Quick Detail

Description

The 990-05-50-02-01 Vibration Transmitter is a loop-powered device designed for OEM centrifugal compressors, pumps, motors, and fans, providing a reliable 4–20 mA proportional vibration signal. It accepts input from one 3300 NSv Proximity Probe with extension cables up to 5 meters (16.4 ft) and outputs precise peak-to-peak vibration amplitudes, full scale 0–5 mils pp (0–125 μm pp), with a linear range of 0.25–1.65 mm (10–65 mils).

Operating from −35°C to +85°C (−31°F to +185°F) and storing safely between −52°C to +100°C (−62°F to +212°F), the 990-05-50-02-01 Vibration Transmitter handles a maximum loop resistance of 1,000 Ω and 23 mA typical current. Its integrated Proximitor Sensor requires no external unit, while PROX OUT terminals and a coaxial connector provide dynamic vibration and gap voltage signals for diagnostics.

With CSA Division 2 approval, bulkhead mounting, and a potted design for 100% condensing humidity, the 990-05-50-02-01 Vibration Transmitter ensures precise, reliable vibration monitoring in automated machinery applications.

Applications

Vibration Monitoring in Centrifugal Compressors: The 990-05-50-02-01 Vibration Transmitter enables real-time monitoring of centrifugal air compressors in automated control systems. Using the 3300 NSv Proximity Probe, it measures shaft vibration and radial displacement in fluid-film bearings, supporting predictive maintenance and avoiding unplanned downtime.

Condition Monitoring for Pumps, Motors, and Fans: With a system length of up to 5 meters (16.4 ft), the 990-05-50-02-01 Vibration Transmitter is suitable for small pumps, electric motors, and fan systems, delivering precise 4–20 mA signals for integration into PLCs or distributed control systems. The device ensures accurate position and vibration measurements even in constrained installation spaces.

Keyphasor and Speed Reference Applications: The 990-05-50-02-01 Vibration Transmitter can provide dynamic Keyphasor signals for speed monitoring and phase reference, enhancing automation performance in machinery protection and speed control applications.

Specifications
