Optical Liquid Level Sensors
Point level sensing for water and most liquids — no moving parts
Overview
Optical liquid level sensors use total internal reflection at a prism tip to detect the presence or absence of liquid — switching cleanly between air and liquid states with no moving parts. The OS Series offers six models ranging from basic to high-performance glass prism designs rated to 250 PSIG.
