Product Description
The 990 Vibration Transmitter is engineered for original equipment manufacturers (OEMs) of centrifugal air compressors, as well as small pumps, motors, and fans. It delivers a simple 4 to 20 mA proportional vibration signal for direct input into machinery control systems, enabling seamless integration with existing control and monitoring infrastructure.
This two-wire, loop-powered device accepts input from the 3300 NSv proximity probe along with matching extension cables, available in 5 m and 7 m system lengths. The combination ensures precise and reliable vibration measurement while offering flexible installation configurations.
The 990 conditions incoming signals into peak-to-peak vibration amplitude engineering units and outputs this as a proportional 4 to 20 mA industry-standard signal. This output is utilized by control systems for comprehensive machinery protection, including alarm generation and logic processing, ensuring safe and efficient equipment operation.
Integrated Sensor & Signal Output
Built-in Proximitor Sensor eliminates the need for external units. Non-isolated PROX OUT and COM terminals, along with a coaxial connector, provide dynamic vibration and gap voltage signals for advanced diagnostic monitoring.
Precision Adjustment & Verification
Non-interacting zero and span potentiometers located under the transmitter label enable precise loop calibration without cross-interference. Test Input pin facilitates rapid verification of loop signal output using a function generator, streamlining commissioning and maintenance procedures.
Reliability & Safety
Not OK / Signal Defeat circuit prevents high outputs or false alarms caused by faulty proximity probes or loose connections, ensuring dependable machinery protection. Potted construction withstands high humidity environments (up to 100% condensing), maintaining operational integrity.
Flexible Installation & Compatibility
Choice of DIN-rail clips or bulkhead mounting screws supports versatile installation options. Fully compatible with the 3300 NSv proximity probe, enabling installation in compact spaces typical of centrifugal air compressors while maintaining signal isolation and loop integrity.
