KEY FEATURES

•

AC VOLTAGE RATING: 24.0 VOLTS NOMINAL

•

USAGE DESIGN: FIELD AND AIRCRAFT

•

DESIGN TYPE: NONTRIPOD MOUNTING

•

MEDIA DETECTED: ICE AND WATER

•

FUNCTIONAL DESCRIPTION: DETERMINE THE PRESENCE OF ICING CONDITIONS. ITS MAIN COMPONENT IS A NICKEL ALLOW ROD THAT HAS A NATURAL RESONANT FREQUENCY OF 40KHZ. AS ICE COLLECTS ON THE ROD,THE ADDED MASS CAUSE THE RESONANT FREQUENCY TO DECREASE. WHEN THE FREQUENCY DECREASES TO 130HZ(OR 0.02-IN LAYER OF ICE) AN INTERNAL HEATER AUTOMATICALLY DEFROSTS THE SENSOR. KHz
