The Bently Nevada Vibration Transmitter 990-04-50-01-CN  is a vibration transmitter primarily designed for original equipment manufacturers of centrifugal air compressors, small pumps, motors, or fans. It provides a simple 4 to 20 mA proportional vibration signal, allowing direct integration with machinery control systems for effective monitoring and protection. This PLC Controller 990-04-50-01-CN Bently Nevada, loop-powered device accepts input from 3300 NSv proximity probes along with matching extension cables, available in 5 m and 7 m lengths, ensuring flexibility in installation and system design.

The 990-04-50-01-CN Bently Nevada vibration transmitter conditions the input signal into peak-to-peak vibration amplitude engineering units and converts it into an industry-standard 4 to 20 mA output. This allows the control system to perform machinery protection functions such as alarming, monitoring, and logical interlocks. Its integrated Proximitor Sensor eliminates the need for an external unit, simplifying system setup and reducing installation complexity.

Equipped with non-isolated PROX OUT and COM terminals, along with a coaxial connector, the Vibration monitoring transmitter Bently Nevada 990-04-50-01-CN provides dynamic vibration and gap voltage signals for diagnostic purposes. It also features non-interacting zero and span potentiometers for easy loop adjustments and a Test Input pin for quick verification of signal output.

Durability and reliability are further enhanced with a Not OK/Signal Defeat circuit to prevent false alarms caused by faulty proximity probes or loose connections. The Bently Nevada 990-04-50-01-CN 2-Wire Vibration Transmitter supports flexible mounting options, including DIN-rail clips or bulkhead screws, and comes in a compact, lightweight design at 10 cm x 7.5 cm x 5.2 cm and 0.44 kg, making it ideal for critical machinery monitoring applications.
