Specification of Bently Nevada 990 Vibration Transmitter Murah
Integrated Proximitor Sensor requires no external unit
Non-isolated “PROX OUT" and "COM" terminals plus a coaxial connector to provide a dynamic vibration and gap voltage signal output for diagnostics
Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment
Test Input pin for quick verification of loop signal output, using a function generator 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
