Bently Nevada 990-05-XX Vibration Transmitter

Description：

The 990-05-XX vibration transmitter is designed for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans. It delivers a 4-20 mA proportional vibration signal for integration into machinery control systems.

Features:

• Integrated Proximitor Sensor: Removes the need for a separate sensor unit.
• 4-20 mA Output: Provides an industry-standard signal for seamless integration with control systems.
• Non-Isolated Outputs: Offers diagnostic capabilities for advanced monitoring.
• Zero and Span Potentiometers: Allow for easy field calibration.
• Test Input Pin: Facilitates quick verification of loop signal output using a function generator.
• Power-Up Inhibit Circuit: Prevents signal errors from line voltage transients.
• Not OK/Signal Defeat Circuit: Avoids high outputs or false alarms due to a faulty proximity probe or loose connection.
• Mounting Options: Provides choices of DIN-rail clips or bulkhead mounting screws.
• Potted Construction: Suitable for environments with high humidity (up to 100% condensing).
• Compatibility: Works with the 3300 NSv proximity probe, enabling installation in confined spaces with minimal clearance.

Specifications:

• Measurement Range: Full-scale range of 0.6 mm (0.024 inches).
• Output Signal: 4-20 mA.
• Power Supply: 12 to 36 VDC.
• Operating Temperature: -40 to 85°C.
• Humidity: 0 to 100% RH (non-condensing).
