Bently Nevada 990-04-70-01-CN Vibration Transmitter – 3300 XL Series
When a critical rotating machine — a turbine, compressor, or pump — loses its vibration monitoring capability, the consequences are immediate and severe. Without a functioning vibration transmitter, your condition monitoring system goes blind. Undetected imbalance, misalignment, or bearing wear can escalate within hours into catastrophic mechanical failure, unplanned downtime, and six-figure repair costs. The Bently Nevada 990-04-70-01-CN is the precision instrument that keeps your machinery protection system fully operational and your plant running safely.
The 990-04-70-01-CN is a field-proven vibration transmitter within Bently Nevada’s renowned 3300 XL Series — the global standard for machinery protection in oil & gas, power generation, and heavy industry. This specific configuration (4–20 mA output, 70 mil range, standard connector, CN suffix for regional compliance) occupies a critical niche in the 3300 ecosystem: it bridges proximity probe signals into standard DCS/PLC 4–20 mA inputs, enabling seamless integration with virtually any modern control architecture without requiring a dedicated Bently Nevada monitoring rack.
