Bently Nevada 991-01-XX-01-05 Thrust Transmitter

Description：

The 991 Thrust Transmitter offers a straightforward 4-20 mA proportional axial displacement (thrust) signal for integration into machinery control systems. This 2-wire, loop-powered device works with the 3300 NSv proximity probe and its corresponding extension cable.

Features：

• Integrated Proximitor Sensor: Eliminates the need for an external unit.
• Non-Isolated Outputs: Provides dynamic vibration and gap voltage signals for diagnostic purposes.
• Zero and Span Potentiometers: Facilitates loop adjustment.
• Test Input Pin: Enables quick verification of the loop signal output.
• Power-up Inhibit Circuit: Prevents signal errors from line voltage transients.
• Not OK/Signal Defeat Circuit: Avoids high outputs or false alarms due to faulty proximity probes or loose connections.
• Mounting Options: Offers DIN-rail clips or bulkhead mounting screws.
• Potted Construction: Suitable for high humidity environments.
• Compatibility: Designed to work with 3300 NSv proximity probes for compact installations.
