This unamplified airflow sensor from Honeywell is a flow metre device that helps you measure dry gas in your system. It works as a microbridge where gas first flows into the small pipe and onto the microchip. The device then converts the flow rate into an electrical current reading before the gas flows out of the other end of the pipe and back into your system. It can measure a large flow rate of +200cm³/min (centimetres cubed per minute). The sensor continually reads the gas passing through it to provide you with accurate real-time readings.

• Maximum pressure of 25psi (pounds per square inch) for use in high-pressure systems
• Plastic body material for resistance to impact and wear
• Broad working temperature range of -25°C to +85°C for use in demanding environments
• Bidirectional sensing so the gas can enter the pipe from either side for a flexible set-up

• Heating, ventilation and air conditioning (HVAC) systems
• Gas analysers
• Medical respirators
• Leak detection

This sensor is installed using a through-hole termination method on a PCB (printed circuit board) for simple and secure mounting.
