Product Overview
The APX501 tuning fork level switch is a high-performance detection device based on piezoelectric crystal and fork resonance principle, designed for liquid, granular solid, slurry, and powdered material level control. By monitoring frequency and phase changes of the vibrating fork, it delivers accurate switching signals through integrated circuit processing. Widely applied in automation systems for chemical, pharmaceutical, food processing, papermaking, and metallurgical industries, this device maintains stable performance even in harsh environments without requiring calibration or maintenance after installation. 157
Technical Features
Constructed with 316 stainless steel or Hastelloy fork material, the APX501 withstands corrosive media and operates reliably within -40℃ to 180℃. It offers dual power options (24VDC/220VAC) with standard DPDT relay output, featuring adjustable sensitivity and delay time. The compact fork design (minimum 40mm length) suits pipeline or confined space installations, accurately detecting low-density media (≥0.5g/cm³) including aggressive fluids like acids, alkalis, and frothy liquids. Integrated LED indicators provide real-time operational status. 3612
Operating Principle
Material contact alters the resonant frequency driven by piezoelectric crystals, which is instantly converted into switching signals by onboard smart circuitry. This mechanism ensures immunity to flow turbulence, bubbles, coating, or mechanical vibrations. For solids like cement or plastic pellets, adjustable amplitude accommodates varying densities; for viscous liquids such as syrups, the quick-drain fork design enhances response speed. 21114
Applications
Typical uses include compressor oil sump monitoring, high/low level alarms in petrochemical tanks, reactor vessel control in pharmaceuticals, and liquid process management in food production. It handles granular materials (e.g., grains, sugar) and diverse liquids (water, slurries, oils) with equal efficacy. Available with threaded or flanged connections, the switch supports horizontal/vertical mounting, while sanitary fittings meet food-grade requirements. 101630
APX501料位開(kāi)關(guān)
APX501
產(chǎn)品描述
阻旋料位開(kāi)關(guān)也有的稱之為阻旋物位計(jì)或者阻旋料位開(kāi)關(guān)、阻旋物位開(kāi)關(guān)等，主要是根據(jù)它具體的不同用途的不同名稱。阻旋式料位開(kāi)關(guān)是采用交流微電機(jī)經(jīng)減速后，帶動(dòng)檢測(cè)葉片慢速旋轉(zhuǎn)。當(dāng)被測(cè)物料的料位上升使葉片的轉(zhuǎn)動(dòng)受到阻擋時(shí)，檢測(cè)機(jī)構(gòu)主軸產(chǎn)生旋轉(zhuǎn)位移。此位移先使一個(gè)微動(dòng)開(kāi)關(guān)動(dòng)作，發(fā)出有料的信號(hào)。隨后另一個(gè)微動(dòng)開(kāi)關(guān)動(dòng)作，切斷微電機(jī)的電源使其停止轉(zhuǎn)動(dòng)。只要倉(cāng)內(nèi)的料位不變，此種狀態(tài)便將一直保持下去。
