Applications
The Emerson EZ1081-RM-00-010 410 is designed for steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. Its non-contact measurement of radial and axial shaft dynamic displacement, position, eccentricity, and speed helps prevent catastrophic failures. In a compressor application, the sensor's high-temperature capability and IP68 sealing ensure accurate readings even in oil-mist environments, lowering total cost of ownership.
Installation & Setup
Mount the Emerson EZ1081-RM-00-010 with its M10x1 thread and 0 mm unthreaded length. The reverse mount configuration simplifies access in confined spaces. Ensure the target material matches one of the listed ferromagnetic steels. The 1 m armored cable requires careful routing to avoid damage. Set initial air gap to 0.5 mm (20 mils) for optimal linear range. Refer to the converter documentation for area classification when used in hazardous locations.
Maintenance & Reliability
The IP67 enclosure protects against dust and water ingress; for submerged applications, order DOC-TEST certificate for IP68 compliance. The sensor's glass-fiber reinforced PEEK tip and stainless steel case resist harsh chemicals and temperatures. Periodic inspection of cable and connector integrity is recommended. The SIL 2 capability (SC 2 per IEC 61508) enhances system safety, reducing costly failures and extending sensor life.
Selection Guide
Verify compatible converter documentation for area classification. The Emerson EZ1081-RM-00-010 comes with intrinsic safety and increased safety approvals (ATEX, IEC-Ex, CSA, etc.). For additional pressure sealing test, order DOC-TEST separately. UBEST Automation (ubest101) offers this sensor with full traceability and support, ensuring you receive genuine Emerson parts for your critical machinery.
