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

Description

The 991-06-50-01-00 is a thrust position transmitter designed for continuous shaft axial displacement monitoring in rotating machinery systems. It converts proximity probe signals into a proportional industrial output for integration with turbine supervisory instrumentation, machinery protection systems, and distributed control systems.

The transmitter supports thrust measurement applications in steam turbines, compressors, pumps, and other critical rotating assets where axial shaft movement monitoring is required. The unit is compatible with proximity probe systems using a 5.0 metre system length configuration and supports DIN-rail installation for industrial control panels.

Designed for machinery condition monitoring environments, the 991 Thrust Transmitter provides reliable signal conditioning and simplified integration into plant monitoring architectures.
