Description
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 transmitter conditions the signal into appropriate peakto-peak vibration amplitude engineering units, and providesthis value as a proportional 4 to 20 mA industry-standardsignal as the input to the control system where machineryprotection alarming and logic occurs.

The 990 features an integrated Proximitor Sensor that requires no external unit, reducing installation complexity and saving panel space. The 990 provides non-isolated "PROX OUT" and "COM" terminals plus a coaxial connector to deliver a dynamic vibration and gap voltage signal output for diagnostics. The 990 includes non-interacting zero and span potentiometers under the transmitter label that support loop adjustment, allowing for easy field calibration without special tools. The 990 also features a Test Input pin for quick verification of loop signal output using a function generator as the input, streamlining commissioning and maintenance procedures.

Side Clearance: Maintain the minimum specified body clearance from surrounding metals to avoid false eddy current detection.
Thread Engagement: Ensure internal thread engagement does not exceed 1.5 times the nominal thread diameter to prevent binding.
Gapping: Use a digital multimeter on the transmitter’s "PROX OUT" and "COM" terminals to read the DC gap voltage. Adjust the probe placement until the voltage matches the center of the probe's linear range
Technical notes
The model configuration 990-05-70-01-06 provides a full-scale measurement range of 0–5 mils peak-to-peak (0–125 μm peak-to-peak) and is configured for a 7-meter transducer system length. The transmitter mounts directly on a standard 35 mm DIN rail, simplifying installation inside control panels and equipment enclosures.
FAQs
-
What probes are compatible with this model?
+It is designed exclusively to work with the Bently Nevada 3300 NSv proximity probe and its matching extension cable. This combination is ideal for confined spaces and small-clearance machinery. -
What is the 990-05-70-01-06?
+The Bently Nevada 990-05-70-01-06 is a two-wire, loop-powered vibration transmitter designed primarily for Original Equipment Manufacturers (OEMs) to deliver a 4 to 20 mA proportional vibration signal directly to a machinery control system -
What is the function of the 990-05-70-01-06 transmitter?
+It integrates a Proximitor sensor and a signal conditioner into a single device. It processes the raw eddy-current signal from a proximity probe and outputs an industry-standard 4-20 mA linear loop signal representing peak-to-peak shaft vibration. This signal routes to a PLC or DCS for machinery protection and alarming -
Which proximity probes are compatible with this unit?
+This model is designed exclusively to work with the Bently Nevada 3300 NSv proximity probe and its matching extension cable. It is ideal for confined spaces with minimal clearance, such as centrifugal air compressors, small pumps, motors, and fans.
