AS40 features ACT’s third-generation thermal flow die, benefiting from the latest innovations in microfabrication. The sensor die uses a pair of thermopiles to detect changes in temperature gradient caused by mass flow, delivering excellentsignal-to-noise and repeatability. The “solid state” thermal isolation structure on the sensor die eliminates the need for surface cavity or fragile membrane used in competing technologies, making the sensor resistant to clogging and pressure shock.
The AS40 series includes the analog output AS40V and the digital I²C output AS40D.
The supported max flow rates range from 12 SLM to 300 SLM. The sensors are temperature compensated over the temperature range of 0 to 50 °C. The linearized output provides maximum flexibility and ease-of-use.MAXIMUM RATINGS
