PMF4000 (50 slm to 300 slm)

The PMF4000 series of Mass Air Flow Sensors covers the ranges from 50 SLM to 300 SLM. The sensors are fully calibrated and compensated over the temperature range of 0 to 50 °C (32 to 122 °F). The linearized analog output (1 to 5 V) provides maximum flexibility and ease-of-use.
