Original Press Release:
Honeywell ZEPHYR(TM) Digital Airflow Sensors Deliver the Industry's Most Accurate Airflow Reading Across the Operating Range of the Sensor
Customizable Devices Provide High Sensitivity at Very Low Flows, Low Pressure Drop, High Stability, and Help Reduce Production Costs
MINNEAPOLIS - Honeywell (NYSE: HON) today announced the introduction of the Honeywell Zephyr(TM) Digital Airflow Sensors that deliver the industry's most accurate airflow reading across the operating range of the sensor. The new HAF Series devices provide highly accurate digital output, enhanced reliability, and repeatable measurements to meet many medical and industrial application specifications.
The Honeywell Zephyr(TM) Digital Airflow Sensors offer several competitive advantages not found in other digital airflow sensors, including:
The Honeywell Zephyr(TM) Digital Airflow Sensors simplify the customer's production requirements due to Application Specific Integrated Circuit (ASIC)-based I2 C digital output that eases integration to micro-processors or micro-controllers, reducing PCB complexity and component count. Their small size occupies less space on the PCB, allowing for a smaller PCB, which can reduce production costs and simplify installation in space-restricted applications. Their low 3.3 Vdc voltage option and low power supply requirements allow for use in battery-powered and portable applications.
Honeywell Zephyr(TM) Digital Airflow Sensors are designed to measure mass flow of air and other non-corrosive gases. They are available in standard flow ranges, and are fully calibrated and temperature compensated. They provide a digital interface for reading airflow over the specified full scale flow span and temperature range, and their thermally isolated heater and temperature sensing elements help provide a fast response to air or gas flow.
Potential medical applications include anesthesia delivery machines, hospital diagnostics (spectrometry, gas chromatography), nebulizers, oxygen concentrators, patient monitoring systems (respiratory monitoring), sleep apnea machines, spirometers, ventilators, and ventricular assist devices. Potential industrial applications include air-to-fuel ratio, analytical instrumentation (spectrometry, chromatography), fuel cells, gas leak detection, gas meters, HVAC filters, meteorology equipment, and variable air volume (VAV) systems on HVAC systems.
