<description><![CDATA[音叉物位开关是一种新型物位控制开关，它主要是靠音叉，通过震动原理来测量物位高度。音叉式物位控制器的工作原理是通过安装在音叉基座上的一对压电晶体使音叉在一定共振频率下振动。当音叉与被测介质相接触时，音叉的频率和振幅将改变，这些变化由智能电路来进行检测，处理并将之转换为一个开关信号。brbr音叉物位开关具有使用寿命长、性能稳定、安全可靠，以及适应性强、不需调校和免于维护等特点，主要广泛应用于冶金、建材、化工、轻工、粮食等行业中物位的过程控制。brbr它不受泡沫、涡流、气体的影响，适用于各种料仓固体物料料位以及各种容器内液位的定点报警或控制。brbr对固体物资，主要测量能自由流动的中等密度的固体粉末或颗粒。例如，粉煤灰、水泥、沙子，石粉、塑料颗粒、盐、糖等。brbr对液体物资，主要测量具有爆炸性和非爆炸性危险的液体，腐蚀性液体（酸、碱溶液等）高粘度液体水、酸、碱、泥浆、纸浆、染料、油类、牛奶、酒类、饮料等。音叉物位开关的应用较广，主要针对密度范围较宽的粉体、小颗粒料，如除尘器的进、出气管堵管检测，除尘器集灰斗料位测量，塑料，橡胶粉末，面粉，各种粮食作物，食品，化工产品等等限位测量。brbr针对各种性状的液体：如浆状、粘稠状、易起泡沫、腐蚀性等各种介质之限位检测。brbrbr应用：brbr各种料仓料位以及各种容器内液位的定点报警或控制brbr固体物料：米、奶粉、糖、盐、洗衣粉、染料、水泥、石粉、塑料颗粒等brbr液体介质：水、泥浆、纸浆、染料、油类、牛奶、酒类、饮料等brbr特性：brbr振幅可调，可测量不同状态和密度的物料brbr能检测液体中的沉淀物brbr防腐、灵敏度高brbr仪表无可动部分，安装方便brbrtableclass="MsoNormalTable"border="1"cellspacing="0"cellpadding="0"style="margin-left:1.45pt;border-collapse:collapse;border:none;height:378px;"tbodytrstyle="mso-yfti-irow:0;mso-yfti-firstrow:yes;page-break-inside:avoid;height:18.45pt;mso-height-rule:exactly"tdwidth="103"valign="top"style="width:77.6pt;border:1ptsolidwindowtext;background-color:white;padding:0cm;height:25px;background-position:initialinitial;background-repeat:initialinitial;"pclass="MsoNormal"align="center"style="text-align:center"bspanstyle="mso-bidi-font-size:10.5pt;font-family:幼圆"环境温度/span/bbspanlang="EN-US"style="font-family:幼圆"o:p/o:p/span/b/p/tdtdwidth="539"style="width:403.9pt;border-style:solidsolidsolidnone;border-top-color:windowtext;border-right-color:windowtext;border-bottom-color:windowtext;border-top-width:1pt;border-right-width:1pt;border-bottom-width:1pt;background-color:white;padding:0cm;height:25px;background-position:initialinitial;background-repeat:initialinitial;"pclass="MsoNormal"align="center"style="text-align:center;line-height:12.0pt;mso-line-height-rule:exactly"spanlang="EN-US"style="mso-bidi-font-size:10.5pt;font-family:幼圆"-25/spanspanlang="EN-US"-/spanst1:chmetcnvunitname="℃"sourcevalue="60"hasspace="False"negative="False"numbertype="1"tcsc="0"w:st="on"spanlang="EN-US"style="mso-bidi-font-size:10.5pt;font-family:幼圆"60/spanspanstyle="mso-bidi-font-size:10.5pt;font-family:幼圆"℃/span/st1:chmetcnvspanstyle="font-family:幼圆;mso-ansi-language:#0400;mso-fareast-language:#0400"o:p/o:p/span/p/td/trtrstyle="mso-yfti-irow:1;page-break-inside:avoid;height:18.45pt;mso-height-rule:exactly"tdwidth="103"valign="top"style="width:77.6pt;border-style:nonesolidsolid;border-right-color:windowtext;border-bottom-color:windowtext;border-left-color:windowtext;border-right-width:1pt;border-bottom-width:1pt;border-left-width:1pt;background-color:rgb(230,230,230);padding:0cm;height:25px;background-position:initialinitial;background-repeat:initialinitial;"pclass="MsoNormal"align="center"style="text-align:center"bspanstyle="mso-bidi-font-size:10.5pt;font-family:幼圆"探头材料/span/bbspanlang="EN-US"style="font-family:幼圆"o:p/o:p/span/b/p/tdtdwidth="539"style="width:403.9pt;border-style:nonesolidsolidnone;border-bottom-color:windowtext;border-bottom-width:1pt;border-right-color:windowtext;border-right-width:1pt;background-color:rgb(230,230,230);padding:0cm;height:25px;background-position:initialinitial;background-repeat:initialinitial;"pclass="MsoNormal"align="center"style="text-align:center;line-height:12.0pt;mso-line-height-rule:exactly"spanstyle="mso-bidi-font-size:10.5pt;font-family:幼圆"不锈钢spanlang="EN-US"(/span根据用户订货spanlang="EN-US")/span/spanspanstyle="font-family:幼圆;mso-ansi-language:#0400;mso-fareast-language:#0400"o:p/o:p/span/p/td/trtrstyle="mso-yfti-irow:2;page-break-inside:avoid;height:18.45pt;mso-height-rule:exactly"tdwidth="103"valign="top"style="width:77.6pt;border-style:nonesolidsolid;border-right-color:windowtext;border-bottom-color:windowtext;border-left-color:windowtext;border-right-width:1pt;border-bottom-width:1pt;border-left-width:1pt;background-color:white;padding:0cm;height:25px;background-position:initialinitial;background-repeat:initialinitial;"pclass="MsoNormal"align="center"style="text-align:center"bspanstyle="mso-bidi-font-size:10.5pt;font-family:幼圆"输出信号/span/bbspanlang="EN-US"style="font-family:幼圆"o:p/o:p/span/b/p/tdtdwidth="539"style="width:403.9pt;border-style:nonesolidsolidnone;border-bottom-color:windowtext;border-bottom-width:1pt;border-right-color:windowtext;border-right-width:1pt;background-color:white;padding:0cm;height:25px;background-position:initialinitial;background-repeat:initialinitial;"pclass="MsoNormal"align="center"style="text-align:center;line-height:12.0pt;mso-line-height-rule:exactly"spanlang="EN-US"style="mso-bidi-font-size:10.5pt;font-family:幼圆"2/spanspanstyle="mso-bidi-font-size:10.5pt;font-family:幼圆"组常开、常闭触点；spanlang="EN-US"0/10mA/span/spanspanstyle="font-family:幼圆;mso-ansi-language:#0400;mso-fareast-language:#0400"o:p/o:p/span/p/td/trtrstyle="mso-yfti-irow:3;page-break-inside:avoid;height:18.45pt;mso-height-rule:exactly"tdwidth="103"valign="top"style="width:77.6pt;border-style:nonesolidsolid;border-right-color:windowtext;border-bottom-color:windowtext;border-left-color:windowtex
