Differential Pressure Sensor Specifications.
This Pressure sensor is capable of sensing up to 33.9 inches of mercury (Hg), or -115 Kilopascals (KPa). The PSI range of this sensor (relative to atmosphere) is -16.7 to +2.2 PSI (Pounds per Square Inch).
The voltage range for the range PSI or KPa is .2 volts at the -16.7 PSI and -115 KPa level and 4.6 volts at the 0 KPa or +2.2 PSI level.
The range of voltage that the sensor can receive (power rating) is 5v and a + or - range of .25 volts. So the pressure sensor can only accept voltages between 4.75v to 5.25v.
