Optic Leak Detection (Lo10 Series) - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

SENSOR INFORMATION (optic)
Optic Leak Detection Switch (LO10 Series): The Optic Leak Detector use principles of optical refraction to
detect the presence or absence of fluid. A pulsed infrared light beam is internally generated by a light
emitting diode and aimed at the slanted optical tip of the sensor. If the tip is dry, the light beam bounces at a
90 degree angle to a receiving photo transistor, indicating a dry condition. If the tip is immersed in liquid, the
light beam will refract out into the liquid instead of being reflected to the photo transistor, indicating a wet
condition.
The LO10 series is designed as a leak detection switch. The switch should be installed in applications
where under normal conditions, it remains away from the liquid and will only come into contact during a
leak.
The Optic Leak Detector cannot detect the presence or absence of specular application liquids that
reflect light (such as milk), or viscous liquids (such as paint) that form a coating on the sensor tip.
