SP-YC71S料位開關
產品概述
SP-YC71S音叉料位開關是一款基于振動原理設計的物位檢測儀表，適用于液體和自由流動固體粉料的界面測量。該產品采用316L不銹鋼材質叉體，通過壓電晶體驅動音叉振動并檢測頻率變化，當物料接觸叉體時振動受阻觸發開關信號，實現高精度點位檢測。其獨特設計確保物料堆積或排放時不會產生誤信號，適用于化工、電力、水泥等工業場景的自動化控制。14
技術特點
該料位開關采用無活動部件的機械結構，具有免維護、長壽命的特點。叉體長度支持128mm至200mm定制延長，工作溫度覆蓋-40℃至220℃范圍，提供AC220V或DC24V供電選項。過程連接支持螺紋和法蘭兩種方式，輸出為繼電器開關信號。產品特別設計防掛料結構，適用于粘稠液體或易附著物料的工況，且不受介質電導率、介電常數等參數影響。17
工作原理
SP-YC71S通過壓電晶片激勵音叉產生固定頻率振動，當物料接觸叉體時振動能量被吸收導致振幅衰減，內置智能電路檢測該變化并轉換為開關量輸出。共振頻率設計使探頭對物料接觸高度敏感，同時叉體前段至底座采用靈敏度梯度設計，有效避免物料堆積造成的誤觸發。該原理確保在復雜工況下仍能保持穩定檢測性能。116
應用領域
該產品廣泛應用于電廠煤倉、油田儲罐、化工反應器等場景的料位監測，特別適合啤酒發酵罐、造紙膠水儲倉等衛生要求較高的場合。在水泥行業可用于生料倉、煤粉倉的料位控制，水處理領域則適用于沉淀池、深井等液位報警。其防腐設計能耐受酸堿溶液、泥漿等腐蝕性介質。412
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料位開關
阻旋料位開關產品原理：阻旋料位開關是一種用于固態物料（包括粉狀、粒狀、塊狀、膠狀等）的物位控制器。其利用永磁電機帶動葉片旋轉，當被檢測物料上升至葉片位置時，葉片轉動受阻，該阻力通過傳動軸傳遞到接線盒內的檢測裝置，檢測裝置則向外輸出一個開關信號，并切斷電機電源使葉片停止轉動。當物料下降時，葉片阻力消失，檢測裝置便依靠彈簧的拉力恢復到原始狀態，葉片恢復旋轉狀態。在化工、塑料、鋼鐵、電力、水泥、制藥、飼料、食品等行業得到了的應用。
