Rotary resistance material level cement silo level switch stop rotating material level, a "level meter", "level switch", "level switch", "level meter", "Level sensors", etc., cement silo Level signal switch is mainly used for various materials (such as powder, granular or block) bunker material level limit detection and automatic control, material level of different models to meet different application requirements, in metallurgy, food , material handling and control procedures flour, building materials, cement, electricity, coal, chemical, foundry, rubber, environmental dust and other industries have a wide range of applications. Resistance rotary level meter is widely used in modern industrial processes and warehousing sectors. Resistance rotary level meter has the following features: 1. Full airtight shell, waterproof and dustproof performance. 2. Fully sealed bearings, plus a special seal to prevent infiltration of dust along the shaft. 3. The tension springs adjustable, can be adapted to measure a variety of bulk density materials. The unique clutch design, with overload protection. 5. Installation is simple, and does not have to be removed from the warehouse wall, you can check, replacement of internal parts. Resistance rotary level meter installation requirements: 1. In the coupling position of cutting a hole φ60mm, the coupling insert screw clamps 1/3, welding solid 2. Level the instrument insert and tighten the screw clamps must be made and outlet down, then Mother with back fastening wiring diagram. WAM rotary type level alarm for spot measurements bunker material level, it has anti-adhesive, high temperature, adjustable sensitivity and other characteristics.
