Working principle of batching scale instrument

The batching scale instrument collects the analog signal output by the sensor. After the data is integrated and processed by the imported chip, the weight value of the material to be weighed is displayed by LED. The weight value of the material is displayed at the same time after high-speed calculation by the computer program and the set value. Comparison, if the weight value reaches the set value, the controller will output a signal to the control equipment, so as to realize intelligent actions such as stopping feeding and dropping the belt.

The batching weighing system is a system that controls the weighing and measuring work of the tank through the combination of sensors, instruments and control systems.

Functional characteristics of batching scale instrument

All keyboard digital adjustment and working parameter setting have calibration, pre-feeder control, communication function, printer serial interface (RS232) serial host interface (RS232) 2 channels AD (analog input) 2 channels DA (analog output: 020mA) 2 digital inputs (24V, 5mA) Fault-protected storage (EEPROM) Complete diagnostic and self-checking functions (SPC) High electromagnetic compatibility, electromagnetic isolation output contacts Factory presets, convenient, quick and easy debugging Automatic calibration program , without manual intervention to calculate the range range status, events, calibration and cumulative output with self-test and self-learning functions.

Dosing scale meterTurn on the power supply, after the signal retrieval is completed, preheat for 30 minutes. Press the "Start\/Stop" button, - the start\/stop indicator light is on, the entrainment can be started to work, - the coarse flow, - the fine flow indicator light is on, and the output control signal, When the weight reaches the set value, the corresponding -coarse flow and -thin flow indicators are off, and the output control signal is stopped. After that - the bag push indicator light is on and the bag push signal is output, and a working cycle is completed.
