Electronic belt weigher - basic composition
(1) belt conveyor and its driving unit (although the manufacturers of embedded belt scales are generally not provided, but if the belt scale is not complete, it can not work properly.) Weighing unit, speed measuring unit, signal acquisition, processing and control unit.
For conveyor belt scales, the whole belt conveyer is the loader; for the weighing platform belt scale, its weighing and weighing roller and the conveyer belt that run just above it constitute the loader.
The weighing sensor is a component that converts the gravity of the said material into analog or digital electrical signals. The combination of weighing table and weighing sensor is often called weighing unit. The electronic belt weigher, as a dynamic measuring instrument, is also used to measure the speed of the said material.
Signal acquisition, processing, and control units are electronic devices used to receive and process electrical signals from the output of sensors, to give measurement results in units of quality, and to complete other predetermined functions. It can be a single instrument (such as a "dynamic weighing display controller"), or a combination of several independent parts (for example, a separate sensor to stimulate a power supply, a signal collector on the site, an integrator for a central control room and a upper computer, etc.). In order to describe the convenience, this volume tutorial often referred to signal acquisition, processing, and control unit (both single and combined) as "display control device".
