102550-01 | Bently Nevada | Proximity Transducer System

Product Overview

The Bently Nevada 102550-01 functions as a high-precision Eddy Current Proximity Transducer designed for critical machinery protection. It measures static (gap) and dynamic (vibration) distances between the probe tip and a conductive target. This sensor serves as a primary tool for monitoring radial vibration, axial thrust, and shaft position in high-speed rotating equipment such as turbines, compressors, and motors. We supply this unit as 100% Brand New Original stock to ensure maximum measurement accuracy and system longevity.

Technical Specifications

The 102550-01 delivers linear voltage output directly proportional to the distance from the target material:

Engineering Advantages

• High-Frequency Signal Capture: The 10 kHz frequency response allows the transducer to capture rapid shaft vibrations and sub-synchronous instabilities. This capability ensures that the monitoring system identifies mechanical faults, such as oil whirl or whip, before they escalate into catastrophic failures.

• Ruggedized Environmental Resistance: The transducer operates reliably between -35°C and +80°C. This wide thermal range enables installation in harsh industrial environments, including unheated turbine halls or locations adjacent to steam-driven machinery.

• Simplified Calibration Alignment: The linear voltage output simplifies the gapping process during installation. Maintenance teams utilize the 24 VDC power supply to set the "center-point" voltage, ensuring the sensor operates within its optimal 0-2 mm linear range for maximum sensitivity.

• Electromagnetic Interference (EMI) Shielding: The internal circuitry rejects common-mode noise and electrical interference typically found in industrial motor control centers. This shielding prevents false "alert" or "danger" trips in the machine protection system.

• Compact Housing for Restricted Access: The 120 mm x 25 mm form factor facilitates mounting in tight bearing housings. This compact design allows engineers to position the probe as close to the bearing face as possible, minimizing the influence of shaft runout.

FAQs

• How do I determine the correct gap for the 102550-01 during installation?

  You must use a digital multimeter to monitor the voltage output while adjusting the probe depth. Typically, you aim for a specific negative voltage (e.g., -10 VDC) that corresponds to the middle of the 0-2 mm linear range, depending on your specific Proximitor® calibration.

• Does this sensor require a specific Proximitor® or Driver?

  Yes. The 102550-01 works as part of a system. You must pair it with a compatible Bently Nevada Proximitor® calibrated for the specific target material (usually 4140 steel) and cable length to maintain measurement linearity.

• What indicates a failure in the 102550-01 transducer?

  A "Not OK" status on your monitoring rack or a steady-state voltage output that does not change with distance usually indicates a probe fault. Always check the probe tip for physical damage or carbon buildup, as these factors interfere with the eddy current field.

• Is this a refurbished or surplus unit?

  No. We guarantee that this 102550-01 is 100% Brand New Original. We do not sell refurbished parts for machine protection systems, as used transducers cannot guarantee the signal integrity required for safety-critical monitoring.
