Features:

  • The 990-05-70-03-00 features a two-wire, loop-powered design for simple integration into OEM control systems.
  • This model includes a 0-5 mils pp (0-125 μm pp) full-scale range with a 7.0 meter system length.
  • The 990-05-70-03-00 mounts securely using DIN clips and screws for reliable installation in control panels.
The 990-05-70-03-00 provides essential vibration monitoring functions common to the 990 series, and is a practical solution for measuring general vibration levels and providing overall trending data. It features a 0-5 mils pp (0-125 μm pp) full-scale range with a 7.0 meter (23.0 feet) system length, eliminating the need for separate extension cables in many installations. The 990-05-70-03-00 mounts using DIN clips and screws, ensuring secure installation in control panels without requiring specialized tools.

For applications requiring simplified system architecture, the 990-05-70-03-00 delivers reliable peak-to-peak trending data while maintaining compatibility with 3300 NSv proximity probes. However, this transmitter has limitations compared to continuous monitoring systems. The 4-20 mA signal from the 990-05-70-03-00 cannot determine vibration phase, and advanced functions such as gap alarms, phase alarms, Danger Bypass, and Trip Multiply are not supported.

The 990-05-70-03-00 solves the pain point of integrating vibration monitoring into OEM control systems with a simple, proportional 4-20 mA output. While PLCs attached to this transmitter can only provide peak-to-peak trending data and are not suitable for plant-wide diagnostic systems like System 1 or Rule Paks, the 990-05-70-03-00 provides a cost-effective solution for centrifugal air compressors, pumps, motors, and fans where basic trending is sufficient without full diagnostic capability.

The 990-05-70-03-00 Bently Nevada 990 Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer GE / Bently Nevada
  • Model 990-05-70-03-00
  • Condition New Original ready stock
  • Product Family 990-08-70-03-00,990-10-70-03-00,990-05-50-03-00
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • OEM Mechanical Integration: Widely used by manufacturers of centrifugal air compressors, small cooling tower fans, motors, and industrial pumps.
  • Confined Space Monitoring: Ideal for installation in extremely confined spaces within bearing housings where conventional probes cannot access, thanks to the 3300 NSv (Narrow Side View) probe.
  • Non-Critical Asset Protection: Suitable for auxiliary equipment in factories where the expensive 3500 monitoring unit is not required, but continuous monitoring of vibration trends is still necessary.
  • 4-20 mA Current Circuit: This is a two-wire device that receives power and transmits proportional vibration signals through the same pair of wires, directly connecting to an analog input card of a PLC (Programmable Logic Controller) or DCS (Distributed Control System).
  • Dynamic Signal Output (Prox Out): The transmitter panel provides a non-isolated dynamic signal connector (typically BNC or terminal). Technicians can obtain the raw vibration waveform and gap voltage at this contact for fault diagnosis and spectrum analysis.
  • Power Requirements: Accepts a wide voltage input range of +12 to +35 Vdc.
  • Signal Shielding Protection (Not OK Circuit): Features self-diagnostic capabilities. When a probe is damaged or the cable is disconnected, the output current drops to < 3.6 mA. The control system can identify this state as a "sensor failure" rather than "high vibration," thus preventing false trips.
  • Environmental Compliance: Internal circuitry is fully potted, compliant with IEC 68-2-3 humidity and heat testing, and possesses excellent resistance to chemical corrosion and high humidity.
  • Electromagnetic Compatibility (EMC): Designed to comply with European CE standards, it has strong immunity to radio frequency interference (RFI), ensuring signal stability even in environments with strong electromagnetic interference.
Description
The 990-05-70-03-00 operates as a two-wire, loop-powered vibration transmitter designed for OEM applications such as centrifugal air compressors, pumps, motors, and fans. It continuously accepts input from 3300 NSv proximity probes and matching extension cables, conditioning the signal into appropriate peak-to-peak vibration amplitude engineering units. 

The 990-05-70-03-00 features a 0-5 mils pp (0-125 μm pp) full-scale range with a 7.0 meter (23.0 feet) system length, eliminating the need for separate extension cables in many installations. It mounts on DIN clips and screws for secure installation in control panels.

The 990-05-70-03-00 provides essential vibration monitoring functions for OEM equipment manufacturers who prefer a simple 4-20 mA proportional signal. This transmitter is a practical solution for measuring general vibration levels and providing overall trending data.

The 990-05-70-03-00 solves the pain point of integrating vibration monitoring into OEM control systems with a simple, proportional 4-20 mA output. While the 4-20 mA signal cannot determine vibration phase or support advanced functions like gap alarms or Trip Multiply.
