AP-981

The MP-981 is a magneto-type detector using a hall element which is suitable for revolution (r/min) measurement from low speed to high speed.

Magneto-type detectors use an internal hall element, a permanent magnet, DC amplifier, and voltage regulator and respond to flux, so that a rectangular wave form is derivable from much lower speed  all the way though high speed.
In addition, a signal indicator is provided in spite of the detector's compact design, making verification of operation and mounting position possible.

Meanwhile, the AP-981 is the water and acid proof type, which conforms to Class ' of JIS C0920.

 

Features

· Possible to measure broad speed range from lower speed almost 0 r/min (from 1 Hz) to higher speed

· Signal detection can be monitored checking the indicator on the body

· Water & acid proof (AP-981)
