# LIQUID LEVEL SENSOR ![Product image](https://novapart.co/image/farnell:3046710/) **URL**: https://novapart.co/products/30290/liquid-level-sensor **SKU**: 30290 **Manufacturer**: GEMS SENSORS **Category**: Sensors & Transducers || Sensors || Liquid Level Sensors || Float Liquid Level Sensors **Price**: €558.5800 **Stock**: 10+ ## Specifications | Parameter | Value | |---|---| | Product Range | LS-2050 Series | | Sensor Body Material | Stainless Steel | | Operating Pressure Max | 900psi | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3046710/) ## Large Size – Alloys Side Mounting Switches Solve the Problem of Inaccessible Tank Tops & Bottoms These units solve the problem of point level sensing in tanks with Typical Installation inaccessible tops or bottoms, or at intermediate locations in larger tanks. Operation is positive and dependable. The float pivots with changing liquid level, displacing a shuttle which magnetically actuates a hermetically sealed switch within the unit. Installation is through the tank side at the detection point. ~~a~~ l LS-2050 Series – Brass and Buna N LS-2050 Series – All-Stainless Steel ## LS-52100 Series – All Stainless Steel General purpose materials designed to provide reliable service in oils and water. Ultimate strength: for pressures to 900 PSIG and temperatures to 300°F (148.9°C). Explosion-proof models available. Rugged, all-stainless steel unit offers broad chemical compatibility at temperatures to 300°F (148.9°C). Explosion-proof models available.
