Bently Nevada 21505-00-60-10-02 – Proximity Signal Conditioner | 3500 Series Platform
Engineering Background: The Bently Nevada 3500 Series is the industry benchmark for continuous machinery protection in rotating equipment applications. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the 3500 platform delivers real-time vibration, position, and speed monitoring with SIL-rated reliability.
Product Positioning: The 21505-00-60-10-02 is a dedicated signal conditioner module within the 3500 Series ecosystem. It conditions raw proximity transducer signals—converting eddy-current sensor outputs into clean, calibrated DC voltage or current signals suitable for the 3500 monitor rack. This module is essential for accurate shaft displacement and radial vibration measurement in turbines, compressors, pumps, and motors.

System Architecture & Signal Flow
The 21505-00-60-10-02 sits between the proximity transducer (sensor + extension cable + oscillator/demodulator) and the 3500 monitor module. Signal flow:
- Proximity Probe (e.g., 3300 XL 8mm) detects shaft gap via eddy-current effect.
- Oscillator/Demodulator converts the impedance change to a raw DC voltage.
- 21505-00-60-10-02 Signal Conditioner buffers, scales, and conditions the signal for the rack monitor input.
- 3500 Monitor Module processes the conditioned signal for alarm, trip, and data acquisition functions.
- 3500 Communication Gateway transmits data to DCS / SCADA / historian systems.
