RF805G3A Radio Frequency Admittance Level Switch Introduction
The RF805G3A is an advanced level switch utilizing radio frequency (RF) admittance technology, designed for point-level detection of liquids, solids, and adhesive materials. It employs a high-frequency electronic circuit and three-electrode system (measuring electrode, shield electrode, and ground) to analyze changes in capacitance and conductance caused by material dielectric properties, ensuring accurate level monitoring. Key features include anti-coating capability, which minimizes false signals from material buildup, and broad applicability across industries such as petroleum, chemical processing, metallurgy, and food production. The switch supports flexible installation via 3/4" NPT thread or flange connections, with probe options of 316 stainless steel, ceramic, or high-temperature plastic for environments ranging from -40℃ to +500℃. Its relay outputs (SPDT) facilitate integration with PLC or DCS systems for automated process control. The design emphasizes reliability and ease of use in challenging industrial conditions.135
技术特点与工作原理
RF805G3A通过相位检测技术处理物料介电特性变化,结合Cote-Shield技术消除挂料干扰。电子单元产生的高频信号经探头反馈后,由内部电路解析相位差并触发继电器动作。其分体型结构(传感器+控制仪表)增强抗干扰能力,适用于高粉尘或腐蚀性环境。典型应用包括料仓堵料报警、油水界面检测等。2713
Technical Features & Operating Principle
The RF805G3A utilizes phase detection to process dielectric variations, with Cote-Shield technology eliminating coating interference. A high-frequency signal generated by the electronic unit is reflected via the probe, and the phase shift is analyzed to trigger relay outputs. Its split design (sensor + controller) enhances resistance to dust and corrosion, ideal for silo overfill prevention or liquid interface measurement. The robust construction ensures stable performance in harsh settings.41222

一、产品简介:
阻旋开关是用于固态物料(包括粉状、块状、粒状、胶状等)的物位控制器。它具有密封性好、过载能力强、轻便易装、输出触点容量大等特点。针对不同比重的物料可通过调弹簧的拉力来实现,其接触物料部分全为不锈钢材料。阻旋开关在化工、塑料、水泥、制药、饲料、食品等行业得到了广泛的应用。
二、工作原理
电机带动叶片旋转,当被侧介质到达叶片位置时,叶片手足停止转动,从而触动后面的微动开关输出开关信号,当被测介质下降离开叶片时,叶片在弹簧的作用下恢复原位继续转动。弹簧的拉力可根据所测介质的比重进行调整,物料比重大时弹簧调整到*强,反之调至*弱。
