Since 2007, our enterprise has been engaged in offering of a broad assortment of Hall Effect Based Vehicle Speed Sensors. Designed with a multiplexer, the offered sensors are used to share vehicle speed information between the modules. The provided sensors are precisely engineered by utilizing optimum quality components at our premises by adept technocrats. In addition, the provided Hall Effect Based Vehicle Speed Sensors are made accessible to the patrons in different specifications.
HALL EFFECT BASED VEHICLE SPEED SENSORS
Modern vehicles use multiplexing to share vehicle speed information between modules. For example, the Variable Assist Power Steering (VAPS) system uses Vehicle Speed Sensor (VSS) input to regulate power steering pressures for higher assist at slow speeds, making parking lot maneuvers easier to perform. The Anti-Lock Brake System (ABS) uses VSS information to determine when a wheel is locked up and releases pressure to that wheel to maintain directional stability. Some vehicles use seperate sensors for the ABS, but it is common that the computer uses the information from the wheel sensors to act as a VSS. For example, many newer Ford vehicles use a rear axle mounted speed sensor for both ABS and computer related vehicle speed functions. Instrument Cluster (IC) and Hybrid Electric Cluster (HEC) modules use vehicle speed info for speedometer operation.
Autograde's VSS is used for contactless speed measurement of even very low speed rotation. Two Hall-effect semiconductor elements in the sensor measure a change in magnetic flux caused by a ferromagnetic gear on the sensor. This magnetic flux change is converted into square wave pulse signals by the built in electronic system.
