It is engineered to perform precise, continuous measurement of shaft axial displacement, commonly referred to as thrust position. By monitoring the proximity of the shaft to the thrust bearing, this module provides critical data for rotating equipment such as large steam turbines, gas compressors, and centrifugal pumps, enabling early identification of mechanical wear or potential catastrophic failure.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDirect interface with proximity probe transducer systems (Proximitor sensors) for high-accuracy displacement measurement.\u003c\/li\u003e\n\u003cli\u003eContinuous signal processing with real-time comparison against user-defined Alert and Danger setpoints.\u003c\/li\u003e\n\u003cli\u003eIntegrated proportional 4–20 mA output for external trending and data integration.\u003c\/li\u003e\n\u003cli\u003eOn-board LED status indicators providing instant visual confirmation of OK, Bypass, Alert, and Danger states.\u003c\/li\u003e\n\u003cli\u003eRobust relay output configuration for automated machinery shutdown or alarm annunciation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis module is specifically utilized in critical rotating machinery protection schemes.
