485變送器

產(chǎn)品描述

參數

本變送器是數字稱(chēng)重變送器，該變送器可直接接入惠斯登電阻橋式拉／壓力傳感器，通過(guò)內部信號放大電路和 AD 采集電路等把傳感器的微電

壓模擬信號轉換為數字信號，模塊內置的微處理器支持校準算法，經(jīng)過(guò)校準操作后，可以直接從 485接口讀取到實(shí)時(shí)重量值。模塊輸出的485 接口

支持 Modbus-RTU 協(xié)議。

該產(chǎn)品適用于◇稱(chēng)重配料、測力等多種工業(yè)場(chǎng)合，標準 M odbus - RTU 通信協(xié)議使得模塊可以方便的與 PLC,DCS ，微機等設備連接到一起◇

作為稱(chēng)重前端信號處理模塊
