Airflow Sensors AWM700 Series, Compensated/Amplified Datasheet

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 inH O. 2 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 connector provides reliable connection. The AWM700 Series provides a combination of time-proven reliability, high accuracy, and precision operating characteristics. This inherent accuracy over life reduces need for recalibration. AWM700 sensor circuitry performs amplification and temperature compensation. The AWM720P1 and AWM730B5 were developed primarily for the medical ventilation market and meet the high performance requirements of many medical and analytical instrumentation applications.

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 of turbulence present in the application. A technique for laminarizing the flow includes adding the following separately-purchased laminar flow elements to the flow stream: • Hex-shaped honeycombs • Foam • Screen materials • Constrictors (frits) Unfortunately, the greater the efficiency of the laminarizer, the greater the increase in pressure drop in order to establish a given flow rate. Plastic honeycomb material probably gives the most improvement for the least pressure drop. Ensure sharp radii are avoided in any test fixture.
