西門子超聲波傳感器概述

超聲波物位測(cè)量系統(tǒng)是監(jiān)測(cè)和控制各種工


 業(yè)行業(yè)中從短到長(zhǎng)量程的液體、漿料和固體物位的經(jīng)濟(jì)選擇。

超聲波傳感器不受灰塵、濕氣、腐蝕、振動(dòng)、溢流和高溫的影響。它們安裝簡(jiǎn)單且免維護(hù)。各種型號(hào)可選,不管

 是長(zhǎng)距離應(yīng)用,還是短距離應(yīng)用,不管是液體,還是資料。

應(yīng)用

傳感器都可以裝入過(guò)程容器,可以用于有蒸汽和苛刻的化學(xué)腐蝕的場(chǎng)合,并且可以不用法蘭安裝。

XPS 系列的監(jiān)測(cè)距離zui大為 40米,使用溫度zui高達(dá) 95 °C。

在高溫測(cè)量場(chǎng)合,XCT 系列超聲波傳感器的可以監(jiān)測(cè)zui大為12米,使用溫度高達(dá) 145 °C。

運(yùn)行時(shí),Echomax 超聲波傳感器以一個(gè)窄的波束垂直于其表面發(fā)射

 聲音脈沖。液位變送器通過(guò)發(fā)射和回波之間的時(shí)間差來(lái)計(jì)算距離。

主要應(yīng)用:電力、石油、化工、采礦、鋼鐵、水泥、冶金、食品、造紙、醫(yī)藥、紡織、輕工、環(huán)保、水利等領(lǐng)域
