1、 Product Overview

The EMERSON AMS EZ 1000 eddy current sensor operates based on the principle of eddy current effect, and is capable of non-contact, high linearity, and high-resolution measurement of the distance between the measured metal conductor and the probe surface. This sensor has high environmental adaptability and can work stably in harsh industrial environments, providing important support for vibration monitoring and status management of industrial equipment.

2、 Product Features

Non contact measurement: Eddy current sensors can achieve high-precision distance measurement without direct contact with the measured object, avoiding errors caused by wear and tear in traditional contact sensors.

High linearity and high resolution: Sensors have excellent linearity and resolution, which can accurately capture small displacement changes of the measured object and provide reliable data for equipment status monitoring.

Strong environmental adaptability: The sensor has a high protection level and can effectively resist the erosion of oil, moisture, and chemical substances, making it suitable for various harsh industrial environments.

Strong compatibility: The EMERSON AMS EZ 1000 eddy current sensor supports seamless integration of multiple monitoring systems, such as the MMS 3000/6000 turbine protection system, which provides key phase pulse signals to support phase analysis.

Easy to maintain: The sensor adopts a modular design, and on-site calibration during component replacement can save time and reduce maintenance costs.
