A system and method for pressure measurement may include the ability to readily produce a pressure measurement system. In one general aspect, pressure measurement 100 may include a signal-converting circuit 500 that includes a coupler 510, a signal biaser 550, and a signal span adjuster 560. The coupler is operable to receive a pressure-representative signal, and the signal biaser includes a thermally-insensitive voltage divider that facilitates biasing the pressure-representative signal. The signal span adjuster is coupled to the coupler and the signal biaser and includes a thermally-insensitive voltage divider that facilitates adjusting the span of the pressure-representative signal.
L'invention porte sur un système et un procédé de mesure de la pression qui permettent la production rapide et aisée d'un système de mesure de la pression. Selon un aspect général, le système de mesure de la pression de l'invention (100) peut comprendre un circuit de conversion de signal (500) comportant un coupleur (510), un dispositif de polarisation de signal (550) et un dispositif de réglage de la portée du signal (560). Le coupleur sert à recevoir un signal représentatif de la pression et le dispositif de polarisation de signal comprend un diviseur de tension non sensible à la température qui facilite la polarisation du signal représentatif de la pression. Le dispositif de réglage de la portée du signal est couplé au coupleur et au dispositif de polarisation du signal et comprend un diviseur de tension non sensible à la température qui facilite le réglage de la portée du signal représentatif de la pression.
