mV/μm or 7.87 mV/μm, the 3500/40M Proximitor Monitor converts shaft displacement into precise voltage signals. Amplitude accuracy within ±0.33% of full scale typical allows the 3500/40M Proximitor Monitor to trigger alarm outputs when vibration exceeds defined micrometer thresholds in turbine and compressor automation systems.

Monitor Thrust Position with ±1 Percent Full Scale Accuracy

The 3500/40M Proximitor Monitor measures axial displacement using 3.94 mV/μm or 7.87 mV/μm scaling and compares values to programmable Alert and Danger setpoints. Alarm setpoint accuracy within 0.13% of the desired value enables the 3500/40M Proximitor Monitor to drive shutdown logic before thrust movement reaches mechanical limits.

Detect Shaft Eccentricity and 1X Vector Phase Within 3 Degrees

The 3500/40M Proximitor Monitor performs 1X and 2X vector calculations with phase error up to 3 degrees. For machines below 30000 cpm, Not 1X accuracy is ±3%, allowing the 3500/40M Proximitor Monitor to identify imbalance or misalignment conditions and activate automated protection outputs.

Track Differential Expansion Using Gap Response Down to 0.002 Hz

With gap frequency response programmable from 0.002 Hz to 1.0 Hz, the 3500/40M Proximitor Monitor captures slow thermal growth in turbines. The 3500/40M Proximitor Monitor processes these low-frequency signals to initiate alarm relays when casing-to-rotor expansion approaches configured limits.
