Which sensor measure the pressure relative to atmospheric pressure?(a) Absolute pressure sensor(b) Gauge pressure sensor(c) Vacuum pressure sensor(d) Differential pressure sensorThe question was asked in my homework.This interesting question is from Pressure Sensor topic in chapter Sensors of IOT

Answer»

The CORRECT choice is (b) Gauge pressure SENSOR

For explanation I WOULD say: This sensor measures the pressure RELATIVE to atmospheric pressure. A TIRE pressure gauge is an example of gauge pressure measurement; when it indicates zero, then the pressure it is measuring is the same as the ambient pressure.
