Overview

The ANRO VB-Z980008-01-01-10-80 is a high-precision eddy current displacement converter designed to interface with non-contact proximity probes for monitoring critical rotating machinery. It transforms the high-frequency signal from the probe into an analog voltage proportional to shaft displacement, providing real-time data for predictive maintenance and machinery protection.

Its non-contact principle ensures wear-free operation and reliable measurements in harsh environments, including high temperatures, oil, or steam exposure. Typical applications include axial (thrust) vibration, radial shaft displacement, and eccentricity monitoring.

Technical Data

Typical Applications: Machinery Protection Systems

• Steam and Gas Turbines: Monitors thrust bearing position and radial vibration to detect wear, misalignment, or imbalance, helping prevent rubs and catastrophic failures.

• Compressors and Pumps: Provides shaft runout and vibration data for large centrifugal compressors and multi-stage pumps in chemical or petrochemical industries.

• Gearboxes and Motors: Measures radial displacement in high-speed shafts, enabling early detection of misalignment or imbalance.

• Predictive Maintenance Systems: Analog output feeds directly into DCS or turbine supervisory instrumentation (TSI) panels for trending, alarm triggering, and safety trips.

By integrating this converter, plants can maximize machinery uptime and reduce unplanned downtime through early detection of shaft or bearing issues.

FAQ: ANRO VB-Z980008-01-01-10-80

Q1: What does the sensitivity rating of 8.00 V/mm mean?
A1: For every 1 mm change in the gap between the probe tip and the shaft, the converter output changes by 8 V, allowing detection of very small movements with high precision.

Q2: Why is the eddy current system unaffected by oil or steam?
A2: Eddy current sensors respond to changes in electromagnetic fields near the conductive target. Non-conductive materials like oil or steam do not interfere, ensuring accurate measurements even in challenging environments.

Q3: What are the three required components for a complete eddy current displacement system?
A3: 1) Proximity Probe (sensor tip), 2) Extension Cable (transmits the high-frequency signal), 3) Converter (VB-Z980008-01-01-10-80, processes signal and outputs voltage). All must be matched and calibrated for accurate performance.
