8502-BI-DP? 稱重系統(tǒng)基于稱重傳感器

典型的稱重系統(tǒng)由重量控制器、基于稱重傳感器的平臺秤和可編程邏輯控制器組成。自20世紀(jì)70年代初以來，基于應(yīng)變儀的稱重傳感器與過程稱重儀器和控制系統(tǒng)的集成已經(jīng)取得了長足的進步，當(dāng)時典型的批量稱重控制系統(tǒng)可以輕松地裝滿一個6英尺高、8英尺寬的機柜。

如今，帶有內(nèi)置重量轉(zhuǎn)換器的小型可編程邏輯控制器(PLC)可以完成同樣的任務(wù)。稱重系統(tǒng)基于稱重傳感器，傳感器將機械力(重量)轉(zhuǎn)換為電信號。它們接收一個激勵電壓(5±15 VDC ),并產(chǎn)生一個與施加的重量(力)成比例的小模擬信號。重量轉(zhuǎn)換器提供激勵電壓；接收、調(diào)節(jié)和數(shù)字化稱重傳感器的信號；并將重量值傳送給PLC。然后，PLC監(jiān)控重量，并通過打開和關(guān)閉閘門或閥門，或者打開或關(guān)閉泵或進料器來控制過程。讓我們回顧一些過程稱重應(yīng)用及其要求。

主板卡件模塊通常用于工業(yè)自動化和控制系統(tǒng)中，用于處理和控制輸入/輸出信號。它是一種數(shù)字輸入/輸出模塊，提供了可編程的功能，用于監(jiān)測和控制外部設(shè)備。
模塊通常提供多個獨立的輸入/輸出通道，用于連接外部傳感器、執(zhí)行器或其他設(shè)備。這些通道可以處理數(shù)字輸入信號和數(shù)字輸出信號。
該模塊通常具有靈活的配置和可編程功能，用戶可以根據(jù)實際需求進行定制和設(shè)置。這使得模塊能夠適應(yīng)不同的應(yīng)用場景和控制要求。

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.
