990-04-XX-01-01 | Bently Nevada | MOD:165335-01 990 Vibration Transmitter

### Product Description
The 990-04-XX-01-01 is a rack-mounted vibration transmitter module designed for integration into Bently Nevada 990 Series monitoring systems.
Moreover, it converts proximity probe signals into standardized 4–20 mA outputs for continuous machinery health assessment in critical rotating equipment.
Therefore, it supports real-time vibration monitoring in turbomachinery, compressors, and large motors where high-reliability signal conditioning is required.

### Technical Specifications

### Typical Applications
– Gas turbine and steam turbine vibration monitoring in power generation plants
– Centrifugal compressor monitoring in oil and gas refineries
– Critical pump and fan vibration surveillance in chemical processing facilities
– Turboexpander condition monitoring in natural gas processing

### FAQ
What input signal does this transmitter accept?
It accepts differential AC voltage signals from Bently Nevada 3300 or 3500 series proximity probes.

Is the module hot-swappable?
Yes, it supports hot-swap operation within compatible 990 Series racks without system shutdown.

Does it support dual-channel configuration?
No, this is a single-channel transmitter; dual-channel capability requires two separate modules.

What is the output signal range?
Standard output is 4–20 mA proportional to vibration velocity or displacement, configurable via front-panel switches.

Is calibration traceable to NIST standards?
Factory calibration is performed per ISO 17025-accredited procedures, with documentation available upon request.
