SZMB-5-B explosion-proof magneto electric speed sensor can convert angular displacement into electrical signals for counter counting. It can measure the speed and linear velocity of various magnetic materials such as gears, impellers, disks (or shafts) with holes (or slots, screws) without contact. It has the characteristics of small size, reliable structure, long service life, long transmission distance, and wide working environment temperature range. After being matched with the associated device Zener safety barrier (LB-867), it can form an "intrinsic safety explosion-proof magneto electric speed detection system" with secondary instruments, which can be used in various explosion-proof sites. Its explosion-proof mark is ibIIBT4
