Gems LS-52100 Series Single-Point Level Switch solve the problem of point level sensing in tanks with inaccessible tops or bottoms, or at intermediate locations in larger tanks. Installation is through the tank side at the detection point. Rugged, all stainless-steel unit offers broad chemical compatibility at temperatures to 300°F (149°C). Explosion-proof models are available.
Gems Sensors LS-52100 Series Level Switch
| Gems LS-2050 / LS-52100 Series Side Mount Level Switches Technical Specifications | |
|---|---|
| ● GENERAL | |
| Description | Side mounting float level switches for point level sensing in tanks with inaccessible tops or bottoms, or at intermediate locations in larger tanks. Installation is through the tank side at the detection point. |
| Operating Principle | The float pivots with changing liquid level, displacing a shuttle which magnetically actuates a hermetically sealed switch within the unit. |
| Product Variants | LS-2050 (Brass and Buna N): general purpose materials for reliable service in oils and water. LS-2050 (All-Stainless Steel): ultimate strength for pressures to 900 PSIG and temperatures to 300°F (148.9°C). LS-52100 (All-Stainless Steel): rugged, all-stainless steel unit offering broad chemical compatibility at temperatures to 300°F (148.9°C). |
