技術(shù)特點(diǎn)
該料位開(kāi)關(guān)采用無(wú)活動(dòng)部件的機(jī)械結(jié)構(gòu)，具有免維護(hù)、長(zhǎng)壽命的特點(diǎn)。叉體長(zhǎng)度支持128mm至200mm定制延長(zhǎng)，工作溫度覆蓋-40℃至220℃范圍，提供AC220V或DC24V供電選項(xiàng)。過(guò)程連接支持螺紋和法蘭兩種方式，輸出為繼電器開(kāi)關(guān)信號(hào)。產(chǎn)品特別設(shè)計(jì)防掛料結(jié)構(gòu)，適用于粘稠液體或易附著物料的工況，且不受介質(zhì)電導(dǎo)率、介電常數(shù)等參數(shù)影響。17
工作原理
SP-YC71S通過(guò)壓電晶片激勵(lì)音叉產(chǎn)生固定頻率振動(dòng)，當(dāng)物料接觸叉體時(shí)振動(dòng)能量被吸收導(dǎo)致振幅衰減，內(nèi)置智能電路檢測(cè)該變化并轉(zhuǎn)換為開(kāi)關(guān)量輸出。共振頻率設(shè)計(jì)使探頭對(duì)物料接觸高度敏感，同時(shí)叉體前段至底座采用靈敏度梯度設(shè)計(jì)，有效避免物料堆積造成的誤觸發(fā)。該原理確保在復(fù)雜工況下仍能保持穩(wěn)定檢測(cè)性能。116

Product Introduction
The SP-YC71S tuning fork level switch is a vibration-based point level detector for liquids and free-flowing solids. Its 316L stainless steel fork is driven by piezoelectric crystals to generate vibrations, which are damped when contacting materials to trigger switching signals. The graded sensitivity design along the fork prevents false signals during material buildup or discharge processes. This compact device suits automated control in industries like chemical, power and cement plants.14
Key Features
With no moving parts, this maintenance-free switch offers long service life. Custom fork lengths from 128mm to 200mm are available, operating between -40℃ to 220℃. It supports both AC220V and DC24V power supply, with threaded or flanged process connections. The anti-coating fork structure works reliably with viscous liquids or adhesive materials, unaffected by conductivity or dielectric properties. Relay outputs provide direct control capability for industrial systems.17
Operating Principle
Piezoelectric elements excite the fork at resonant frequency, while smart electronics monitor vibration amplitude changes caused by material contact. The frequency gradient design ensures consistent detection performance even under challenging conditions like material buildup or temperature variations. This principle guarantees reliable switching without calibration requirements.116
Typical Applications
Ideal for coal bunkers in power plants, oil storage tanks and chemical reactors, this switch excels in hygienic applications like beer fermenters and paper glue tanks. It effectively monitors cement silos, wastewater treatment ponds and deep wells, with corrosion resistance against acids, alkalis and slurries. The robust construction withstands industrial environments with dust, moisture or temperature extremes.412
SP-YC71S料位開(kāi)關(guān)
阻旋料位開(kāi)關(guān)產(chǎn)品原理：阻旋料位開(kāi)關(guān)是一種用于固態(tài)物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器。其利用永磁電機(jī)帶動(dòng)葉片旋轉(zhuǎn)，當(dāng)被檢測(cè)物料上升至葉片位置時(shí)，葉片轉(zhuǎn)動(dòng)受阻，該阻力通過(guò)傳動(dòng)軸傳遞到接線盒內(nèi)的檢測(cè)裝置，檢測(cè)裝置則向外輸出一個(gè)開(kāi)關(guān)信號(hào)，并切斷電機(jī)電源使葉片停止轉(zhuǎn)動(dòng)。當(dāng)物料下降時(shí)，葉片阻力消失，檢測(cè)裝置便依靠彈簧的拉力恢復(fù)到原始狀態(tài)，葉片恢復(fù)旋轉(zhuǎn)狀態(tài)。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業(yè)得到了的應(yīng)用。
