The 990 Vibration Transmitter is intended primarily for theoriginal equipment manufacturers (OEMs) of centrifugal aircompressors or small pumps, motors, or fans who prefer toprovide a simple 4 to 20 mA proportional vibration signal asthe input to their machinery control system.The transmitter is a two-wire, loop-powered device thataccepts input from our 3300 NSv proximity probe and itsmatching extension cable (available in 5 m and 7 m systemlength options).
The 990-05-70-03-05 Bently Nevada Vibration Transmitter may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

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.
The transmitter is a 2-wire, loop-powered device that accepts input from a Bently Nevada 3300 NSv proximity probe and its matching extension cable. The 3300 NSv probe is specifically selected for this application because its reduced tip diameter and compact body allow installation in tight clearances typical of centrifugal air compressors and small-frame rotating equipment. The transmitter conditions the eddy-current signal into appropriate peak-to-peak vibration amplitude engineering units and provides this value as a proportional 4-20 mA industry-standard signal to the control system where machinery protection alarming and logic occur.
- Steam Turbines:Radial vibration, thermal growth & rotor stability at bearings
- Gas Turbines:High-speed dynamics & eccentricity during startup/operation
- Industrial Turboexpanders:Stability in high-velocity gas expansion
- Centrifugal Compressors:High-frequency rotor vibration & aerodynamic loading anomalies
- Axial Compressors:Radial displacement for large multi-stage rotors
- Boiler Feed Pumps:Avoid bearing failure in critical power plant pumps
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Thread Engagement: Limit thread engagement depth to 1.5 times the nominal thread diameter to prevent component binding during installation.Target Mechanical Gap: Thread the probe into the bracket while monitoring its output voltage or using a physical feeler gauge. Secure the probe locknut once the gap is fixed between 0.5 mm and 1.75 mm (20 to 55 mils). This places the sensor in its linear operating region
FAQs
-
What is 990-05-70-03-05?
+The Bently Nevada 990-05-70-03-01 is a two-wire, loop-powered vibration transmitter -
What type of probe is compatible with the 990-05-70-03-01?
+This transmitter is designed specifically to work with the 3300 NSv proximity probe and its matching extension cables. -
Can the 7.0-meter option be mixed with 5.0-meter components?
+No. The total electrical length of the probe plus the extension cable must match the 7.0-meter system length configuration to maintain signal calibration and prevent measurement errors. -
What are the power requirements?
+It requires an external loop supply voltage between +12 to +35 Vdc at the transmitter terminals.
