Bently Nevada 990-05-XX-03-05 Vibration Transmitter

Overview

The Bently Nevada 990-05-XX-03-05 Vibration Transmitter belongs to the 990 series of loop-powered vibration transmitters, engineered to provide reliable, proportional vibration output for smaller rotating machinery, such as compressors, pumps, motors, and fans. It delivers a 4–20 mA signal proportional to vibration amplitude, making it ideal for machinery monitoring, trending, and alarm integration within industrial control systems. 

This transmitter integrates a Proximitor Sensor within a compact, rugged, potting-protected housing, eliminating the need for an external sensor and simplifying installation in tight spaces. It is commonly paired with Bently Nevada 3300 NSv proximity probes and extension cables for seamless system compatibility. 

Industrial Performance & Features

• Loop-Powered 4–20 mA Output: Supplies proportional vibration level signals directly to PLCs or control systems with standard industrial current loop communications. 

• Integrated Proximitor Sensor: No external unit required; reduces wiring and installation complexity. 

• Zero & Span Adjustments: External potentiometers allow easy signal calibration on site. 

• NOT OK / Signal Defeat Circuit: Prevents false high outputs when a fault or loose connection is detected. 

• DIN Rail or Bulkhead Mounting Options: Provides flexibility for panel or rack installations. 

• Potted Construction: Designed to withstand high humidity and industrial conditions without performance degradation. 

Typical Industrial Applications

The 990-05-XX-03-05 Vibration Transmitter is widely deployed for condition monitoring in industries where early detection of vibration anomalies is essential to prevent equipment failure and unplanned downtime, such as:

• Centrifugal compressors

• Industrial pumps and blowers

• Electric motors and gearboxes

• Fans in HVAC and process systems

• OEM machinery with integrated monitoring needs

  Its compact, loop-powered design makes it especially suitable for OEM installations and systems with limited cabinet space. 

By converting proximity probe data into a standard industry signal, the 990 transmitter enables predictive maintenance, alarm activation, and trend analysis across a range of machinery types, supporting reliability programs and maintenance decision workflows.
