The 990 Vibration Transmitter is designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans. It provides a simple 4 to 20 mA proportional vibration signal as input to machinery control systems. The transmitter is a 2-wire, loop-powered device that accepts input from the 3300 NSv* proximity probe and its matching extension cable, available in 5 m and 7 m system length options. It conditions the input signal into appropriate peak-to-peak vibration amplitude engineering units and outputs this value as a proportional 4 to 20 mA industry-standard signal, which is then used by the control system for machinery protection and alarming.FAQ
1. What type of signal does the 990 Vibration Transmitter provide?
The transmitter provides a 4 to 20 mA industry-standard signal, which represents the vibration level of the machinery.
2. Can the 990 Vibration Transmitter be used with any type of proximity probe?
No, it is specifically designed to work with the 3300 NSv proximity probe and its matching extension cables.
3. What applications is the 990 Vibration Transmitter best suited for?
It is best suited for use in monitoring vibration levels in machinery like centrifugal air compressors, small pumps, motors, and fans, helping with machinery protection and maintenance.
