Airflow Sensors AWM700 Series, Compensated/Amplified

Airflow Sensors The AWM700 Series, Compensated/Amplified Airflow Sensors provide in-line flow measurement with a specially designed bypass flow housing. These sensors measure flow as high as 300 standard liters per minute (SLPM) while inducing a typical pressure drop of 1 inH2O. The AWM700 has a high flow range capability in a small package, as well as a 6 ms response time. These sensors require a 10 Vdc supply, but consume only 60 mW of power. The compact plastic package withstands overpressures of 1720 mbar | 172 kPa | 25 psi without compromising performance. The snap-in AMP-compatible...

AWM700 Series, Compensated/Amplified LAMINAR FLOW Due to the fast response time of the sensor, the specifications in this datasheet were generated using laminar flow. Airflow instability or “turbulence” present in the airstream will result in an increase in measurement uncertainty. Turbulent flow may be corrected by either of the following two methods: • Straightening the airflow by using flow laminarizing. • Slowing the response of the sensor by using a simple RC time constant on the output of the sensor. (This will slow down the sensor response time. The values needed depend on the amount...
