Honeywell has expanded its Zephyr airflow sensor HAF Series portfolio with new digital versions that provide airflow ranges of 0 to 20 Standard Liters per Minute (SLPM) and 0 to 200 SLPM. To accomplish this, it has leveraged its original Zephyr building block airflow sensor via a bypass to the main flow channel of the sensor, eliminating the need for a customer-designed bypass in equipment such as ventilators.

  Honeywell’s new Zephyr airflow sensors with the built-in bypass offer customers three important benefits. High performance includes a narrow total error band of ±4% reading and a high accuracy of ±3.5% reading, allowing for very precise airflow measurement—often ideal for demanding applications with high accuracy requirements. Ease of integration is provided thanks to simple electrical interfaces and multiple mechanical configurations—manifold mount, male and female fittings. And finally, custom calibration includes forward flow direction and optimized custom calibration for many gases (dry air, helium, argon, nitrogen, nitrous oxide, carbon dioxide), which eliminates the need to implement gas correction factors.

These new sensors are designed to function in a wide range of applications. Potential medical applications include anesthesia delivery machines, laparoscopy, patient monitoring systems, spirometers, ventilators and ventricular assist devices (heart pumps). Potential industrial applications include air-to-fuel ratio, analytical instrumentation, fuel cells, fume hoods, gas leak detection and gas meters.
