SZMB-9B magnetoelectric rotation speed sensor can counter the displacement into electrical signal for the count. Non-contact can measure a variety of magnetic materials such as: gears, impellers, with holes (or slots, screw) disc (or axis) of the speed and line speed. 

Sensors with intrinsic safety, small size, solid and reliable, long life, no power and lubricants, etc, and all associated equipment Zener gate post and the secondary instrument package may constitute intrinsically safe explosion-proof speed detection system

Output waveform: sine wave is approximately (≥ 50r/min pm) 

Output signal amplitude: 50r/min when ≥ 300mV
