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
