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
技術特點與工作原理
RF805G3A通過相位檢測技術處理物料介電特性變化,結合Cote-Shield技術消除掛料干擾。電子單元產(chǎn)生的高頻信號經(jīng)探頭反饋后,由內(nèi)部電路解析相位差并觸發(fā)繼電器動作。其分體型結構(傳感器+控制儀表)增強抗干擾能力,適用于高粉塵或腐蝕性環(huán)境。典型應用包括料倉堵料報警、油水界面檢測等。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、產(chǎn)品簡介:
阻旋開關是用于固態(tài)物料(包括粉狀、塊狀、粒狀、膠狀等)的物位控制器。它具有密封性好、過載能力強、輕便易裝、輸出觸點容量大等特點。針對不同比重的物料可通過調(diào)彈簧的拉力來實現(xiàn),其接觸物料部分全為不銹鋼材料。阻旋開關在化工、塑料、水泥、制藥、飼料、食品等行業(yè)得到了廣泛的應用。
二、工作原理
電機帶動葉片旋轉(zhuǎn),當被側介質(zhì)到達葉片位置時,葉片手足停止轉(zhuǎn)動,從而觸動后面的微動開關輸出開關信號,當被測介質(zhì)下降離開葉片時,葉片在彈簧的作用下恢復原位繼續(xù)轉(zhuǎn)動。彈簧的拉力可根據(jù)所測介質(zhì)的比重進行調(diào)整,物料比重大時彈簧調(diào)整到*強,反之調(diào)至*弱。
