Tag: Bently Nevada- 990-05-XX-01-00

Product Description​​

The​​Bently Nevada 990-05-XX-01-00​​is a high-performance vibration transmitter designed for continuous monitoring of rotating machinery in critical industrial applications.This robust transmitter converts raw vibration signals from proximity probes into standardized 4-20mA outputs for machinery protection systems.Engineered for reliability in demanding environments,it provides essential condition monitoring for pumps,compressors,turbines,and other vital rotating assets.

​​Application Scenarios​​

In a natural gas compressor station,multiple​​Bently Nevada 990-05-XX-01-00​​vibration transmitters monitor critical bearing vibrations on high-pressure centrifugal compressors.Each transmitter processes signals from XY proximity probes measuring shaft relative vibration,providing real-time 4-20mA outputs to the control system.When a compressor blade imbalance develops due to fouling,the​​990-05-XX-01-00​​detects the increasing vibration levels and triggers alarms at predetermined setpoints.The early warning allows operators to schedule maintenance before catastrophic failure occurs,preventing unplanned shutdowns that could disrupt gas pipeline operations.The transmitter’s robust design withstands the high-temperature and high-vibration environment typical of compressor installations.

​​Technical Principles and Innovative Values​​

​​Innovation Point 1:Advanced Signal Conditioning Technology.​​The​​Bently Nevada 990-05-XX-01-00​​incorporates sophisticated signal processing that converts the raw AC vibration signal from proximity probes into a true peak-to-peak DC representation.This processing includes automatic temperature compensation and filtering to eliminate electrical noise,ensuring accurate vibration measurement unaffected by environmental conditions.The transmitter maintains calibration stability over extended periods,reducing maintenance requirements.

​​Innovation Point 2:Dual Alarm Setpoint Configuration.​​Each transmitter features independently adjustable alarm and danger setpoints with dedicated relay outputs.This dual-threshold design enables staged response to deteriorating machinery conditions,providing early warning alerts for maintenance planning while maintaining immediate shutdown capability for critical protection.The setpoints are easily configured via front-accessible potentiometers with clear visual indicators.

​​Innovation Point 3:Robust Environmental Protection.​​Designed for harsh industrial environments,the transmitter housing provides exceptional protection against moisture,dust,and corrosive atmospheres.The design includes electrical isolation and surge protection to ensure reliable operation in areas with significant electrical noise and transient voltages common in industrial settings.
