What Is A Weighing Controller ? What Is The Use of The Weighing Controller ?

Weighing controller, also known as weighing controller indicator transmitter, 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 instrument 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 instruments

Weighing instruments 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 meters 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 instrument should be equipped with the weighing sensor for digital calibration.Calibration is to calibrate the weighing instrument 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 instrument.

The model of weighing instrument is: XK31XX T600/800 GM8802/03/04/06, etc

Because the last two numbers are defined by the manufacturers themselves, there are some instruments of the same model but different manufacturers in the domestic market, and the functions of the same type of instrument are often different.

The advantages and disadvantages of multi-function weighing meter and single function meter

Multi-function weighing instrument: it has strong adaptability, can be widely used in a variety of non-automatic electronic weighing apparatus and automatic electronic weighing apparatus.But the software development cycle is long and the hardware support cost is high, so its manufacturing cost is high.

Single function meter: software development cycle is shorter, hardware is less, so its manufacturing cost is lower.

Special instrument;The manufacturing cost is between single function and multi-function.In terms of the use failure rate, by contrast, the multi-function is higher.

What are the problems to consider when choosing instrument

A, choose which type of instrument should be based on actual needs, rather than choose the more functions, the better;

B. Select the products with the production license of measuring instruments;

C. All technical indicators meet the national standard of weighing display controller;

D, the focus should be to check whether it meets the safety protection requirements;

What are the manufacturers of weighing instruments

China's weighing instrument manufacturers have reached hundreds of manufacturers, among which the better-known are shenzhen longson wisdom industry, Shanghai Toledo, Germany Siemens and so on.

International and domestic weighing instrument dynamics

At present, the domestic development and production of the instrument is generally only equipped with one scale, and the foreign production of the instrument can be equipped with a table at the same time with more than one scale.Its software functionality and hardware support can be shared, thus relatively reducing manufacturing costs and administrative overhead in use.
