Product Introduction

Bently Nevada 3500/22M (Part No.288055-01, with 146031-01 cable) is the upgraded Transient Data Interface (TDI) module for the 3500 machinery monitoring system. It captures transient waveform, spectrum and keyphase data of rotating machinery, and transmits raw vibration & speed data to monitoring host software. This is a new revision hardware, different from old version 138607-01. It cannot be directly interchanged with old 3500/22M due to firmware and wiring differences. It is widely used for turbine, compressor, fan and pump condition monitoring in power, petrochemical and oil & gas industry. The original manufacturer has discontinued this model.
