SZMB-5B explosion-proof magnetoelectric rotation speed sensor, angular displacement can convert the signal for the counter is counting, 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. Small in size, structure, reliable, long life and long transmission distance, the working environment temperature range and so on. And all associated equipment Zener gate (LB-867) after matching, and the second instrument may constitute "intrinsically safe explosion-proof magnetic speed measuring system", for a variety of explosion scene, the explosion logo ibIIBT4.
