The PLR-DS and PLR-DB converters, as well as the electronic belt scales, are measuring devices that enable continuous and automatic weighing of materials during their transportation by belt conveyors. Their main feature is that the weighing process is carried out continuously and automatically, usually without the need for human intervention. Electronic belt scales are primarily composed of three main components: sensors, the scale frame, and secondary instruments. The 6301D accumulator belongs to the category of secondary instruments. The 6301D accumulator is a type of instrument used in belt scales. Its distinctive feature is that it includes a digital conversion module that is installed at the site of the belt scale. This module converts the analog signals from the weighing sensors into digital signals, which are then transmitted to the instrument via RS485 communication. This design eliminates the problem of analog signals being easily affected by interference. The 6301D accumulator is available in both embedded and wall-mounted versions. By processing the weight signals from the weighing sensors and the speed signals from the speed sensors, it calculates the instantaneous flow rate and the cumulative amount of materials being transported, and displays these values on the instrument. Features: (a) Display of menus in both Chinese and English. (b) Weighing functions: · The AD module can be connected to up to 4 loads with a resistance of 350Ω simultaneously. It also receives signals from the speed sensors, allowing for the calculation of the flow rate and the cumulative amount of materials. · The accumulator is capable of performing automatic zero-point calibration.
