AI-Tek BH1512-014 bi-directional, zero velocity sensor provides two independent frequency outputs and a direction signal output to indicate change in direction of sensed, ferrous target. AI-Tek bi-directional sensors are self-calibrating to the specific customer application.

The bi-directional sensor can also be referred to as a dual channel sensor since it utilizes two hall effect sensing elements, physically offset from each other. Each element generates a single channel of target information, identical in frequency and polarity, but offset in the time domain (phase shifted).

Special circuits inside the sensor are designed to calibrate each channel to its application target, then analyze these two channels of information for a phase lead/ lag condition. The direction output will then provide a logic 1 level for clockwise or a logic 0 for counterclockwise rotation, assuming proper sensor orientation.
