The Bently Nevada 990-05-XX-01-00 MOD:147202-01 Vibration Transmitter is specifically designed for original equipment manufacturers (OEMs) of centrifugal air compressors, pumps, motors, and fans that require a simple and dependable vibration monitoring solution. It converts machinery vibration into a standard 4–20 mA proportional output, making it ideal for direct connection to PLC, DCS systems, or other machinery control platforms.
This model features a full-scale range of 0–5 mils peak-to-peak (0–125 μm pp) and supports a wide frequency response from 5 Hz to 6,000 Hz (+0, -3 dB), ensuring accurate vibration measurement across typical rotating equipment operating conditions. The prox output linear range of 1.4 mm (55 mils) begins at approximately 0.25 mm (10 mils) from the target surface, delivering stable and repeatable readings.
An important advantage of this transmitter is the integrated Proximitor® sensor, which eliminates the need for an external proximitor unit. This integration reduces wiring complexity, lowers installation costs, and improves overall system reliability. The unit is designed for 35 mm DIN rail mounting, allowing fast and secure installation in standard control cabinets.
For machinery protection and system safety, the 990 transmitter includes a NOT OK / signal defeat function. Under a fault condition, the output signal drops below 3.6 mA within 100 microseconds, clearly indicating an abnormal status to the control system, and automatically recovers within 2–3 seconds once the condition is cleared. With its robust design and proven Bently Nevada performance, this transmitter is a trusted solution for continuous vibration monitoring in OEM and industrial environments.
