8502-BI-DP  称重系统基于称重传感器

典型的称重系统由重量控制器、基于称重传感器的平台秤和可编程逻辑控制器组成。自20世纪70年代初以来，基于应变仪的称重传感器与过程称重仪器和控制系统的集成已经取得了长足的进步，当时典型的批量称重控制系统可以轻松地装满一个6英尺高、8英尺宽的机柜。

如今，带有内置重量转换器的小型可编程逻辑控制器(PLC)可以完成同样的任务。称重系统基于称重传感器，传感器将机械力(重量)转换为电信号。它们接收一个激励电压(5±15 VDC ),并产生一个与施加的重量(力)成比例的小模拟信号。重量转换器提供激励电压；接收、调节和数字化称重传感器的信号；并将重量值传送给PLC。然后，PLC监控重量，并通过打开和关闭闸门或阀门，或者打开或关闭泵或进料器来控制过程。让我们回顾一些过程称重应用及其要求。

The 8502-BI-DP weighing system is based on a weighing sensor

A typical weighing system consists of a weight controller, a platform scale based on a weight sensor and a programmable logic controller. The integration of strain gauge based load cells with process load cells and control systems has come a long way since the early 1970s, when a typical batch load control system could easily fill a cabinet 6 feet high and 8 feet wide.

Today, small programmable logic controllers (PLCS) with built-in weight converters can accomplish the same task. Weighing systems are based on weighing sensors that convert mechanical force (weight) into electrical signals. They receive an excitation voltage (5±15 VDC) and produce a small analog signal proportional to the applied weight (force). Weight converter provides excitation voltage; Receive, adjust and digitize the signal of the load cell; The weight value is transmitted to the PLC. The PLC then monitors the weight and controls the process by opening and closing the gate or valve, or opening or closing the pump or feeder. Let’s review some process weighing applications and their requirements.
Master board card modules are commonly used in industrial automation and control systems to process and control input/output signals. It is a digital input/output module that provides programmable functionality for monitoring and controlling external devices.
Modules typically provide multiple independent input/output channels for connecting external sensors, actuators, or other devices. These channels can process both digital input signals and digital output signals.
The module usually has flexible configuration and programmable functions, which users can customize and set according to actual needs. This enables the module to adapt to different application scenarios and control requirements.
