14. c Switch The Ultrasonic level switch generates a 1 5 MHz ultrasonic wave from a miniature piezoelectric transducer located on one side of the gap in its sensing tip Another piezo transducer located on the other side of the gap acts as a microphone picking up the sound When liq uid enters the gap in the sensing tip the audio level changes The sensor should be installed so that the liquid will drip out of the gap when the sensor becomes dry Optic Switch The Optic Leak Detector use principles of optical refraction to detect the presence or absence of fluid A pulsed infrared light beam is inter nally 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 con dition If the tip is immersed in liquid the light beam will refract out into the liquid instead of being reflected to the photo transistor indi cating a wet condition The Optic Leak Detector can not 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 SuperGuard Capacitance Switch The SuperGuard level switch generates a pulse wave radio frequency signal from the capacitance electrode located in the sensing tip of each sensor When liquid comes into contact with the sensing tip the capacitance as measured by the
