Functiona l Descript ion :
The W SH315 is a new version of WSH135 with better measuring range
and thermal shift. It integrates Hall sensing element, linear amplifer, sensitivity
controll er and emitter foll ow er output stag e. I t accurat ely trac ks extremely small
change in mag net ic flu x density –generally too small to operate Hall effect
switch.
W 315 can be applied as current sensor, tooth sensor, proximity detectors
and motion det ec tor s. As sensit ive monitor of magnetic flux, it ca n effectively
measure a system’s performance with negligible system loading while
providing isolation from contaminated and electrically noisy environments.
