Flow sensor PMF86000

for respiratory devicesfor anesthesia equipmentmonitoring

PMF86000 is Posifa Technologies’ nextgeneration of mass air flow sensors for respiratory care and other medical and instrumentation applications. Compared to our previous generation solution, the PMF86000 Series offers improved accuracy, repeatability, and signal-to-noise performance. The PMF86000 series features Posifa’s thirdgeneration thermal flow die, benefiting from the latest innovations in microfabrication. The entire sensor PCB assembly is coated with parylene, including the sensor die, allowing the sensor to perform reliabily in harsh environments such as high humidity and trace amount of corrosive gases. The PMF86000 series has adopted a single, main flow path design, eliminating the risk of bypass being clogged by water condesation and dust particles. The PMF88000 sensors provide both analog (voltage) and digital I2C outputs, and support bi-directional flow measurement. APPLICATIONS • Oxygen concentrators • Respirators and ventilators • Nebulizers • CPAP equipment • Anesthesia delivery • Environmental monitoring • Fuel cell control FEATURES • Accurate and low noise • Fast response time • Resistant to condensed water and dust particles • Long-term stability • Bidirectional flow sensing (optional) • Analog and I2C, Linear output MAXIMUM RATINGS • Operating Temperature: -25°C to 85°C • Compensated Temperature: 0°C to 50°C • Storage Temperature: -40°C to 90°C
