02-04-2020 | Posifa Technologies | Test & Measurement

Posifa Technologies continues to ship production quantities of its mass air flow sensors. These devices are a key component for ventilators and additional medical equipment. The Posifa PMF2000 and PMF4000 mass air flow sensors are employed within medical ventilators, controlling airflow to patients.


"We are making this announcement to proactively reassure our medical customers who have begun to ask for confirmation that production and delivery of our mass air flow sensors is continuing as normal," said Peng Tu, president and CEO of Posifa Technologies. "With our PMF2000 and PMF4000 manufacturing based in Taiwan, we are happy to confirm that production of these vital components is proceeding without any interruption and with normal lead times for delivery."


Solid-state MEMS air flow sensors from the company remove the requirement for a surface cavity or fragile membrane on the sensor die, making the sensor resistant to pressure shock and clogging from water condensation or dust particles while giving excellent accuracy and repeatability. Proven in an extensive assortment of applications from industrial use to FDA-approved medical equipment, the platforms they are based on allowing the company to provide a variety of flow ranges, output options, and mechanical interfaces to satisfy new and existing customer architectures.
