An overview of the basic functions of the force measuring instrument

2019-12-16

The force measuring instrument is suitable for industries such as medicine, fine chemicals, cosmetics, light industry, batteries, health products, food, precision machining, etc. that require precise weight detection. The force measuring instrument detects the production line by high-speed dynamic weight reading. It can accurately detect the unqualified products in the continuous production line according to the weight of the products on the upper and lower lines, and then perform the control of upper and lower line discrimination or automatic weight sorting, especially suitable for the inspection of missing parts in the packaged products. The packaged products pass the inspection. Weighing and testing by weighing scales, the qualified ones are returned to the original conveyor belt, and the unqualified ones are rejected (or alarmed and stopped), and it has the functions of classifying and counting products according to the settings.

The basic function of the force measuring instrument is to convert the analog signal of the load cell into a digital weight signal; then through dynamic digital filtering and static digital filtering, the digital weight signal responds faster and more accurately, and the digital weight signal can be sent out through the serial port; At the same time, the digital weight signal is converted into an analog 4-20mA current signal or a 0-5(10)V voltage signal through D\/A conversion (optional function). The module has RS485 and RS232 dual communication interfaces, and supports standard MODBUS RTU communication Protocol and continuous output mode, can communicate with computer, PLC and other host computers, and can also be connected to a large screen. PLAC-5100-S includes a main board and an expansion board (optional). The expansion board mainly expands the switch input and switch output functions. , making up to 4 inputs and 7 outputs.

1, Comprehensive accuracy: ±0.01℅;

2. The display is a 2-line digital display, showing the instantaneous amount and the set amount;

3, a variety of calibration methods, can automatically adjust the zero point, automatic zero point tracking;

4. The remote counting adopts the form of non-contact, and outputs AC or DC signal;

5, Communication interface (optional): standard RS232C, RS485C interface;

6. Large-capacity record detection data, and save the data and the output interface can be connected to the computer for data transmission; group selection, set formula and set password protection;

7. Force measuring instrument display and control as well as multi-material batching, fixed value control, quantitative packaging or filling and other weighing control. It adopts a variety of original dynamic digital filters to quickly filter out various electromagnetic interference and mechanical disturbances.
