Bently Nevada 991 Transmitters Parts

Bently Nevada 991-series thrust and vibration transmitters — two-wire loop-powered signal conditioning for axial position and vibration channels.
The 991 series is Bently Nevada's family of two-wire transmitters that condition proximity probe or vibration sensor signals into a standard loop-powered output for the plant control system. They are typically mounted close to the machine and feed axial thrust position or vibration readings to a DCS or PLC input without a full monitoring rack.
Product pages in this section record the full-scale option, electrical output and probe-system pairing encoded in each reference — the 991 numbering carries scale range, cable length and connector options, all of which must match the installed sensor for the calibration to hold. The sourcing notes flag where a transmitter is supplied as part of a calibrated probe-transmitter set.
