DWQZ series proximitor Axial displacement Eddy current sensor

Short Description:

Eddy current sensor is a non-contact linear measurement tool. It has the advantages of good long-term reliability, wide measurement range, high sensitivity, high resolution, fast response, strong anti-interference, free from the influence of oil and other media, so it is widely used in power, petroleum, chemical, metallurgical and other industries, such as steam turbine, water turbine, blower, compressor, gearbox, etc Dynamic and static non-contact displacement measurement of large rotating machinery such as large cooling pump.

DWQZ series Eddy current sensor is composed of three parts: DWQZ probe, DWQZ extension cable and DWQZ proximitor.

Product Detail

Eddy current sensor DWQZ series

The Eddy current sensor is the core part of the system. It includes the circuits of oscillation, linear detection, filtering, linear compensation and amplification of the whole sensor system. Together with the extension cable and probe, it forms DWQZ axial displacement turbine sensors of various specifications. According to the diameter specification of the probe, DWQZ Eddy current sensor is divided into three parts:φ 8mm、φ11mm、φ25 mm .There are three specifications. According to the total length of system cable (probe cable length + extension cable length), each specification can be divided into 5M and 9M.
