Magnetic Hall Effect Sensors: BH Series

Brand: AI-Tek Instruments LLC

The BH Series are Bi-directional, zero velocity sensors are self-calibrating to the specific customer application and provide two independent frequency outputs and a direction signal output to indicate change in direction of the sensed, ferrous target.

The BH Series bi-directional sensor can also be referred to as a dual-channel sensor since it utilizes two Hall effect sensing elements that 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.
