Product Details:

The Emerson 1172C26 is a high-reliability position monitor module designed for large rotating machinery protection systems. This position board receives analog feedback signals from eddy current displacement probes, continuously measuring rotor axial position and shaft offset of rotating equipment. It converts raw sensor signals into standard digital data, compares measured values against preset safety thresholds, and triggers alarm or trip signals once rotor displacement exceeds safe limits to prevent mechanical collision and equipment damage. Built with integrated signal conditioning and noise filtering circuits, it reduces false triggering caused by oil mist, vibration and electromagnetic interference in heavy industrial sites. Industrial-grade electronic components and robust PCB layout are adopted, delivering stable continuous operation in harsh environments of power plants and oil & gas facilities. It adopts rack slot pluggable structure for simple installation and fast replacement inside the monitor cabinet, effectively cutting down equipment maintenance downtime. The Emerson 1172C26 cooperates with vibration monitor modules, speed monitor units and eddy current sensors to provide comprehensive asset protection. It is widely deployed in steam turbines, gas turbines, centrifugal compressors and large rotating pumps, providing reliable rotor position detection and minimizing unexpected shutdown risks of process production equipment.
