Sensirion SFC5500 Digital Multi-Gas Mass Flow Controllers Now Shipping from Mouser

July 6, 2021 - Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking SFC5500 digital multi-gas mass flow controllers from Sensirion.

Sensirion SFC5500 controllers are CMOSens®-based devices that measure gas mass flow by the calorimetric principle based on heat transfer. The controllers achieve unmatched ratings for speed, accuracy, and repeatability at a very attractive system cost. A heater element on a thermally insulated membrane and two thermopiles located upstream and downstream are integrated on a single silicon chip. In the presence of gas flow, the temperature distribution up and downstream is disturbed. This asymmetry is then measured. A larger channel design makes the device more robust against particles, clogging, and humidified gases. Due to the compact single-chip design and mounting between metal parts, CMOSens-based sensors are also very resistant to electromagnetic disturbances (EMC).

Applications for the controllers include analytical instruments, bioreactors, medical equipment, process control, and industrial automation.
