DESCRIPTION

· Posifa designed the PMF5000 series of mass air flow sensors specifically for portable medical devices.

· The sensor is fast and accurate, enabling precise gas delivery in pulse mode.

· The sensor’s small footprint fits well in space-constrained housings.

· Push-to-connect fittings support efficient assembly.

· Flow direction (forward or backward) can be customized to fit existing system layouts.

· Features Posifa’s third-generation thermal flow die with advanced microfabrication innovations.

· Uses a pair of thermopiles to detect temperature gradient changes caused by mass flow, offering excellent signal-to-noise and repeatability.

· "Solid state" thermal isolation structure eliminates the need for surface cavities or fragile membranes, making it resistant to clogging and pressure shock.

· Includes analog output PMF5000V and digital I²C output PMF5000D.

· Proven in FAA approved, FDA cleared, and CE certified medical devices.

FEATURES

· Unsurpassed performance in a robust and cost-effective package.

· "Solid state" sensing core resistant to clogging and pressure shock.

· Highly accurate (4% reading typ.).

· Fast response time (5 ms typ.).

· Linear output and temperature compensation.

· Long-term stability with minimal null drift.

· Push-to-connect fittings.

· Flow direction can be customized (forward or backward).

· Analog or digital I2C output.

· Proven in FAA approved, FDA cleared, and CE certified medical devices.

APPLICATIONS
