双点超声波液位开关

Increasing demands for compliance with safety systems and overfill protection has mandated more reliable point level measurement. Echotel® Model 962 Ultrasonic Level Switches meet these demands with advanced transducer designs, extensive hazardous location approvals, and a new self-test technology.

Model 962 is a dual point switch that can be used as a level controller, or to control pumps in an auto fill or auto empty mode. The tip sensitive lower gap performs well in aerated or foamy liquids, and can measure to within 1.4" of the vessel bottom. The rigidity of the unique flow-through upper gap allows separations of up to 125" (318 cm) between the upper and lower transducer gaps.

 

Adjustable time delay for turbulent aerated liquids

Pulsed signal technology

Extensive FM, CSA and ATEX explosion proof and intrinsically safe approvals

Suitable for Safety Integrity Level (SIL) 2 loops
