Belt Conveyor weightometers are required to accurately weight and chart the tonnage throughput. An operator is able to catch many problems that are developing simply by watching the tonnage. A drop or increase in tonnage can indicate something going wrong .within the system. MAGNETS, These capture what is known as "TRAMP METAL". This …
A speed sensor moni-tors conveyor belt speed for input to the integrator. The MMI is installed in a simple drop-in operation and may be secured with just eight bolts and existing idler sets, secured to the dynamic beam. With no moving parts, maintenance is kept to a minimum, with just periodic calibration checks required. Siemens 2022. 4.
A typical conveyor belt scale or belt weigher system has a weigh bridge structure supported on load cells, an electronic integrator, and a belt speed sensor. The load cells measure the material weight on the belt, and send a signal to the integrator. The integrator also receives input in the form of electrical pulses from a belt speed sensor.

The Smart Belt Scale is a conveyor belt scale specially designed for rugged outdoor environments such as quarries, gravel processing and mining. It is also well suited for any manufacturing process using conveyor belts, including: cement, fertilizer, chemical, tobacco, agro-food, etc…. It is designed for easy installation which can be done by ...
The force seen by the scale is proportional to the actual weight times the cosine of the conveyor angle. A level conveyor has an angle of zero degrees (Cos. (0)=1). Therefore, the force of gravity and the resultant force on the scale would be the same. A 40-pound weight would have a measured force equal to 40 pounds.
