The Thrust Position Transmitter Bently Nevada 991-06-XX-01-05 MOD:164113-01 is a 2-wire loop-powered device converting axial displacement to 4-20 mA signals, featuring integrated Proximitor, diagnostic output, and CSA/ATEX approvals for compressor monitoring.

High-Resolution Measurement

• Axial Displacement Range: 0.6-0-0.6 mm measurement range for precise thrust position monitoring.

• 4-20 mA Output: Industry-standard proportional signal for seamless integration with control systems.

• Diagnostic Capability: Non-isolated PROX OUT and coaxial connector provide dynamic vibration and gap voltage signals.

• Loop Adjustment: Non-interacting zero and span potentiometers under the label for accurate calibration.

• Test Input Pin: Enables quick verification of loop signal output using variable DC voltage source.

• Signal Integrity: Power-up inhibit and Not OK/Signal Defeat circuits prevent errors from transients or faulty probes.
