Instruments & Meters

Belt weigher, manufactured and installed on conveyor belt, is used for weighing and measuring of continuous material flow and cumulant. It has features of high accuracy, reliability and meeting the needs of various poor environment industry occasions. It is widely used for industries of building material, chemical, metallurgy, coal, grain, forage and electric power, etc.

1. Main features:
1.1 Weighing range: 0.1~5000t/h；
1.2 Weighing mode: single idler, double idlers, multi idlers;
1.3 Weighing accuracy: ±0.25%；
1.4 Max inclination and idler grooved angle of belt conveyor: incl ination: 0°~18°; grooved angle: 0°~30°;
1.5 Istrument display instantaneous flow rate, cumulant and signal remote transmission ;
1.6 Realize batch dosed feeding;
1.7 Alarm for overrun of belt load;
1.8 In the condition of power off, the data in memory storage will be saved for ever.
1.9 Operation environment: instrument: -10~50℃; scale frame: -30~50℃；relative humidity: ≤90%；power supply: 220VC+10%-15%，50Hz±2%；

2. Working theory:
Belt weigher is used for weighing measurement of various flow rate and continuous material.
The load cell gets some belt load, the longer the measuring section belt length is, the less measuring result will be affected by environment. Load cell measure the belt load, and speed sensor measure the speed of belt. These two variables multiply and get the instantaneous flow rate. Then the accumulation of instantaneous flow rate will get the total amount of conveying material.

3. Structure features:
3.1 The material load on belt will be added directly to load cell (no lever ratio);
3.2 Weighing facility is two sets of stainless steel parallel spring leaf connecting with fixed frame, the spring leaf perform the function of fulcrum, no wear, less maintenance, high accuracy and reliable.
3.3 Fixed on belt conveyor frame by 4 support screw, no need change the frame of belt conveyor, easy to install, adjust and remove.
