Magnetrol 961-7DA0-0C0 Ultrasonic Level Switch Inquiry Item

Details

This Magnetrol 961-7DA0-0C0 belongs to Echotel 961 series ultrasonic point level switch. It adopts gap ultrasonic detection principle, judge whether the liquid fills the transducer gap to realize single-point level detection. It is two-wire loop powered design, normal state output 8mA, level alarm output 16mA, fault state can be set to 3.6mA or 22mA. Built-in self-diagnosis circuit, optional high/low fail-safe mode, time delay adjustable from 0.5s to 10s to avoid false triggering caused by liquid splashing. It is not affected by foam, viscosity, conductivity, suitable for oil, water and most chemical liquids. With SIL safety certification and explosion-proof approval, widely used in petrochemical, oil depot, water treatment tank high and low level alarm, pump protection interlock.
