Microcontroller for Screw Conveyors MC 755B

MC 755B

The best continuous weighing system for conveyor belts, MC 755B allows you to precisely control the tons produced and record production in real time. Two different types of operation are available: flow rate reading and flow rate regulation. In both cases, the material passes over a weighed portion of the belt, whose dimensions, in addition to the speed of the belt itself, read by an encoder, allow the microprocessor to calculate the hourly flow rate and the total of the material passed. In the case of flow rate regulation, the terminal with optional analog output also regulates the belt speed and keeps the flow rate constant at the programmed value. PWS: 02/2025
