The new AWM90000 offers OEMs a wider range of mass flow sensor applications, due to its much improved price/performance ratio, low power consumption and an an extremely low pressure drop.

The new AWM90000 offers OEMs a wider range of mass flow sensor applications, due to its much improved price/performance ratio. There are two AWM90000 mass flow sensor available: the +/- 200 sccm version has an extremely low pressure drop of only 0.49 mbar while the +/- 5 mbar version offers low differential pressure measurement capabilities. The very low power consumption of both versions makes the sensor eligible for battery-powered applications.

Demanding measurements can take advantage of extremely low hysteresis and repeatability error, and highly stable null and full-scale outputs.

Both its low price and the small package size allow OEMs to incorporate mass flow sensors for the first time into their application.

The AWM90000 sensors are well suited for medical applications like CPAP equipment, sleep apnea monitors, oxygen conservers and concentrators, respirators, ventilators, spirometers and anaesthesia delivery.

Industrial applications include filter control systems, fuel to air ratio sensing and spectroscopy equipment.

Important features of the new mass flow sensors AWM9000 are: Flow range of +/- 200 sccm with a pressure drop of only 0.49 mbar; Differential pressure version ranging +/- 5 mbar; Response time of only 1 ms typical; Low power consumption of 50 mW max; Very compact package design (only 30 x 28 x 13 mm); Hysteresis and repeatability error less than 0.35 percent of reading.

The new flow sensor AWM90000 from Sensortechnics opens up a new range of applications for mass flow sensors.
