Functional Details:
Provides a 4-20 mA signal proportional to relative vibration.
Accepts input from the 3300 NSv non-contacting proximity probe and its extension cable.
Key features include an integrated Proximitor Sensor, non-isolated “PROX OUT” and “COM” terminals, and a test input pin for signal verification.
Suitable for machinery protection and alarming.
Potted for high humidity environments (up to 100% condensing)
Compatible With NSv Probes: The 990 and 991 work with our 3300 narrow side view (NSv) proximity probes.
The 990 and the 991 both employ an integrated proximity probe, thus negating the need for an external unit.
The 990 and the 991 both feature a Not OK/Signal Defeat circuit to prevent high outputs due to a faulty proximity probe or loose connection.
The 990 and the 991 both feature potted construction for high humidity environments (up to 100% condensing)
Installs in Tight Spots: Enables transducer installation in small spaces with minimal clearance.

The 990 (Vibration) and 991 (Thrust) Transmitters are intended for original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional vibration or axial displacement (thrust) signal as the input to their machinery control system. Both transmitters are compatible with our 3300 NSv and the narrow sideview proximity probes allow for transducer installation in small spaces with minimal clearance.
Our 177230 Seismic Transmitter is a self-contained piezo-accelerometer that offers condition monitoring of general-purpose machinery with rolling element bearings. The 177230 produces 4 to 20 mA primary signal outputs to a control system and a secondary dynamic signal for diagnostics. It is suitable for motors, pumps and small reciprocating compressors where accelerometer monitoring is appropriate. Bently Nevada offers CSA/NRTL/C, ATEX/IECEx certifications for Hazardous Areas with potentially flammable atmospheres. The product has a sensitivity of 10.2 mV/m/s^2 (100 mV/g) ± 20% and a frequency response of 10 Hz to 1 kHz (600 cpm to 60 kcpm) ± 10% and 1Hz to 10 kHz (60cpm to 600 kcpm) ± 3 dB.
