BENTLY 330101-00-08-05-02-00 electric eddy current sensor

Working principle: Based on the eddy current effect, the high-frequency magnetic field generated by the sensor probe induces eddy current on the conductive metal surface near it, and the magnetic field generated by the eddy current reacts on the probe, causing the impedance of the probe coil to change. By measuring the impedance change, the distance between the probe and the metal surface is detected, so as to measure the displacement, vibration and other parameters of the object.

Technical parameters:
Measuring range: Usually 0.1mm to 2mm, small displacement changes can be accurately measured.
Sensitivity: Up to 0.1μm/division, can capture extremely fine vibration or displacement signals.
Output type: 4-20mA current signal, easy to connect with various industrial control system interfaces.
Operating temperature: can work stably at -40 ℃ to + 100℃ ambient temperature, adapt to a variety of harsh industrial environment.
Protection level: Generally IP67, with good dust-proof, waterproof performance, can operate reliably in wet, dusty and other environments.
Installation method: non-contact installation, will not cause interference or damage to the measured object, easy to integrate into a variety of rotating equipment.

Functional features:
High-precision measurement: Advanced electronic circuit and signal processing technology can provide high-precision measurement results to help accurately evaluate equipment operating status.
Strong anti-interference ability: with good electromagnetic compatibility, can effectively inhibit external electromagnetic interference, to ensure stable work in complex industrial electromagnetic environment.
High durability: The use of high-quality stainless steel materials and injection molded housing, with high temperature resistance, impact resistance and other characteristics, can be long-term stable operation in harsh industrial environments.

Application: It is mainly used for vibration monitoring and shaft displacement measurement of rotating machinery in various industrial scenarios, such as steam turbines, generators, compressors, pumps, fans, etc. By monitoring these key parameters in real time, the abnormal running status of the device can be discovered in time, which provides an important basis for preventive maintenance of the device.
