Several key points have been discussed in this module and are summarized here. The Honeywell Zephyr™ Digital Airflow Sensor delivers a very accurate airflow reading (±2.5%), often ideal for demanding applications with high accuracy requirements. Device customization gives users the ability to design the sensor to meet their application needs. High sensitivity at low flows allows the customers application the ability to detect the presence or absence of airflow. High stability reduces errors due to thermal effects and null shift to provide accurate readings over time, often eliminating the need for system calibration after PCB mount and periodically over time. Low pressure drop typically improves patient comfort in medical applications, and reduces noise and system wear in components such as motors and pumps. Finally, linear output provides a more intuitive sensor signal than the raw output of basic airflow sensors, often eliminating the need for customers having to linearize the output which can help to reduce production and design costs and implementation time.
