Applications & Use Cases
The Emerson EZ1080-18-08-010 excels in turbomachinery monitoring. For example, in steam turbines, it measures radial shaft vibration and axial position, enabling early detection of misalignment or bearing wear. In compressors, the sensor provides eccentricity and speed data critical for surge control. Its SIL 2 capability ensures safe operation in safety-instrumented functions. The non-contact design eliminates wear and reduces maintenance intervals, contributing to lower total cost of ownership.
Installation & Setup Guidance
Mount the Emerson EZ1080-18-08-010 with the M10x1 threaded case into a compatible probe holder. Ensure the target material is ferromagnetic steel as listed (e.g., 42CrMo4, C35, 4140). Set the initial air gap to 0.5 mm (20 mils) for optimal linear range. The 1 m cable with FEP insulation handles high temperatures up to 180°C at the sensor end. Avoid bending the cable below -35°C. For pressure-sealed applications, order the DOC-TEST certificate separately.
Maintenance & Reliability
The sensor’s stainless steel case and PEEK tip resist harsh environments. IP67 protection guards against dust and water ingress. No routine calibration is needed if the target material matches specifications. Periodic visual inspection of the cable and connector is recommended. The extended temperature range (-35 to +180°C) ensures reliability in extreme conditions, reducing unplanned downtime.
Selection Guide & Purchasing Advice
Before purchasing the Emerson EZ1080-18-08-010, verify the cable length (1 m), case length (180 mm), unthreaded length (80 mm), and thread size (M10x1). Confirm the target material and shaft diameter meet the recommendations (minimum 20 mm shaft). For customized requirements, contact PLC Source PRO.
