Use and storage temperature: the sensor has a wide use and storage temperature range, can adapt to different working environments.

Principle of operation

BENTLY 330704-000-050-10-02-05 sensor adopts eddy current convergence measurement principle. When the coil on the top of the probe is coupled with a high-frequency current and brought into close proximity with a conductive surface, eddy currents are generated on the surface of the conductive object due to the action of the coil's magnetic lines of force, which reduces the inductance of the coil. This change in coil characteristics is converted to a DC voltage signal output, which enables the measurement of displacement or vibration.

Applications

The sensor is widely used in various industrial fields, especially where vibration and displacement of large rotating machinery (such as steam turbines, hydraulic turbines, fans, compressors, etc.) need to be monitored. It can provide important data support for equipment condition monitoring, fault early warning and maintenance, which helps to reduce equipment failure and improve production efficiency.

Installation and Maintenance

Installation: The sensor should be installed in the machine can accurately reflect the displacement or vibration of the position. In the installation process, should ensure that the sensor's electrical connections are correct and reliable, and avoid exposure to extreme temperatures or humidity.

Maintenance: Sensors should be maintained and calibrated regularly to ensure their measurement accuracy and reliability. During maintenance, care should be taken to check that the leads, connectors and internal structure of the sensor are in good condition and should be replaced or repaired if damaged.
