Description
The Bently Nevada 990-04-50-02-CN Vibration Transmitter is designed for OEMs of centrifugal air compressors, small pumps, motors, or fans who require a simple and reliable 4–20 mA proportional vibration signal for integration into machinery control systems. It converts vibration detected by a 3300 NSv proximity probe into an industry-standard electrical signal, providing accurate peak-to-peak measurement in the range of 0–4 mils (0–100 μm pp).

This transmitter features a two-wire, loop-powered design, making installation simple and efficient. It supports system lengths of 5 m (16.4 ft) and includes non-interacting zero and span potentiometers under the transmitter label, allowing precise loop adjustments without affecting other calibration settings. A Test Input pin enables quick verification of loop signal output using a function generator, providing convenient field diagnostics.

The Bently Nevada 990-04-50-02-CN is equipped with a prox output calibrated for a 10 MΩ load, with an output impedance of 10 kΩ, ensuring compatibility with a wide range of industrial monitoring systems. Bulkhead screw mounting provides secure and stable installation in machinery cabinets or panels.

Designed to operate reliably in challenging environments, this transmitter has an operating temperature range of -35°C to +85°C (-31°F to +185°F) and can be stored at temperatures from -52°C to +100°C (-62°F to +212°F). Its robust design ensures accurate vibration monitoring and simple integration into existing machinery protection systems.
