What is the max pressure range on the MPXV7002DP differential pressure sensor? I see that on the datasheet, it says Pmax = 75 kPa. Does this mean the ABSOLUTE pressure on each port, or is this the maximum DIFFERENCE between P1 and P2? Similarly, is the measurement range of -0.3 to +0.3 PSI absolute or differential? I intend to use this to measure airspeed, so the absolute pressure on these ports will be around atmospheric pressure (14.7 PSI) and the difference in pressure from one to the other should be no more than 0.3 PSI. Does this work? Thanks!

Hello Theo,

Thank you very much for writing.

The MPXV7002DP is a

differential pressure sensor, which means that the difference in pressure between two points is measured where pressure is applied to both sides (Port P1 and Port P2) of sensor.In this case the pressure range is from -2kPa to 2kPa. This means that the device will respond to a difference in pressure from the range mentioned.

The maximum pressure that the device can support

before getting damagedis 75kPa.I hope this information helps.

Best Regards,

David
