HAFUHH0100L4AXT

HAFUHH0100L4AXT is a HAF series Zephyr™ digital airflow sensor. It provides a digital interface for reading airflow over specified full-scale flow and compensated temperature ranges. The thermally isolated heater and temperature sensing elements help this sensor provide a fast response to air or gas flow. Zephyr sensor is designed to measure mass flow of air and other non-corrosive gases. The sensor is fully calibrated and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC). The state of-the-art ASIC-based compensation provides digital (I2C) outputs with a response time of 1ms. Potential application includes anaesthesia delivery machines, ventilators, ventricular assist devices (heart pumps), spirometers, laparoscopy (medical), analytic instrumentation (spectrometry, chromatography), air-to-fuel ratio, fuel cells, fume hoods, gas leak detection, process control gas monitoring, vacuum pump monitoring (industrial).
