Question:

Has anyone studied SMC's PF2A7 □ □ H series digital flow switch, sensor and its drive circuit is what?

Has anyone studied SMC's PF2A7 □ □ H series digital flow switch, sensor and its drive circuit is what?

Answer:

PFM works by the internal MEMS chip in the work, MEMS chip has a thermistor can be heated to produce a certain amount of heat to be blown when the air can be detected within the heat offset, by determining the degree of heat to calculate the degree of deviation Its through the flow, the accuracy has been very high.

On the circuit you say I do not understand what the meaning of the internal no circuit, only a MEMS chip. Wiring diagram can have.
