3500/70M Bently Nevada Recip Impulse Velocity Monitor Family
3500/70M
3500/70M identifies the Bently Nevada four-channel Recip Impulse Velocity Monitor model family. 3500/70M is used in reciprocating-compressor solutions to monitor crankcase and crosshead vibration from compatible seismic inputs. Configurable functions include impulse acceleration, Acceleration 2, reciprocating velocity, and low-frequency reciprocating velocity. This record does not select the AA I/O-module option or BB approval option in 3500/70M-AA-BB and does not assign an exact main-module or I/O spare part number.
Scope note: 3500/70M does not select an I/O or output option, approval suffix, exact front-module spare, or exact rear-module spare. Content must remain at model/family level until an exact order code or nameplate is available.
