Abstract
A measurement system for monitoring ambient temperature and airspeed is disclosed. The measurement system uses a single temperature sensor, disposed in the environment under test, in communication with a controller. The controller supplies a first current to the temperature sensor to measure the ambient temperature of the environment. This first current is selected so that it results in little or no self-heating of the temperature sensor. After the ambient temperature is determined, a second, higher current is applied to the temperature sensor. This higher current serves to heat the temperature sensor be a predetermined amount. Based on the expected temperature rise, the ambient temperature and the actual monitored temperature, the airspeed may be determined.
