The Bently Nevada 990-10-XX-01-00 (MOD 163930-01) is a two-wire, loop-powered vibration transmitter designed to provide a 4-20 mA proportional signal for machinery control systems. This device integrates the Proximitor sensor directly into the transmitter housing, eliminating the need for external signal conditioning units. It is specifically engineered for OEM applications involving small pumps, motors, fans, and centrifugal air compressors.

Features

  • Integrated Proximitor sensor functionality for reduced installation complexity.
  • Non-isolated PROX OUT and COM terminals, supplemented by a coaxial connector.
  • Non-interacting zero and span potentiometers for precise calibration.
  • Dedicated test input pin for rapid verification of loop signal output.
  • Not OK/Signal Defeat circuit to prevent false alarms or erroneous high outputs.
  • Potted construction suitable for high-humidity environments, including up to 100% condensing conditions.

Applications

  • Centrifugal air compressor monitoring.
  • Vibration trending for small pumps and motors.
  • Integration into PLC-based machinery protection systems.
  • General-purpose vibration monitoring in industrial environments.

Installation Guidelines

  • Ensure the system is powered down before performing any wiring, installation, or removal of the module.
  • Mount the transmitter on a 35 mm DIN rail in a location protected from excessive heat and direct moisture.
  • Use shielded cabling for the 4-20 mA loop to minimize electromagnetic interference (EMI).
  • Verify that the proximity probe and extension cable match the system length requirements (5m or 7m) specified for the transmitter.
  • Ensure proper grounding of the signal shield at the control system end to maintain signal integrity.
  • Handle the device with standard ESD precautions to prevent damage to internal circuitry.

FAQ

What is the primary function of the 990-10-XX-01-00?

This transmitter is designed to convert vibration data from a 3300 NSv proximity probe into a 4-20 mA signal, allowing standard PLCs to monitor vibration levels on rotating machinery.

Is this unit compatible with System 1 software?

No, the 4-20 mA output provides peak-to-peak trending data only and does not support the advanced diagnostic capabilities required for systems like Bently Nevada System 1 or Rule Paks.

What system lengths are supported?

The 990-10-XX-01-00 is compatible with 5.0-meter and 7.0-meter system length configurations.
