Honeywell has expanded its Zephyr airflow sensor HAF Series portfolio with new digital versions that provide airflow ranges of 0 to 20 SLPM (Standard Liters per Minute) and 0 to 200 SLPM. With this new product, Honeywell 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.
"With this new extension to the Zephyr HAF Series, our customers can now choose between creating a separate bypass or using one included in the sensor," said Jacky Leff, senior product marketing manager for Honeywell Sensing and Control. "These sensors are configurable and customizable with multiple interface and package options, a variety of flow ranges, and custom calibration - all which increase the customer's options for integrating the sensor into the application."
According to the company, the new airflow sensors are designed to function in a 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.
When using the Zephyr building block, the customer needs to ensure that the air is laminarized when it enters the bypass, and does this through the use of the bypass shape, filters, screens, etc. With the new Zephyr airflow sensor, the sensor is directly in the main flow channel and the bypass is optimized inside the sensor.
