Bently Nevada 991-25-50-02-05 Description

The 991-25-50-02-05 991 Thrust Transmitter is intended primarily for the 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 axial displacement (thrust) signal as the 

input to their machinery control system. The transmitter is a 2-wire, loop-powered device that 

accepts input from our 3300 NSv* proximity probe and its matching extension cable 

(available in 5 m and 7 m system length options). The transmitter conditions the signal into 

appropriate engineering units proportional to the shaft’s axial position1, and provides it as a 

4 to 20 mA industry-standard signal for input to the control system where machinery protection 

alarming and logic occurs.

The 991-25-50-02-05 991 transmitter provides the following notable features:
-Integrated Proximitor* Sensor requires no external unit
-Non-isolated “PROX OUT " and "COM" terminals plus a coaxial connector provide a dynamic 

vibration and gap voltage signal output for diagnostics3.
-Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.
-Test Input pin allows quick verification of loop signal output, using a variable DC voltage source as the input.
-A Power-up Inhibit circuit eliminates signal errors due to line voltage transients.
-A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe 

or loose connection.
-Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting.
-Potted construction for high humidity (up to 100% condensing) environments.
-Compatibility with 3300 NSv proximity probe allows transducer installation in small areas with minimal 

clearance, typical of centrifugal air compressors.
