Mass air flow sensor

摘要

Air mass flow sensor for use in a compact sensor module, links together two temperature sensors (6,7) with two heat element sensors (4,5), that are arranged adjacent to a measurement element with the temperature and heat sensors connected to two independent bridge circuits (I, II), with the bridge resistances (R2, R5, R12, R15) integral to the sensor module together with a microprocessor (16). The microprocessor is used to improve measurement accuracy by use of known data for adjustment purposes. Independent claims are made for a process for adjustment of an air mass sensor and signal analysis for an air mass sensor.
