Configured for case expansion displacement measurement in Bently Nevada transducer monitoring platforms, the Bently Nevada 135613-01 (24765 Case Expansion Transducer Systems) provides direct physical/electrical execution for converting mechanical thermal expansion movement into proportional DC voltage signals.

Model Identification

The Bently Nevada 135613-01 Case Expansion Transducer System is designed to measure relative expansion movement between machine casings and reference points. The system accepts DC power input and provides a voltage output proportional to measured displacement.

The transducer output range is configured as +1 to +6 VDC, with 135613-01 and 135613-11 models providing a sensitivity of 0.20 V/mm (5.0 V/in). The device is intended for mechanical condition monitoring applications requiring continuous case movement measurement.

Hardware Specifications

Rotor Dynamics and Expansion Measurement

The 135613-01 transducer system provides mechanical displacement feedback for monitoring casing expansion behavior. The measurement circuit converts physical movement into an electrical voltage signal suitable for connection to monitoring equipment.

For accurate rotor dynamics analysis, the transducer installation position and mechanical reference alignment must remain stable. Proper calibration ensures that thermal expansion movement is represented correctly within the monitoring system.

The device operates with a direct voltage output format, eliminating additional signal conversion requirements between the transducer and compatible monitoring inputs.
