LA20 Alphasonic Data Sheet 00
RICOCHET BULK TANK ALPHASONIC LEVEL TRANSMITTER • Accurate and reliable level measurement from 0.5 (.15) to 12 feet (3.7 meters) A high frequency ultrasonic sound wave is pulsed three times per second from the base of the transducer. The sound wave reflects against the process medium below and returns to the transducer. The microprocessor based electronics measure the time of flight between the sound generation and receipt, and translates this figure into the distance between the transmitter and process medium below. • Low-cost solution for OEM and process applications • Compact size and 2” transducer for small tanks • PP enclosure rated NEMA 4X with PVDF transducer • Echo-safe™ filtration eliminates false echo signal returns • Fail-safe intelligence provides maximum process safety General Purpose Yes Conductive Yes Non-conductive Yes ∆ Conductive Yes Non-contact Yes Clean Yes Dirty Yes Coating Yes Non-coating Yes Ambient pressureYes Low pressure Yes Medium pressure No Intrinsically safe No Integral relay No Foam No Contact No Vapors No ∆ Gas density No Vacuum No APPLICATION The two-wire, bulk tank alphasonic level transmitter is mounted through the top wall of the tank and provides non-contact measurement up to 12’. With non-contact technology, the transmitter is an excellent choice for applications with dirty, coating, corrosive type liquids. The compact design is the perfect size for small tank applications.

Relay Control Accessories For remote relay control and indication, package your level transmitter with the LC52-1001 continuous relay controller. The spanable controller features up to three process set points with two relay outputs and an isolated 4-20 mA repeater. Continuous Relay Controller LC52-1001 For multi-tank relay control and telemetry, complete your level package with the LC55-1001 LeveLink controller. The controller will automate up to eight tanks with 8 transmitter inputs and eight level switch inputs and eight relay output channels.
