Quick Detail

Description

The 991-25-50-02-05 Thrust Transmitter provides a 4 to 20 mA proportional axial displacement signal for machinery control systems. It accepts input from a 3300 NSv Proximity Probe and extension cable up to 5.0 meters. The 991-25-50-02-05 Thrust Transmitter measures linear ranges of 0.25 to 1.65 mm, conditions shaft axial position into engineering units, and outputs through BNC or Prox Out terminals with 10 kΩ impedance. Loop-powered at +12 to +35 Vdc, it limits current to 23 mA and supports bulkhead mounting. Rated for -35°C to +85°C and CSA, ATEX Zone 0/2, and ABS maritime approvals, the 991-25-50-02-05 Thrust Transmitter enables automated axial thrust monitoring, vibration diagnostics, and integration with centrifugal compressors, motors, or pump control systems.

Applications

Measure Axial Thrust in Centrifugal Compressors
Connect the 991-25-50-02-05 Thrust Transmitter to a 3300 NSv Proximity Probe on compressor shafts. The transmitter converts shaft displacement into a 4 to 20 mA signal for automated monitoring and control.

Monitor Rod or Shaft Movement in Motors and Pumps
Install the 991-25-50-02-05 Thrust Transmitter to track small axial movements. Its 0.25 to 1.65 mm linear range ensures precise measurement for integration with DCS or PLC systems.

Provide Keyphasor and Vibration Diagnostic Signals
Use the 991-25-50-02-05 Thrust Transmitter Prox Out and BNC connectors to output dynamic vibration or gap voltage signals for automated diagnostics and predictive maintenance.

Simplify Installation in Confined Spaces
The 991-25-50-02-05 Thrust Transmitter accepts standard 5.0-meter extension cables and bulkhead mounting, enabling rapid installation in tight compressor, fan, or pump housings.

Specifications

Competitive Advantage

Direct 4 to 20 mA Output for Automation Systems
The 991-25-50-02-05 Thrust Transmitter converts axial displacement into an industry-standard 4 to 20 mA signal, ready for PLC, DCS, or control loop input.

Supports Dynamic Vibration and Gap Signal Diagnostics
Non-isolated Prox Out and BNC terminals provide real-time vibration and gap voltage output from the 991-25-50-02-05 Thrust Transmitter, allowing automated condition monitoring.

Quick Loop Verification and Adjustment
Non-interacting zero and span potentiometers and a test input pin enable fast verification and adjustment of the 991-25-50-02-05 Thrust Transmitter signal without system downtime.

Prevent False Alarms and High Outputs
The Not OK/Signal Defeat circuit in the 991-25-50-02-05 Thrust Transmitter avoids high outputs or false alarms caused by loose connections or faulty probes.

Operate Across Harsh Industrial Environments
Rated -35°C to +85°C, with CSA, ATEX Zone 0/2, and ABS approvals, the 991-25-50-02-05 Thrust Transmitter supports automated monitoring in compressors, pumps, motors, and fan systems exposed to temperature extremes or moisture.
