990-05-XX-01-00 MOD：167577-07 Bently Nevada Vibration Transmitter
Description
The 990‑05‑XX‑01‑00 belongs to the 990 series of vibration transmitters from Bently Nevada — designed to accept a compatible proximity probe (e.g. a 3300 NSv / XL eddy‑current probe + extension cable) and output an industrial‑standard 4–20 mA analog
signal proportional to vibration amplitude (peak‑to‑peak).It is a 2‑wire, loop‑powered transmitter, meaning only two conductors are required to power the unit and carry the 4–20 mA output.Physically, the transmitter housing
is compact and robust (commonly with stainless‑steel enclosure and potted construction for environmental resistance).In short: 990‑05‑XX‑01‑00 is not a standalone vibration sensor, but a signal
conditioner / transmitter that—when used with a compatible proximity probe + cable—provides a user‑friendly analog
output for vibration monitoring or machine protection logic.

FAQ |
What do I need to make it work (or what else must I buy)?You need a compatible non‑contacting proximity probe (e.g. 3300 NSv / XL) plus an extension cable, arranged with correct gap to the metallic target (shaft, etc.). The 990 transmitter then conditions that probe signal into a 4–20 mA output for your control / monitoring system. Without a proximity probe + cable, the transmitter alone does nothing useful. |
What kind of measurement does it output? Static position? Vibration?Primarily — it outputs vibration amplitude (peak‑to‑peak). The 4–20 mA loop represents the vibration magnitude as detected by the proximity probe. Additionally: via the “PROX OUT” coaxial connector (non-isolated), you can access the raw probe signal (gap + dynamic component) to perform diagnostics or further analyses — if you provide suitable isolation or use battery‑powered measuring gear. |
What are the typical applications / use cases for 990‑05‑XX‑01‑00?It is widely used by OEMs and operators of small‑to‑medium rotating machinery — such as centrifugal compressors, pumps, motors, fans — where a simple analog vibration output (rather than full-spectrum analysis) is sufficient, and where space or cost constraints make a compact loop‑powered transmitter attractive.It is especially suitable for machine‑protection logic, basic vibration trending, and preventive‑maintenance systems integrated into DCS / PLC systems. |
