Product Dimensions:
The 990 Vibration 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 vibration signal as
the input to their machinery control system. The transmitter is a 2-wire, looppowered 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 peak-to-peak vibration
amplitude engineering units, and provides this value as a proportional 4 to 20
mA industry-standard signal as the input to the control system where machinery
protection alarming and logic occurs1.
The 990 transmitter provides the following notable features:
• 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 diagnostics2.
• 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.
