Product Description
The Bently Nevada 143729-01 Cylinder Pressure I/O Module enables precise measurement and signal conditioning of cylinder pressures. It integrates seamlessly with Bently-approved third-party pressure transducers. Internal terminations simplify installation and ensure fast integration into monitoring systems.
This module accurately measures cylinder, discharge, and suction pressures. It also calculates maximum and minimum pressures, compression ratio, peak rod compression/tension, and degree of rod reversal. The system provides real-time pressure data for predictive maintenance and operational safety.
