Electronic Dipstick

A real-world story of NASA technology finding a life beyond the mission.

About this technology

Overview

Lake-Tronic's Negative Thermistor Coefficients (NTC) prevent engine nozzles in the Space Shuttle Orbiter from swinging from side to side changing the thrust line. This technology has been adapted to an Electronik Dipstick, used to automatically monitor automotive fluid levels. NTC's are placed at predetermined levels in the dipstick and heated. Contact with fluids dissipates the heat creating a resistance change, which is analyzed by a microprocessor. Installation is simple, and additional applications are under consideration. *This product is no longer manufactured.
