GVS-02-002 Hall-Effect Two Channels Speed Sensor
Description
GVS-02-002 is developed on the basis of GVS-02-001 dual channel Hall speed sensor. It has the characteristics of small volume, excellent performance and high measurement accuracy. It is used to detect the speed, linear speed and acceleration of wheel axle, rack, concave convex keyway, etc. The phase signal processing circuit is added to the sensor. There is a group of output signals to identify the positive and negative rotation. When the rotation direction is consistent with the arrow direction of the probe, the first channel is ahead of time, and the second channel is lagging behind. The turn signal output is high level, and the direction indicator light is off; otherwise, it is low level, and the direction indicator light is on; it has no contact with the gear to be tested, no wear and tear, and convenient installation. It has the function of polarity and short circuit protection, wide speed measurement range, zero speed and high speed detection, wide temperature range and strong seismic resistance.
