1. Product introduction

Small level switch is used for solid state (powder, block, granular, gel, etc.) level controller. It has good sealing, overload capacity is strong, lightweight installation, output electric shock characteristics such as large capacity, according to different proportion of material can be done by the spring tension, contact material part of its full stainless steel material, material level switch in chemical, plastic, cement, medicine, feed, food and other industries widely used. Material level signal device mainly exposed parts of the material, are stainless steel and aluminum alloy composition. It has the characteristics of corrosion resistance, moistureproof, dustproof and so on. It can be used in food industry or high dust evil slightly environment. The output shaft adopts overload protection device, which can effectively avoid the damage caused by improper use or abnormal external force to the motor and reducer. According to the needs of the user can provide two different installation mode, in order to adapt to the different proportion of various materials easy to use and adjust.

Two, the working principle

Resistant rotation material level switch is driven by AC micromotor after deceleration test blade slowly rotate. When the material level rises to prevent the rotation of the blade, the detection mechanism will rotate around the spindle. This displacement first a micro - switch action, issued a material signal. A second microswitch then acts, cutting off the power to the micromotor and stopping it.

Three, product characteristics

1, the shell is fully airtight, with dustproof performance. Fully sealed bearing, plus special oil seal, can prevent dust along the transmission shaft infiltration;

2, the tension spring is adjustable, can adapt to the measurement of various bulk density materials;

3, Motor separation structure, the overall disassembly free easy maintenance;

4, Clutch design, with overload protection function;

5, simple installation, and do not need to be removed from the warehouse wall, you can check and replace the internal parts.
