Technical Overview
The TF-250-4-T2-550 level switch is a robust industrial device engineered for monitoring solid materials including powders, granules, and viscous substances. Its rotating paddle mechanism interacts physically with materials - when contacted, the paddle stops rotating and activates a microswitch, while spring-driven reset occurs upon material retreat. Featuring a motor protection system with automatic clutch disengagement, the device prevents damage from overload conditions. The hermetically sealed housing with IP65 rating ensures reliable operation in dusty or outdoor environments, and special paddle designs accommodate low-density materials. 617
結(jié)構(gòu)特點(diǎn)

Performance Features
With adjustable torque settings ranging from 5-25N·m, the switch adapts to materials of varying densities. The stainless steel shaft and bearings provide corrosion resistance, while the dual-seal construction maintains performance in temperatures up to 149°C (standard model) or 399°C (high-temperature version). The 10A/250VAC SPDT contact configuration offers flexible connectivity. Its vibration-resistant design ensures stable operation even in high-vibration environments like pneumatic conveying systems. The compact structure allows installation in limited spaces without compromising detection accuracy. 61724
應(yīng)用領(lǐng)域
該設(shè)備適用于多種工業(yè)場(chǎng)景的料位控制，包括鋼鐵廠原料倉(cāng)的滿空監(jiān)測(cè)、水泥廠生料庫(kù)的料位報(bào)警、飼料生產(chǎn)線中的配料控制等。在食品行業(yè)可用于面粉、糖粉等輕質(zhì)物料的檢測(cè)，在制藥領(lǐng)域能可靠監(jiān)測(cè)顆粒狀原料。產(chǎn)品對(duì)物料特性變化不敏感，不受介質(zhì)更換、壓力變化或輕微掛料影響，在復(fù)雜工況下仍能保持檢測(cè)一致性。1227
Application Scenarios
Ideal for bulk material handling systems, this level switch performs reliably in coal bunkers, grain silos, and plastic pellet hoppers. It effectively monitors fly ash in power plants, powdered chemicals in processing vessels, and aggregates in concrete mixing plants. The device s broad compatibility covers materials with densities from 80kg/m³ to 2000kg/m³. Its fail-safe design makes it suitable for critical applications like explosive material storage where false signals must be avoided. The product has proven effective in both light-duty packaging lines and heavy-duty mining operations. 62324
