Principle of Operation
操作原理
A mechanical vibrating system gets forced to vibrate on its resonance frequency by means of piezo electric crystals.機(jī)械振動(dòng)系統(tǒng)被強(qiáng)迫其共振頻率振動(dòng)的壓電晶體的手段。 When the vibrating blade gets covered by the material to be detected the vibration stops.當(dāng)振動(dòng)葉片被覆蓋的材料被檢測(cè)到的振動(dòng)停止。 This is sensed by an electronic circuit which forces a binary output to switch.這是由電子電路，這迫使二進(jìn)制輸出切換檢測(cè)。 When the blade gets uncovered the vibration restarts and the output switches back.當(dāng)?shù)镀话l(fā)現(xiàn)重新啟動(dòng)的振動(dòng)和輸出切換回。

The vibration technique has got many advantages over alternative level sensing technologies.
振動(dòng)技術(shù)替代水平的遙感技術(shù)得到了很多好處。
- unaffected by environmental changes eg temperature, pressure, humidity
不受環(huán)境變化的影響，例如溫度，壓力，濕度 - unaffected by material changes
不受重大變化 - unaffected by dust clouds and agitation
不受塵埃云和鼓動(dòng) - maximum versatility
*大的多功能性 - no calibration required
不要求校準(zhǔn) - no maintenance required: the vibration has a self cleaning effect
無(wú)需維護(hù)：振動(dòng)具有自清潔效果 - highest performance and durability: no moving parts, no wear-out
*高的性能和耐久性：無(wú)運(yùn)動(dòng)部件，無(wú)磨損，
Furthermore the PTL products offer the following advantages
此外，PTL的產(chǎn)品具有以下優(yōu)點(diǎn)
- highest sensitivity: even extremely light materials like styrofoam with densities down to 10 grams per litre and lower can be detected
*高靈敏度：密度下降到10克每升降低甚*輕如發(fā)泡膠材料可檢測(cè) - the unique, patented single rod designs with its specifically shaped vibrating blades prevent false signalling caused by material build-up, bridging and rat-holing.
