Switch-Tek™ LU10 Ultrasonic Level Switch
Application
CSA approved for hazardous environments, the intrinsically safe ultrasonic point level switch provides reliable liquid level detection of chemical, solvent, hydrocarbon and petroleum based liquids with a 1A relay output. Media examples include fuel, acetone and hydrochloric acid. The submersible polypropylene or PFA liquid level sensor is universally mounted through the tank wall or inside the tank as a high level alarm or low level alarm.
Features
 CSA approved intrinsically safe for use in hazardous environments
Submersible polypropylene or PFA Teflon® sensor and cable for corrosive liquids
60VA relay selectable NO or NC via power supply wiring polarity
Compatible with Smart Trak and Switch-Pak installation fittings
