The different temperature behaviour of fluidic form and laminar resistors can be used to construct pressure divider circuits with temperature dependent output pressure. The temperature sensitivities of four pressure dividers can be compared by using a graphical method. The influence of supply pressure fluctuations can be reduced essentially if two pressure dividers are combined to a DC bridge circuit.
