Functional Description
The 990-05-70-02-01 transmitter accepts input from a Bently Nevada 3300 NSv proximity probe and extension cable (available in 5 m and 7 m lengths). As a two-wire, loop-powered device, it draws operating power from the same wires used to transmit its output signal.
Its core function is to condition probe signals into engineering units representing peak-to-peak vibration amplitude, then output this as a 4–20 mA current. This industry-standard signal integrates easily into control systems, enabling alarms, shutdowns, or other protective logic based on vibration levels. A key feature is the integrated Proximitor sensor, simplifying installation and reducing system complexity.
