Dayton, O. - With several model selections and a deadband of 38.1 mm (1.5-in.), the Superprox series of 18 mm, ultrasonic sensors offers short-range sensing solutions for specific dual-level control applications where mounting space is limited. The sensors monitor and control most non-hazardous liquid or dry material levels within sensing ranges up to 305 mm (12-in.). They can be configured for either a specific On/Off latch control function or a dual-alarm sensing function. Model selections include near and far limit parameters, alarm limits, output types including response to loss-of-echo conditions, and one of three operating functions: pump in, pump out, or dual alarm. Barrel-style threaded housings are available in either Ultem plastic or SS303 stainless steel.
