124534-01 | Bently Nevada | Proximitor Sensor Module

Product Overview

The Bently Nevada 124534-01 functions as a high-precision Eddy Current Proximitor module within the Bently Nevada transducer system. This electronic signal conditioner converts the complex impedance change of a proximity probe into a linear DC voltage directly proportional to the gap between the probe tip and the target material. It provides the core data necessary for radial vibration, axial thrust, and shaft position monitoring in high-speed turbomachinery. We supply this unit as 100% Brand New Original equipment, offering a critical solution for maintaining legacy protection systems where the manufacturer has ceased production.

Technical Specifications

The 124534-01 utilizes specialized circuitry to maintain a linear sensitivity of 200 mV/mil across the specified measurement window:

Engineering Advantages

• Linear Signal Conversion: The 124534-01 ensures a constant 200mV/mil output throughout the 10-90 mil range. This precision eliminates non-linearities in the vibration data, allowing the monitor rack to calculate exact shaft displacement without signal distortion.

• Active Grounding & Shielding: The module’s internal design rejects electromagnetic interference (EMI) and radio frequency interference (RFI). This allows for reliable signal transmission even when routed through industrial environments saturated with high-voltage equipment and motor drives.

• Simplified Calibration Alignment: The Proximitor facilitates rapid "gapping" of sensors. By monitoring the output voltage during installation, technicians set the probe at the optimal 50-mil center point (-10 VDC), ensuring the sensor operates within its most accurate measurement zone.

• Ruggedized DIN Rail Housing: The 0.75 lbs aluminum housing provides physical protection and excellent thermal dissipation. The secure mounting mechanism resists mechanical vibrations, preventing intermittent signal loss in high-stress turbine hall environments.

• Legacy System Continuity: As a "Discontinued by Manufacturer" item, our Brand New Original 124534-01 stock prevents the need for costly system retrofits. It integrates seamlessly into existing 3300 or 3500 series racks without requiring hardware modifications or software re-scaling.

FAQs

• Can I use the 124534-01 with any proximity probe?

  No. This Proximitor specifically matches the electrical characteristics of a designated Bently Nevada probe and cable length combination (typically 5-meter or 9-meter systems). Always verify your probe part number to ensure impedance matching and sensitivity accuracy.

• Does this module require a separate power supply?

  The 124534-01 draws its 24VDC power directly from the Bently Nevada monitoring rack (e.g., the 3500/15 power supply) or an equivalent high-stability industrial power source.

• How does this unit handle target material variations?

  This Proximitor is factory-calibrated for AISI 4140 steel. If your shaft utilizes different metallurgy, you must apply a correction factor to the output or utilize a Proximitor calibrated specifically for that material to maintain the 200mV/mil sensitivity.

• Is this a refurbished or surplus unit?

  We guarantee this unit is 100% Brand New Original. In machinery protection, using refurbished sensors is a high-risk practice; only new components provide the guaranteed MTBF (Mean Time Between Failures) required for SIL-rated safety loops.
