* "Gage" models can also read differential pressure if High port pressure is greater than Low port pressure.
** Exceeding the Proof Pressure on any port causes permanent sensor failure.
P300 Sensors can be easily scaled by the user to read in any pressure unit (psi, kPa, bar, etc.); see calculator.
Differential models: Input range is + full scale pressure range to - full scale pressure range. For example: Pressure range for P300-10in-D is +10 inch H2O to -10 inch H2O. Differential models may also be used to read gage pressure by using the LOW port to sense ambient pressure.
Gage models: Input range is from 0 to full scale pressure range. Gage models may also be used to read differential pressure in applications where one side is always at a higher pressure. The higher pressure is connected to the Pressure port, and the lower pressure is connected to the REF (reference) port.
