核心功能与技术特点
PRL-170采用全机械结构设计，主轴三重密封有效防止粉尘侵入，抗振动和抗冲击性能优异。标准配置的SUS304不锈钢叶片（80×80mm）与铝合金外壳组合，可在0-196kPa压力范围内稳定工作，最高耐受温度达70℃。产品提供AC100/110V或AC200/220V电源版本，消耗功率仅2.5W，输出1C接点信号（250VAC/6A）。独特的设计使其能够克服物料挂壁问题，即使被测物料特性发生轻微变化也不会产生误动作。安装方式支持M30P2螺纹或定制法兰连接，防护等级达到IP65。3714
产品系列与定制服务
作为东和制电PRL系列的主力型号，PRL-170可与同系列40余种规格产品形成完整解决方案。用户可根据实际需求选择不同长度的延长杆（标准杆长175mm）或护套，高温环境可选PRL-200型（耐400℃）。针对特殊安装条件，厂商提供伸缩轴（PRL-100EB型）、双法兰（PRL-100F型）等变型设计。所有型号均支持非标定制，包括叶片尺寸、输出信号类型等参数的个性化调整，但需注意变更叶片规格时会影响检测位置。132123
应用场景与使用建议
该产品特别适合粉煤灰、谷物、塑料颗粒等干燥粉粒状物料的位面检测。在实际应用中，建议避开物料死角区域安装，并注意安息角对检测精度的影响。对于存在轻微振动的场合，可通过加装缓冲支架确保稳定性。当物料流动性差异较大时，推荐通过更换W系列（宽叶片）或S系列（窄叶片）来优化检测效果。维护时仅需定期检查主轴密封状况，无需专业工具即可完成叶片更换。61626
PRL-170 Rotary Paddle Level Switch Overview
The PRL-170 is a mechanically-operated point level indicator manufactured by TOWA SEIDEN of Japan, designed for reliable detection of powdered or granular materials in industrial storage and processing systems. Its working principle relies on the resistance torque generated when the rotating paddle encounters material, triggering a switch action without requiring sensitivity adjustment. The device is widely implemented in power plants, cement factories, food processing facilities and chemical plants due to its consistent performance across varying material densities. Standard models support both 100V/110V and 200V/220V AC power supply with low 2.5W consumption. 2918
Mechanical Design Features
Constructed with durable aluminum alloy housing and SUS304 stainless steel paddle (80×80mm standard size), the PRL-170 demonstrates exceptional resistance to material buildup and mechanical stress. The triple-sealed rotating shaft effectively prevents dust ingress, while the IP65 enclosure protects internal components from environmental factors. Operating parameters include 0-196kPa pressure range and ambient temperature up to 55℃ (material temperature 70℃ max). The 1C contact output (250VAC/6A resistive load) ensures compatibility with most control systems. Unique slip mechanism safeguards the motor from overload damage during accidental paddle impacts. 111722
Configuration Flexibility
This switch belongs to TOWA s comprehensive PRL series comprising over 40 models for diverse applications. The standard 175mm insertion length can be customized, with optional extensions or protective sleeves available. For high-temperature processes up to 400℃, the PRL-200 variant is recommended. Special versions include retractable shaft (PRL-100EB) for vertical mounting and double-flange (PRL-100F) designs. Customers may request paddle size modifications (e.g., 30×60mm for PRL-500N model) though such changes may affect detection point positioning and require engineering evaluation. 81524
Operational Guidelines
Ideal for monitoring free-flowing dry materials like fly ash or plastic pellets, the PRL-170 should be installed avoiding material dead zones and bridging areas. When handling materials with significantly different bulk densities, selecting appropriate paddle sizes (W-series for lightweight or S-series for heavy materials) optimizes detection reliability. In vibrating environments, supplementary mounting brackets are advised. Maintenance involves periodic inspection of shaft seals and paddle condition, with tool-free replacement procedure for worn components. The mechanical design ensures long service life with minimal downtime. 51019
