Belt scale - Zhongxin is a first-class company in the sales field of belt scale sensors

Guangzhou Zhongxin Automation Technology Co., Ltd. is a first-class company in the field of industrial weighing and accessories - belt weighers

1. The structure of belt weighers

electronic belt weighers, composed of steel mechanical weighers, speed sensors, high-precision weight sensors, electronic belt weigher control display instruments, etc., can continuously and dynamically measure solid materials< a>

2. Working Principle of Belt Scale

The weighing feeder will detect the weight of the material passing through the belt through the weighing sensor under the weighing scale frame to determine the weight of the material on the belt; A digital speed sensor installed on the tail drum or rotating equipment continuously measures the feeding speed, and the pulse output of the speed sensor is proportional to the belt speed; The speed signal and weight signal are sent together to the belt feeder controller to generate and display cumulative/instantaneous flow rate. The feeding controller compares the flow rate with the set flow rate, and the controller outputs a signal to control the frequency converter speed regulation, achieving the requirement of quantitative feeding. As shown in the following figure:

When weighing, the load-bearing device transfers the gravity of the material on the belt to the weighing sensor, which outputs a voltage (mV) signal proportional to the gravity of the material. After being amplified by an amplifier, it is sent to the analog-to-digital converter to convert it into a digital quantity A and sent to the arithmetic unit; After the material speed is input into the speed sensor, the speed sensor outputs pulse number B and also sends it to the arithmetic unit; After calculating A and B, the arithmetic unit obtains the amount of material for this measurement cycle. Accumulate each measurement cycle to obtain the total amount of material continuously passing through the belt< a>

There are two main types of weighing displays: digital display and Chinese character display. Chinese character display is an upgraded product of digital display. The weighing display has cumulative and instantaneous flow display, and has functions such as automatic zero adjustment, semi-automatic zero adjustment, self checking faults, digital calibration, flow control, printing, etc. In addition to this, Chinese character display can also display speed. Chinese character display has functional display during operation, which can better assist users in operation< a>
