Product Overview
The Emerson EZ1080-05-00-015 is an 8mm eddy current sensor engineered for critical turbomachinery protection. Designed to measure radial and axial shaft displacement, position, eccentricity, and speed, this sensor ensures reliable performance in steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. Its non-contact design eliminates wear, while robust construction minimizes signal drift even under harsh conditions. With a linear measurement range of 2 mm and an incremental scale factor of either 7.87 V/mm (API) or 8 V/mm (ISO), the Emerson EZ1080-05-00-015 delivers precise data for condition monitoring and control systems.

Industry Applications
The Emerson EZ1080-05-00-015 excels in high-stakes environments where accurate shaft monitoring is vital. In steam turbines, it detects subtle vibrations that could signal bearing wear or misalignment. For gas compressors, the sensor’s stable output over a -35 to 180°C range ensures reliable eccentricity readings even during start-up transients. Hydro turbines benefit from its IP67 sealing and stainless steel case, resisting moisture and debris. The sensor’s compatibility with ferromagnetic steels like 42CrMo4 and AISI 4140 makes it a direct fit for most rotating machinery.
Installation and Setup
Mount the Emerson EZ1080-05-00-015 using the M10x1 case thread, ensuring a clean, burr-free hole for proper sealing. The sensor has a 50 mm sleeve and no armored cable—install the 1.5 m FEP cable in a protective conduit if exposed to abrasion. Maintain the initial air gap of 0.5 mm (20 mils) using a non-magnetic feeler gauge. For best linearity, select a target material from the approved list (e.g., 42CrMo4 or AISI 4140) and ensure the shaft diameter meets the recommended 25 mm minimum. Ground the sensor case to the machine frame to minimize electrical noise.
Troubleshooting Common Issues
Signal instability often stems from improper target material or shaft surface irregularities. Verify the target is from the approved steel list and has a smooth finish. Temperature drift within 0-45°C is compensated, but operation beyond that range may require recalibration. Cable damage—especially near the connector—is a frequent failure point; inspect the FEP jacket regularly. If the sensor fails to meet the deviation from best fit straight line (DSL) of ±0.025 mm, check for contamination on the sensor tip or changes in the initial air gap. The Emerson EZ1080-05-00-015 is SIL 2 capable, but system validation per IEC 61508 is recommended for safety-critical loops.
Selection Guide
When ordering the Emerson EZ1080-05-00-015, confirm the model number includes the correct cable length (015 = 1.5 m) and unthreaded length (00 = 0 mm). If your application requires a 20 mm case length, note that it is only available for the EZ1080 base model. For pressurized environments above 10000 hPa, request the DOC-TEST certificate separately to verify the pressure seal.
