Dwyer OLS are optical level switches. These low cost, compact instruments provide a transistor style switch output in the presence (or absence) of liquid. Technology is via IR light refraction in the presence of liquid. Dwyer OLS level switches have no moving parts and are available in a variety of wetted materials including 316SS, polysulfone and PFA. Local LEDs indicate the presence or absence of liquid along with transistor output. Compact switch can be quickly mounted horizontally or vertically for each installation (take care to avoid air bubbles etc on pipe installs).
Dwyer OLS switches are ideal for leak detection systems and are unaffected by liquid density. Coverage of the sensor is required to tigger, approx 5mm
