Shandong Leheng Instrument Co., Ltd. is one of the most reliable manufacturers and suppliers of weighing scale controller in China. We ware committed to providing high quality customized products with low price. Please feel free to wholesale cheap weighing scale controller in stock here from our factory.
A weighing controller is an intelligent terminal device that integrates weighing signal processing and industrial automatic control functions. It is not only the data terminal of the weighing system, but also the execution center for industrial process control. In addition to receiving, processing, and displaying weighing sensor signals, it can also issue control commands to external actuators (such as feeding valves, packaging machines, alarms) through the built-in switch input/output interface based on preset quantitative values, upper and lower limits, and other parameters.
The product is widely used in automation scenarios such as quantitative packaging scales, ingredient scales, sorting scales, filling systems, belt scales, and process weighing control. It is a key equipment for achieving production automation in industries such as building materials, chemical, grain, and metallurgy.

Q6. How many sensors can be connected to the weighing controller?
It depends on the sensor excitation current capability of the controller. Generally, 4 sensors with an internal resistance of 350 Ω can be connected, and some models can connect up to 12 sensors with an internal resistance of 700 Ω. When multiple sensors are connected in parallel, they need to be connected through a junction box.
