sa capacitance level switch principle the capacitance level sensor measuring principle is based on the physical properties of a capacitor formed by the sensor and the vessel wall, the electric capacity is affected by the dielectric value of products. when the sensor is not covered, the dielectric constants =1 (air is usually =1) when the sensor is covered, the dielectric constant will increase in capacity, the electronic oscillator (1 mega hz radio frequency) will cr-eate a resonating signal, which will turn the unit on or off for level control purpose. features and applicationsbecause the capacitance level sensor has no moving parts inside the device, it is will not be affected by friction. it is suitable for powder or liquid application easy to install. the customer can choose the types below to suit his requirements. 1. standard type(sa110 & sa111 a/b/c ) suitable for general use. 2. hi-temp type (sa120 & sa128 a/b/c) suitable for high temperature environment. 3. corrosion-proof type (sa130 & sa132 a/b/c) suitable for corrosive environment. 4. remote probe type(sa140 a/b/c)or use with vibrator equipped tank. 5. wire-probe type(sa150 a/b/c) suitable for silo or deeper tank. 6. plate-probe type (sa160 a/b/c)suitable for granules and at lower position of tank side. 7. explosion-proof type (sa170d ~ sa178d)with sa-75u can be use in hazardous areas. 8. anti-static type(sa180 & sa181 a/b/c) suitable for electrostatic environment (it won"t be damaged by the electrostatic discharge)

L60型射頻導(dǎo)納物位控制器 二次顯示配套控制儀:ACH6智能數(shù)顯控制詳見說明(第4頁) ◇ L60型采用了抗粘附電路,可以在探測真實物位的同時,清除粘附和懸掛在探頭周圍的假物位信號影響。L60型原理是基于射頻(RF)電容技術(shù)。因材料均有介電常數(shù),其導(dǎo)電率都不同于空氣,探頭與材料接觸時由于電容量偏移反映的總阻抗發(fā)生變化。因為通電的探頭和容器壁構(gòu)成電容器的二塊極板,探頭絕緣體和周圍空氣成為介電材料,電容值的變化造成了阻抗的變化,可檢測任何物料。L60型與LC86X型傳感探頭匹配。它能用于高溫、高壓環(huán)境,液體、粉體、大固體塊料及腐蝕性物體。技術(shù)參數(shù) 繼電器容量:DPDT,額定10A,115VA.C或5A,220VA.C物料溫度:-184℃~260℃ 延時:0~30″秒連續(xù)可調(diào) 電路耐溫:-40℃~80℃ 感應(yīng)度:0.5Pf失電保護:高低模式可調(diào) 電源:220VA.或24VD.外殼:IP65,重型鑄鋁外殼
