Abstract
The sensors and heater of a microbridge flow sensor are each compensated for non-linear curvature of the resistance versus temperature curve by the use of a section of permalloy in series with a section of platinum thin film resistor. The platinum exhibits non-linearity in one direction and the permalloy exhibits non-linearity in the opposite direction.
