The Bently nevada 990-05-50-02-01 SERIES 2-WIRE vibration transmitter is engineered specifically for OEM applications, such as centrifugal air compressors, small pumps, motors, or fans. It provides a simple, reliable 4 to 20 mA vibration signal that integrates seamlessly into existing machinery control systems. Designed as a two-wire, loop-powered device, the VIBRATION TRANSMITTER Bently Nevada 990-05-50-02-01 accepts input from the trusted 3300 NSv proximity probe and matching extension cable, supporting system lengths up to 5.0 metres (16.4 feet). This transmitter ensures critical equipment receives continuous vibration monitoring for effective operational protection.

The 990-05-50-02-01 2-Wire Vibration Transmitter processes incoming signals and converts them into precise peak-to-peak vibration measurements, delivering these as industry-standard 4 to 20 mA outputs directly to the control system. This eliminates the need for separate Proximitor sensors, as it features an integrated conditioning circuit. It also supports bulkhead screw mounting for easy installation and carries CSA Division 2 certification, making it suitable for various industrial settings.

Key features of the Bently Nevada 990-05-50-02-01 PDF include non-interacting zero and span adjustments located beneath the transmitter label for straightforward loop calibration, plus a test input pin that allows quick verification of output signals using a function generator. Its built-in Not OK/Signal Defeat circuit intelligently prevents false alarms or high outputs caused by faulty probes or loose connections, thus enhancing system reliability.

Additionally, the 990 Vibration Transmitter Bently Nevada offers non-isolated “PROX OUT” and “COM” terminals along with a coaxial connector that supplies dynamic vibration and gap voltage signals for advanced diagnostics. With power requirements ranging from +12 to +35 Vdc and support for loop resistance up to 1,000 Ω at 35 Vdc, this transmitter provides a dependable, efficient solution for continuous vibration monitoring across critical rotating machinery.
