RF805G3A提供標(biāo)準(zhǔn)型、重型探頭型及耐高溫陶瓷探頭型等多種配置,探頭材質(zhì)可選316不銹鋼、四氟乙烯或陶瓷,適應(yīng)-180℃至+500℃介質(zhì)溫度。產(chǎn)品安裝方式靈活,支持3/4"NPT螺紋、法蘭等連接形式,防護(hù)等級(jí)達(dá)IP65。其校準(zhǔn)過程簡(jiǎn)便快捷,通用性強(qiáng),可與PLC或DCS系統(tǒng)聯(lián)動(dòng)實(shí)現(xiàn)自動(dòng)化控制。典型應(yīng)用包括料倉(cāng)堵料報(bào)警、液體界面檢測(cè)(如油水分離)及粉體物料監(jiān)控等場(chǎng)景。4914
英文介紹(Product Description)
The RF805G3A RF admittance level switch employs advanced radio frequency technology to detect liquid, solid and slurry levels in industrial processes. Its working principle is based on measuring the admittance change caused by material dielectric properties, which combines capacitance, resistance and inductance parameters for higher accuracy. The three-electrode design with shielded probe effectively eliminates false signals from material buildup, ensuring reliable operation in sticky or dusty environments like cement silos or chemical reactors. 723
Key features include multiple probe options (standard/heavy-duty/ceramic), broad temperature tolerance (-180°C to +500°C), and threaded/flange mounting configurations. The device provides DPDT relay output for easy integration with control systems. Typical applications span across bulk material monitoring in power plants, interface detection in oil-water separators, and powder level control in food processing. With IP65 protection and phase detection technology, it maintains stable performance under challenging conditions including high pressure and corrosive media. 21127
