Introduction to Weighing System Configuration

The weighing system is generally divided into two parts, the signal acquisition part and the signal processing and display part. The signal acquisition part is generally achieved through sensors or transmitters, and the accuracy of signal acquisition is crucial for the weighing accuracy of the loader. The display section includes the display instrument.

A typical weighing system includes sensors, transmitters, instruments, and junction boxes. It is also a component that most customers need to match with sensors.

Weighing system configuration

The weighing system includes digital weighing and analog weighing systems.

1. Analog weighing requires the use of matching analog signal sensors, analog transmitters, analog junction boxes, and analog signal instruments.

For example, C16A+RM4220+WE2007+VKK1

2. Digital weighing requires the use of digital signal sensors, digital junction boxes, digital transmitters, and digital instruments.

For example, C16i+AE301+DIS2116+VKR

Note: Some high-end instruments can have both analog and digital outputs.

Sensors control the signal acquisition of the system.

Suitable ranges, materials, accuracy, and performance should be selected based on the installation environment and customer requirements.

Weighing configuration-Weighing instrument

Weighing instrument, also known as weighing display control instrument, is an electronic device that converts the weighing sensor signal (or through a weight transmitter) into a weight digital display, and can store, statistics, and print weight data. It is commonly used in automated batching and weighing in industrial and agricultural production to improve production efficiency.
　
Weighing instrument

Weighing instruments can be divided into display instruments and control instruments with communication functions.

The display instrument has simple functions, and the domestic price is usually within 1000 yuan, while the imported brand is within 2500 yuan.

Control instruments are mainly used in automation systems. In addition to the standard RS232 interface, they also include output interfaces such as PLC control, including I/O relay output, 4-20MA analog output, 0-10V output, AB RIO bus, Profibus DP bus, CC link interface, and DeviceNet bus interface.

The above aspects need to be considered for customers who choose and inquire. Interfaces are usually sold as options.

Weighing configuration-Weighing transmitter

A weighing transmitter, also known as a weight transmitter, is also known as an amplifier by some manufacturers. It is a type of transmitter that converts physical quantities into electrical signals, and isolates and amplifies the sensor output from the millivolt signal to convert it into a standard DC signal. Usually using the SMT process, designed and manufactured for resistance strain signal sensors in industrial processes, suitable for weighing sensors of different specifications.

Optional outputs: 4-20MA, 0-10V, 0-5V,& Plusmn; 5V. Choose according to the actual requirements of the customer.

system configuration-Junction box

Due to the unsatisfactory consistency of sensors when leaving the factory, coupled with limitations in the on-site environment and installation methods, multiple sensors are connected in parallel to form a balance. To solve the above problems, it is necessary to choose a junction box to adjust the consistency of sensors to ensure the balance of the entire scale body.
