990-05-70-01-00 Bently Nevada 2-Wire Vibration Transmitter

Description:

The Bently Nevada 990-05-70-01-00 is a vibration transmitter designed for original equipmentmanufacturers (0EMs) of centrifugal air compressors, small pumps, motors,or fans. It generates a 4to 20 mA proportional vibration signal for machinery control systems. This two-wire, loop-powereddevice interfaces with the 3300 NSv proximity probe and its matching extension cable (offered in 5Mand 7 m system length options). The transmitter processes the signal into peak-to-peak vibrationamplitude engineering units, delivering it as a proportional 4 to 20 mA industry-standard sianal tothe control system for machinery protection and logic.

-Integrated Proximitor Sensor eliminates the need for an external unit

-"PROX 0UT" and "COM" terminals, along with a coaxial connector, provide dynamic vibration and gapvoltage signal output for diagnostics

-Non-interacting zero and span potentiometers facilitate loop adjustment

-Test Input pin enables quick verification of loop signal output.

-Not OKSianal Defeat circuit prevents false alarms caused by faulty proximity probes or looseconnections

-Mounting options include DIN-rail clips or bulkhead screws for simplified installation

-Potted construction ensures durability in high-humidity environments (up to 100% condensing)

-Compatible with the 3300 NSv proximity probe, allowing installation in tight clearance areastypical of centrifugal air compressors.
