Posifa Technologies Introduces Next-Generation Air Flow Sensors
April 26, 2021
News
Posifa Technologies announced the next generation of its mass air flow sensors for use in respiratory care and other medical and instrumentation applications.
The PMF83000 and PMF86000 series sensors are designed to provide protection and reliable performance in harsh environments with high humidity and trace amounts of corrosive gases. The new sensors have been enhanced with a parylene coating over the entire PCB assembly, including the sensor die.
Featuring robust packages, the sensors introduced serve as key components in ventilators, respirators, oxygen concentrators, nebulizers, and CPAP equipment, where they control the volume of air flow to patients. In addition, the devices provide mass flow measurement in anesthesia delivery, fuel cell control, and environmental monitoring equipment.
The PMF83000 and PMF86000 series feature Posifa'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 signal-to-noise performance and repeatability of 0.5 % F.S. Both series feature a single main flow path design, eliminating the risk of the bypass being clogged by water condensation and dust particles.
Measuring flow rates from 15 SLM to 100 SLM and 50 SLM to 300 SLM, respectively, the PMF83000 and PMF86000 series offer ideal response times of 5 ms typical and operate over temperature ranges of -25 °C to +65 °C. The devices provide both analog (voltage) and digital I²C outputs in the same package and support bidirectional flow measurement. Buyers should contact Posifa to discuss options for customizing the sensors' features and specifications.
Samples and production quantities of the PMF83000 and PMF86000 mass air flow sensors are available now.
