SDR-11B料位开关
SDR-11B料位开关产品介绍(中文)
SDR-11B静电容料位开关是一种基于电容感应原理设计的物位检测设备,适用于各类粉状、粒状、块状及液体物料的料位监测。该产品通过感应棒与桶壁之间的电容量变化实现检测,当物料覆盖感应棒时电容值逐渐增加,达到预设阈值后触发开关信号输出。其无机械传动结构的设计显著延长了使用寿命,可适应-20℃至200℃的工作温度环境(特殊型号可达800℃),并具备0-60秒可调的动作延时功能。产品支持110V/220VAC或24VDC电源输入,提供NPN晶体管及5A/250VAC SPDT继电器两种输出方式,接线盒防护等级为IP-65,确保在粉尘、潮湿等复杂工业环境中稳定运行。SDR-11B广泛应用于水泥、化工、食品、制药等行业,特别适合高温、腐蚀性或多粉尘工况下的料位控制与报警。1712
Product Introduction of SDR-11B Level Switch (English)
The SDR-11B capacitive level switch is a non-contact detection device operating on the principle of capacitance sensing, designed for monitoring solid and liquid materials including powders, granules, and bulk solids. It detects level changes by measuring the capacitance variation between the sensing rod and vessel wall, triggering a switch signal when the material coverage reaches preset thresholds. With no moving mechanical parts, this device ensures long-term reliability and maintenance-free operation in harsh environments ranging from -20℃ to 200℃ (extendable to 800℃ for special versions). Featuring adjustable delay response (0-60 seconds) and dual output options (NPN transistor or 5A/250VAC SPDT relay), it accommodates 110V/220VAC or 24VDC power supply. The IP-65 rated enclosure provides robust protection against dust and moisture infiltration. Typical applications include process control in cement production, chemical processing, food storage, and pharmaceutical manufacturing, particularly where high temperature, corrosive media, or dusty conditions exist. 1716
技术特点与优势(中英文对照)
该产品采用全封闭式结构(Fully sealed design),独特的绝缘材质如SUS304外覆PP/PVDF(SUS304 with PP/PVDF coating)可防止介质粘附,实现自清洁功能(Self-cleaning capability)。其灵敏度可通过内部电位器自由调节(Adjustable sensitivity via internal potentiometers),适应不同介电常数的物料(Compatible with materials of varied dielectric constants)。双管谐振设计(Dual-tube resonance technology)增强了信号稳定性,避免了传统电容式开关易受物料特性影响的缺点。安装方式灵活,支持1"NPT螺纹或法兰连接(1"NPT threaded or flanged connection),适用于侧装、顶装等多种工况(Suitable for side/top mounting configurations)。71621
Application Scenarios
在电力行业(Power generation),用于煤仓料位监测(Coal bunker level monitoring);在食品加工(Food processing)中检测面粉、糖粉等轻质物料(Light-density materials like flour and powdered sugar);在化工领域(Chemical industry)实现酸碱性物料的可靠检测(Reliable detection of corrosive chemicals)。其防爆设计版本(Explosion-proof variants)可安全应用于易燃易爆环境(Hazardous areas with combustible dust)。产品通过模块化设计(Modular design)简化维护流程,用户可快速更换感应棒(Quick-replace sensing rod)而不影响主体结构。1712
SDR-11B料位开关
阻旋料位开关产品原理:阻旋料位开关是一种用于固态物料(包括粉状、粒状、块状、胶状等)的物位控制器。其利用永磁电机带动叶片旋转,当被检测物料上升至叶片位置时,叶片转动受阻,该阻力通过传动轴传递到接线盒内的检测装置,检测装置则向外输出一个开关信号,并切断电机电源使叶片停止转动。当物料下降时,叶片阻力消失,检测装置便依靠弹簧的拉力恢复到原始状态,叶片恢复旋转状态。在化工、塑料、钢铁、电力、水泥、制药、饲料、食品等行业得到了的应用。
