Industrial Point Level Switches
The Ultimate Selection Guide for Liquid & Solid Level Detection [cite: 602, 603]
📌 Overview
Point Level Switches are essential safety components used to detect a specific liquid or solid level to prevent overflows, dry-running of pumps, or material shortages[cite: 604]. Our range covers scenarios from simple water tanks to viscous slurries and heavy-dust silos[cite: 605].
📊 Quick Selection Matrix
| Product Series | Model(s) | Best Application [cite: 607] |
|---|---|---|
| Magnetic Float | UQK-01/02/03 | Marine, pump stations, industrial oil tanks |
| Vibrating Tuning Fork | UYC-10/20 | Food & Beverage, Pharmaceuticals, Water Treatment |
| Rotary Paddle | UZX-10 | Grain silos, cement tanks, hopper bins |
| RF Admittance | UMF/K | Asphalt, heavy oil, concentrated slurry |
| Multi-Point Float | UQK-L Series | Chemical storage, pump automation |
| Vibrating Rod | UDB Series | Powders, grains, clog-prone large particles |
🔍 Detailed Product Profiles
