動態(tài)軌道衡信號通道

Weighing Channel of Automatic Railway Scale

       百靈軌道衡信號通道采用智能、模塊化設(shè)計，為動態(tài)電子軌道衡的專用稱重儀表，采用光電隔離技術(shù)，方便與計算機(jī)進(jìn)行通信，系統(tǒng)可靠性強(qiáng)。配備的擴(kuò)展開關(guān)暈輸入和輸出電路，適合各種現(xiàn)場需要。通信接口可采用光隔離遠(yuǎn)程驅(qū)動器，傳輸距離可達(dá)5-10公里。作為電子軌道衡的主要部件之一，它首先將傳感器的微弱重量信號進(jìn)行放大、濾波，然后經(jīng)模數(shù)轉(zhuǎn)換器將模擬量轉(zhuǎn)換成數(shù)字量送至計算機(jī)進(jìn)行處理。具有高分辨率、高轉(zhuǎn)換速度和長期工作穩(wěn)定可靠等特點(diǎn)。

Braun track scale signal channel by intelligent. modular design. for the dynamic electronic track scale special weighing instrument. adopt photoelectric isolated technology, convenient and computer communication, the system reliability Wiih the expansion of switch input and output circuit. suitable for all kinds of needs of field The communication interface with optical isolation distance drive. transmission distance up i0 5-10 km.As one of the main components of electronic track scale. it will first faint weight signal sensor are amplified and filtered. and then through an analogtodigital converter to convert analog signal into digital signal is sent to the computer for processing Has the advantages of high resolution. high conversIon speed and long-term stable and reliable work etc
