DBLW-II料位開關
DBLW-II料位開關產品概述
DBLW-II阻旋式料位開關是一種用于固態物料（包括粉狀、粒狀、塊狀、膠狀等）的自動化檢測設備，適用于化工、塑料、水泥、醫藥、飼料、食品等行業。該產品采用不銹鋼材質葉片和密封設計，具有過載保護功能，能通過調整彈簧拉力適應不同比重的物料。其結構輕巧、安裝簡便，可水平、傾斜或垂直安裝，適用于工廠自動給料系統或生產線上的料位監測。135
技術特點與工作原理
該料位開關通過微型電機驅動葉片以2.5-3轉/分鐘的轉速旋轉，當物料觸及葉片時，傳動機構觸發微動開關輸出信號并切斷電機電源；物料下降后葉片自動復位恢復運轉。產品具備雙重保護機制：過載保護防止外力損壞電機，自動斷電功能延長設備壽命。其防塵密封性能可承受1MPa壓力，且不受物料粒度、濕度、溫度（-20℃~80℃）及粉塵濃度變化的影響。1922
應用場景與安裝建議
DBLW-II廣泛應用于粉煤灰倉、水泥倉、糧食倉儲等場景，特別適合導電性、粘濕性或高粉塵物料的檢測。安裝時需避開進料口和死料區，側裝時應使出線口垂直向下防雨水滲入，垂直安裝建議加裝防護套筒避免物料直接沖擊葉片。多位測量時需保持足夠間距防止軟軸纏繞。產品的小型化設計使其在空間受限的料斗中也能靈活部署。4514
DBLW-II Level Switch Product Overview
The DBLW-II rotary paddle level switch is designed for detecting solid materials (including powders, granules, lumps, and viscous substances) in industries such as chemical processing, plastics, cement, pharmaceuticals, feed, and food production. Featuring stainless steel blades and sealed construction, it incorporates overload protection and adjustable spring tension to accommodate materials with varying specific weights. Its compact and lightweight design allows flexible horizontal, inclined, or vertical installation in automated feeding systems or production lines.135
Technical Features & Operating Principle
Powered by a micro motor, the blade rotates at 2.5-3 RPM. Upon contacting materials, the mechanism triggers a microswitch to output signals while cutting off power. The self-resetting function reactivates rotation when material levels drop. Dual protection mechanisms include torque overload slip to safeguard the motor and automatic power-off during prolonged obstruction. With IP65-rated dustproof sealing and 1MPa pressure resistance, it maintains stable performance unaffected by material particle size, humidity, temperature (-20℃~80℃), or dust concentration.92228
Applications & Installation Guidelines
Ideal for silos storing fly ash, cement, or grains, this switch excels in conductive, adhesive, or high-dust environments. Installation should avoid material flow paths and dead zones. Side-mounting requires downward-facing cable outlets to prevent water ingress, while vertical installations benefit from protective sleeves. Maintain adequate spacing between multiple units to prevent shaft entanglement. The space-saving design suits confined hoppers and small-scale material handling systems.41427
DBLW-II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。
