Honeywell Zephyr™ HAF Series – High Accuracy ±50 SCCM to ±750 SCCM

Honeywell Zephyr™ HAF Series sensors provide a digital interface for monitoring airflow over specified full-scale flow and compensated temperature ranges. The thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow.

Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases. Standard flow ranges are available at ±50, ±100, ±200, ±400 or ±750 sccm. Custom flow ranges are also available. The sensors are fully calibrated and temperature compensated with an onboard Application Specific Integrated Circuit (ASIC).

The HAF Series is compensated over the temperature range of 0°C to 50°C and operates across a temperature range of -20°C to 70°C. The state-of-the-art ASIC-based compensation provides digital (I2C) outputs with a response time of 1 ms.

These sensors operate on the heat transfer principle to measure mass airflow. They consist of a microbridge Microelectronic and Microelectromechanical System (MEMS) with temperature-sensitive resistors deposited with thin films of platinum and silicon nitride. The MEMS sensing die is located in a precise and carefully designed airflow channel to provide repeatable response to flow.

Zephyr sensors provide the customer with enhanced reliability, high accuracy, repeatable measurements and the ability to customise sensor options to meet many specific application needs. The combination of rugged housings with a stable substrate makes these products robust. They are designed and manufactured according to ISO 9001 standards.

Honeywell Amplified Airflow Sensor, Dry Gas, 5V DC - HAF Series - HAFBLF0050CAAX5

Looking for a reliable high-response device for measuring the flow of air or other gas media? This amplified airflow sensor from Honeywell is designed with innovative Zephyr technology to provide highly accurate readings for mass flow of air and other non-corrosive gases. It's equipped with an advanced ASIC (application-specific integrated circuit) chip that produces a digital output at a response speed of 1ms. The sensor's compact nature means it takes up very little room on your PCB (printed circuit board), so you can use it in applications where space is limited. Its external housing is made from a high-quality polymer material that maintains resistance to chemicals and corrosion even under increased temperatures.

Features & Benefits

• Operating temperature range between -20°C and +70°C to cope with extreme conditions
• Low pressure drop reduces noise
• High stability improves overall performance and reduces errors from thermal effects
• Tubing connection style for easy integration

Applications

• HVAC (heating, ventilation, and air conditioning) filters
• Patient monitoring systems

How long can this digital airflow sensor last?

With regular maintenance, this airflow sensor will offer a long service life. The outer polymer material protects the component from damage from external sources, making it durable and suitable for use in harsh environments.
