Mass Flow Sensors

PMF4000 Series Mass Air Flow Sensor

The PMF4000 Series of mass air flow sensors covers the ranges from 50 SLM to 300 SLM. The sensors are full calibrated and compensated over the temperature range of 0°C to 50°C. The linearized analog output of 1-5V provides maximum flexibility and ease-of-use. Like other PMF mass flow sensors, the PMF4000 incorporates the latest MEMs and microelectronics innovations.
