4. Product Structure and Operating Principle

The 990-04-50-01-05 proximity transmitter operates together with a compatible proximity probe system. The probe generates measurement signals based on the distance change between the probe tip and the rotating shaft surface.

When the shaft moves due to vibration, imbalance, misalignment, or mechanical stress, the transmitter receives the signal from the probe and processes it internally. After signal conditioning and conversion, the transmitter provides a stable output signal for machinery monitoring equipment.

This operating principle allows operators to continuously observe shaft conditions and identify abnormal operating trends before equipment damage occurs.
