*Exceeding the Proof Pressure causes permanent sensor failure.
P300 Sensors can be easily scaled by the user to read in any pressure unit (psi, kPa, bar, etc.). Contact Pace Scientific for details.
Part No: P300-[specify range]-[specify type]
Example part #'s: P300 for Barometric Pressure: P300-Baro; P300 Pressure Sensor for 10 inch H2O Differential: P300-10in-D
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.
