Description

The Bently Nevada 990-04-70-01-00 is a dedicated vibration transmitter designed for continuous monitoring of radial vibration in industrial machinery. As part of the 990 series, this unit provides a reliable, cost-effective solution for applications where a full-scale rack-based monitoring system is not required. It converts raw vibration signals into a proportional 4-20 mA output, allowing for direct integration into PLCs, DCS, or SCADA systems for machinery protection and condition monitoring.

Features

  • Full-scale range: 0-4 mils pp (0-100 um pp)
  • Cable length: 7.0 meters (23.0 feet)
  • Mounting: Integrated 35 mm DIN rail clips for standard industrial cabinet installation
  • Adjustments: Non-interacting external zero and span controls for precise calibration
  • Power requirements: Operates on +12 to +35 Vdc input at the transmitter terminal
  • Current limiting: 23 mA typical protection

Installation Guidelines

  • Ensure the transmitter is mounted in a clean, dry environment within the specified temperature range.
  • Use the provided 35 mm DIN rail clips for secure attachment to the equipment rack or panel.
  • Ensure all wiring is shielded and routed away from high-voltage power lines to prevent EMI/RFI interference.
  • Verify correct polarity of the +12 to +35 Vdc power supply before applying power to the terminal.
  • Perform calibration using the external zero and span adjustments only after the system has reached thermal equilibrium.
  • Always disconnect power before installing or removing the module from the DIN rail.

FAQ

What is the primary function of the 990 vibration transmitter?

The 990 transmitter is designed to monitor radial vibration on rotating machinery and provide a 4-20 mA output signal proportional to the vibration level, which is ideal for simple monitoring applications.

Can the zero and span be adjusted on this unit?

Yes, the 990-04-70-01-00 features non-interacting external adjustments that allow for precise calibration of the zero and span settings without affecting the other parameter.

What type of mounting does this model support?

This specific model is configured with 35 mm DIN rail clips for standard industrial mounting.
