Speed sensor

SPH318-2FS Hall gear tachometric transducer

It is often used in electronic control engine to judge the current rotating speed and position of the crankshaft. Through the rotation of the signal disk, the cutting of the magnetic force line and the induction of core are achieved, and the signal Output. Through the modulation in the electronic control unit, high precision square wave signal is obtained.

  • Model: SPH318-2FS

Introduction:

SPH318-2FS Hall gear tachometric transducer has a simple structure, small size  characteristics  and can measure the gear or rotating object's speed by non-contact, so it is easy to operate, service reliable and free to maintenance.  It has strong anti-interference  capability and wide temperature tolerance range,  and is not affected by air pollution, oil pollution and  other media on the test site. It is often used in  electronic control engine to judge the current rotating  speed and position of the crankshaft. Through the  rotation of the signal disk, the cutting of the magnetic  force line and the induction of core are achieved, and  the signal Output. Through the modulation in the  electronic control unit, high precision square wave  signal is obtained.


Features:
