【 Sensor Property Conversion 】

Voltage pressure conversion type: Pressure = ( Vout + VDD ×0.04[V] ) / ( VDD × 0.004[V/kPa] )

Maximum pressure iPhysics_max  250.0[kPa]
Minimum pressureiPhysics_min20.0[kPa]
Maximum voltageiVout_max250[kPa]×0.004×VDD – VDD×0.04[V][V]
Minimum voltageiVout_min20[kPa]×0.004×VDD – VDD×0.04[V][V]
