MP-9100

 

 

MP-900/9000 are chiefly used in conjunction with a detector gear mounted onto a rotating shaft by bringing the detector into proximity to the gear so that the detector outputs frequency signal of which is proportional to the rotational speed. So various types are available including low-priced, general purpose, oil proof and heat resistant types that you can make a choice for your usage.

Signal cables (except attached-cable types), extension cables and connectors are sold separately.

 

Features

  • Output is obtained by simply bringing them close to a gear.
  • Simple structure, rigid, and designed to be used in harsh environment. Not to be affected by vibration, temperature, oil and dust.
  • Non-contact detection makes measurement safe without applying load to rotational body.
  • No power supply is required and suitable to the field measurement.
  • 15 types are available including oil proof, high temperature, extra small and long-shape types.
