Ultrasonic level sensor HSA-70

HSA-70	Ultrasonic level sensor
	Compact body that is chemical resistance and corrosion proof RS-232C interface and current output with 4 to 20mA are provided

This sensor has applied "principle of echo" that sound reflects in a thing and comes on the contrary. It measures transmission time from projecting ultrasonic to receiving it and distance is measured.
It is possible to measure even if condensing on transmission surface.
It corresponds to chemical and corrosion-proof by united resin mold(polypropylene).
It is easy connection system with water-proof connector.
