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
