产品描述
LS-DCA型射频电容式物位限位开关（下
称限位开关）是一种新型的物位仪表。

由于采用了“射频技术”和“数码标定技术”，解决了长期以来电容式物位限位开关在使用中温漂大、不易标定的两大难题，特别是“数码标定技术”属国内外首创,它必将推动电容式物位限位开关更广泛地应用于各行各业。

本物位限位开关可对块状、颗粒状、粉末状及液态物料料仓的料位及液位进行控制或上、下限位报警，适用于高温、高压、强腐蚀、多粉尘的恶劣环境；在冶金、石油、化工、轻工、煤炭、水泥、粮食等行业中应用广泛。

工作原理
当传感器安装于仓体上时，探极和仓壁分别相当于电容器的两个极板；由于被测物料的介电常数与空气不同，所以仓内物位发生变化时会引起探极对仓壁间的电容量发生变化，当该电容量大于用户的设定值时，限位开关内的继电器动作，输出一个开关量达到控制（或报警）的目的。

仪表的接线
上/下限位选择
接线端子
仪表面板分布图 ◆接线端子——端子“1”、“2”接AC 220V 或DC 24V 电源，端子“3”、“4”为继电器接点输出。

◆上/下限位选择——上/下限位由拨动开关设置，开关拨至右边为 “上限位”状态，输出继电器为有料吸合；开关拨至左边为 “下限位”状态，输出继电器为空料吸合。

出厂设置为上限位。

调试方法
用户应在确定传感器探头未被物料埋没条件下进行标定，具体标定步骤如下：
第一步：确认探头未被物料埋没（空仓或物料距离探头50cm 以上），上电30分钟。

第二步：观察 “频率显示值”并记录此数值。

第三步：用该“频率显示值”减去50便得出“动作频率值”；然后用小改锥将“动作频率值”设置到
“动作频率设定”旋转数码开关上，至此标定结束。

注：如传感器作为下限位检测，将“上/下限位”选择开关置于下限位位置。

安装方法
如安装示意图所示，限位开关通常采用侧装（在仓壁侧面安装）方式安装于仓体侧壁对料位高度进行上下限位置的检测，当仓体不便侧面开孔时可采用顶装（在仓的顶部
安装）方式。

顶装时电极距仓壁距离应大于200mm,应选择能避开进料时物料冲击的位置。

仓壁为混凝土时应使限位开关外壳可
靠接通钢筋，仓壁为非金属时应加装辅助探极（对于固体物料）或使用同轴探极（对于液体）。

注:用户拆装限位开关时禁止用手抱住壳体
拧动，应使用扳手拧动六角螺栓。
