PMFc700 SERIES
MASS AIR FLOW SENSORS
DESCRIPTION
Posifa鈥檚 PMFc700 series of Mass Air FlowSensors offer pin compatible upgrade
solutions to the popular AWM700 series fromHoneywell. Using the robust Posifa ThermalFlow Sensor Die, and incorporating the latest microcontroller technology, PMFc700 offers drastically improved interchangeability (<2% full scale), temperature stability (<3% full scale from 0掳C to +50掳C), and resistance to adverse environmental factors such as dust particles and water vapor that have plaqued the AWM700.
Tailored to meet the exacting packaging and calibration specifications of AWM700, PMFc700 also offers enhanced interchangeability by improving the output tolerance by over 200% to<2% full scale. Additionally, PMFc700 is temperature compensated to <3% full scale drift over the temperature range of 0掳C to +50掳C. For those more stringent applications, Posifa offers other precision versions with output tolerance as low as 1.5%.
Posifa designed the PMFc700 series of Mass Air Flow Sensors from the ground up, incorporating the latest MEMS and microelectronics innovations. The sensor die uses a pair of thermopiles to detect changes in temperature gradient caused by mass flow, delivering ultra-low noise to signal, and unsurpassed repeatability. The 鈥渟olid state鈥� thermal ***lation on the die eliminates the need for surface cavity or fragile membrane, making the sensor resistant to clogging (from water vapor or dust particles) and pressure shock. The sensor鈥檚 signal conditioning circuitry leverages off-the-shelf microcontroller, providing proven reliability and low cost.
Applications in medical, industrial and
transportation industries are benefiting by:
Taking advantage of tighter tolerances
Eliminating complicated and expensive
temperature compensation schemes
Inherent immunity to adverse environmental
factors
