Bently Nevada 991-06-50-01-00 Thrust Transmitter

Description
This 991-06-50-01-00 is transmitter provides a 4-20 mA signal proportional to thrust position, ideal for monitoring shaft axial displacement. It is a 2-wire, loop-powered device designed to accept inputs from the 3300 NSv proximity probe and its matching extension cable. The transmitter conditions these inputs into appropriate engineering units for accurate axial position readings.
