Product Overview

The 990-04-XX-01-00 (147202-01) is an integrated vibration transmitter designed for continuous machinery protection. Engineered by Bently Nevada, this device simplifies the interface between proximity probes and control systems by converting eddy current sensor signals directly into a linearized 4–20 mA output. This eliminates the need for a separate Proximitor unit, making the 990-04-XX-01-00 (147202-01) an ideal solution for OEMs and industrial operators seeking a cost-effective, high-reliability method to monitor radial vibration in compressors, pumps, and motors. Its robust design is specifically tuned for use with the 3300 NSv proximity probe system, ensuring high-fidelity data acquisition in compact or hazardous industrial environments.
