Description

Configured for proximity transducer signal monitoring in the 3500 Monitoring System platform, the Bently Nevada 3500/40M-01-05 (3500/40M Proximitor Monitor) provides direct physical/electrical execution for machine displacement signal acquisition and conditioning.

Hardware Specifications

Eddy-Current Proximity Signal Processing Characteristics

The 3500/40M-01-05 Proximitor Monitor receives proximity transducer signals and transfers conditioned measurement data into the 3500 Monitoring System architecture. The module supports four-channel proximity signal acquisition through the Proximitor I/O interface with internal termination.

The module operates with eddy-current probe measurement circuits where probe scaling, target distance verification, and gap voltage validation are required during installation. A -10 VDC gap voltage target is commonly referenced when setting proximity probe operating clearance.

The input signal path supports rotor dynamics monitoring applications by processing displacement-related proximity signals from rotating machinery. Proper cable routing, shielding, and termination practices reduce electrical noise and signal cross-talk during measurement.

Field Installation Guidelines

Install the module into the designated 3500 rack position and confirm mechanical engagement before system startup. Verify that field proximity transducer wiring matches the configured input channel arrangement.

Maintain separation between proximity signal cables and high-voltage or high-current conductors. Terminate cable shields according to the monitoring system grounding practice to reduce electromagnetic interference.

Before commissioning, inspect probe wiring polarity, connector seating, and signal continuity. Verify the mechanical probe gap and confirm that the input channels correspond with the configured machine monitoring points.
