Introduction

Shen Zhen Zhuohe Instrumentation Co.,Ltd was founded in year of 2002, which was also called Shenzhen LongXin Zhiye Technology Co.,Ltd. We specialize in providing products, solutions and services of batching control, dynamic weighing and quantitative packing technology in the filed of construction, power supply, coal, metallurgy, chemical industry, food stuff, pharmaceutical and so on.

Weighing controller indicators we provide are A series batching scale controller, B series belt scale controller, C series packing scale controller, D series weight transmitter.

What is weighing controller
Weighing controller, also known as weighing controller indicators, is an electronic equipment that converts the signal of weighing sensor (or through weight transmitter) into weight digital display, and can store, count and print the weight data. It is often used for automatic batching and weighing in industrial and agricultural production to improve production efficiency.

Each weighing controller manufacturers design the instrument, the internal use of integrated circuit chip is a variety of, but the basic functional modules are the same.It is generally composed of the following modules: A/D conversion module, power module, CPU module, keyboard display module, communication module, printing, I/O module and so on.

What are the categories of weighing controller

Weighing controller can be divided into two categories according to their use, one is open loop control type, the other is closed loop control type.Open loop control type instrument only weighing display, without I/O function, mainly used for truck scale, ground scale, scale and other classes only required to display the weight of the weighing device.Closed-loop control indicators have I/O circuits that control the operation of external equipment according to the size of the weight.This kind of instrument is mainly used for packing scales, batching scales, filling scales and other industrial scales with external actuators.

Instrument calibration and calibration methods

Before use, the weighing controller should be equipped with the weighing sensor for digital calibration.Calibration is to calibrate the weighing controller with standard weights.Calibration coefficients relative to the set of sensors are stored in the calibrated instrument.With this factor, the meter can convert the sensor's analog signal into a digital weight display.Therefore, when one instrument in use is damaged, it cannot be replaced with another instrument of the same type that has not been calibrated.

In recent years, the emergence of digital meters is supporting the use of digital sensors.There is no A/D module in the instrument. A/D module is put in the sensor end.A digital instrument receives a digital signal from a sensor.The calibration method of digital instrument is different from that of ordinary weighing controller.
