Designed for industrial reliability, the 330704-005-040-10-01-00 offers outstanding measurement accuracy and long service life.
Key features include:
Its compact dimensions make it especially suitable for installations with limited mounting space while maintaining excellent sensing performance.
The 330704-005-040-10-01-00 operates using proven eddy current sensing technology.
A high-frequency electromagnetic field is generated at the probe tip. When positioned close to a conductive rotating shaft, eddy currents are induced on the shaft surface. Variations in the distance between the probe and the shaft change the strength of the electromagnetic field, producing proportional electrical signals.
These signals are processed by a compatible Proximitor Sensor, providing precise measurements for:
