Product Description
The Bently Nevada 991-06-70-01-05 Thrust Transmitter is a 2-wire, loop-powered device designed to provide an industry-standard 4–20 mA output proportional to axial shaft displacement. It is optimized for use in centrifugal compressors, small pumps, motors, and fans. The transmitter works with the 3300 NSv proximity probe and integrates signal conditioning within a compact, rugged enclosure.
Applications
-
Centrifugal air compressors
-
Small motors and pumps
-
Axial thrust measurement in compact machinery
-
OEM solutions for machinery protection
-
Machinery requiring local monitoring with limited space
Key Advantages
-
Compact & Integrated: Built-in Proximitor Sensor eliminates the need for external modules.
-
Reliable Output: Provides 4–20 mA signal for PLCs and control systems.
-
Diagnostics Ready: Offers PROX OUT signal via coaxial connector for vibration diagnostics.
-
Flexible Mounting: Supports DIN rail or bulkhead installation.
-
Signal Stability: Includes power-up inhibit and Not OK/Signal Defeat features.
-
