cn WEB:www.sensorway.cn 概述 射频电容物位控制器是基于射频(美国 PRINCO)技术研究而成的,防 粘附、 更可靠, 适用性更广的物位控制器: 将一高频无线电波施加在探头上, 当物料位置发生变化时,仪表的探头和容器壁以及被测物料形成导纳值相应 发生变化,这一变化被电路检测后通过仪表内的变化,并转换成相关的信号 输出供远程控制或报警使用.仪表独特的电路设计(利用等电位原理),可 以使测量电路彻底消除探头上物料的堆积对测量的影响,从而正确反映出实 际的物位而不是粘附在探头堆积的物料. 产品特点 ? 通用性强: 可应用于各种导电和非导电介质的测量, 例如液体、 粘稠物、 颗粒、粉末、飞灰. ? 可抗粘附:采用抗粘附电路,可以消除因物料粘附而产生的虚假信号. ? 探头可拆:控制器与探头之间没有电缆连接,随时可以将控制器拆除更 换维修,不影响进出物料. ? 耐高低温:适用于-184℃至280℃的工作环境,另可提供适用于更高温度的陶瓷探头. ? 输出形式:采用双刀双掷的继电器信号输出,同时有状态灯显示输出状态,并有

0 至30 秒的延时功能. 产品参数 ? 电源电压:220VAC/24VAC/24VDC ? 功率:4W ? 继电器输出:5A/240VAC,两组常开、常闭触点 ? 灵敏度:0.3pf-750pf ? 探头材质:SUS304/SUS316/Teflon ? 环境温度:-40-80 ? 延迟时间:0-30 秒可调 ? 工作温度:-180-250(超高温可达 1000) ? 连接螺纹:NPT1''(特殊规格可定制) 外形尺寸 射频导纳物位开关 RF Admittance Level Switch 北京赛斯维测控技术有限公司 TEL:010-84775646 FAX:010-58949029 E-MAIL: sales@sensorway.cn WEB:www.sensorway.cn 订购信息 北京赛斯维测控技术有限公司 地址:北京市朝阳区望京西路48号金隅国际D座302
