TQ 402 & TQ 412 / EA 402 / IQS 452 Proximity Transducer System responsible for accurately capturing the relative shaft vibration and axial position of critical rotating machinery (such as steam turbines, gas turbines, compressors, and pumps), providing the most fundamental and core data for equipment protection and predictive maintenance. This guide aims to provide engineers and technicians with a complete technical reference covering the entire lifecycle from system selection and configuration to long-term operation and maintenance.

The TQ402/TQ412, EA402 and IQS900 form a proximity measurement system, from VM product line. This proximity measurement system allows contactless measurement of the relative displacement of moving machine elements.TQ4xx-based proximity measurement systems are particularly suitable for measuring the
