990-05-70-02-01 Bently Nevada Loop-Powered Shaft Vibration Transmitter for DCS/PLC Control System Integration
Product Overview
This transmitter converts shaft vibration into a 4-20mA DCS/PLC signal for CSA Division 2 hazardous areas. It eliminates the need for monitoring racks, providing a compact and direct vibration tracking solution for rotating machinery.
0-5 mils pp Range
Measures micro-level displacement to flag machinery faults early.
7.0-Meter System
Matches 3300 NSv proximity probes for precise field routing.
4-20mA Output
Connects directly to existing control systems, saving hardware costs.
CSA Div 2 Certified
Approved for hazardous environments without requiring bulky housings.
Engineer's Note
Ensure field loops maintain a steady 12-35 VDC supply to prevent signal clipping during peak transient vibration events.
Application Case
Widely deployed across petrochemical and power generation plants globally to interface proximity sensors directly with plant DCS networks.

Frequently Asked Questions
What is the configuration of 990-05-70-02-01?
The 990-05-70-02-01 belongs to the Bently Nevada 990 series. Its setup covers 0-5 mils pp shaft vibration, a 7m system length, and 3300 NSv proximity probe connection.
Can 990-05-70-02-01 be wired into an existing PLC or DCS?
Yes, many plants use it this way. The output is a standard 4-20mA signal from a 2-wire loop, which can go directly to a PLC vibration input or DCS machinery protection system.
What probe length should be matched with 990-05-70-02-01?
For this part number, the probe and extension cable together need to make up a 7-meter system. A 3300 NSv extension cable 7-meter setup keeps the transmitter within its original calibration range.
Why do users need the PROX OUT terminal on 990-05-70-02-01?
Mostly for troubleshooting. During maintenance, engineers can take dynamic waveform data from PROX OUT while leaving the normal 4-20mA monitoring loop active.
What should be considered for power wiring of 990-05-70-02-01?
Keep the loop supply within 12-35 VDC. A stable power source is important for a loop-powered 2-wire machinery protection setup.
Where can this 990 transmitter be used?
Typical applications include compressors, pumps, industrial fans, and rotating equipment in petrochemical or power plants. The CSA Division 2 approval also supports use in more demanding locations.
