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(shù)特點(diǎn)與工作原理
RF805G3A通過(guò)相位檢測(cè)技術(shù)處理物料介電特性變化，結(jié)合Cote-Shield技術(shù)消除掛料干擾。電子單元產(chǎn)生的高頻信號(hào)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(dòng)作。其分體型結(jié)構(gòu)（傳感器+控制儀表）增強(qiáng)抗干擾能力，適用于高粉塵或腐蝕性環(huán)境。典型應(yīng)用包括料倉(cāng)堵料報(bào)警、油水界面檢測(cè)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
