Pressure Sensor

PMF6000 was developed specifically for use in bypass assemblies by customers wishing to design their own flow body and restrictor element. By utilizing the linearized factory calibration from Posifa customers can create master calibration curves specific to their custom bypass design with minimal additional corrections in the production process. The compact packaging protects the flow die inside and provides a standardized package for manifold mounting.

PMF6000 features 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 excellent signal-to-noise, and repeatability. The “solid state” thermal isolation structure on the sensor die eliminates the need for surface cavity or fragile membrane used in competing technologies, making the sensor resistant to clogging and pressure shock.

The PMF6000 series includes the analog output PMF6000V and the digital I²C output PMF6000D
