Pressure/Force
Pressure is defined as force per unit area that a fluid exerts on its surroundings. For example, pressure, P, is a
function of force, F, and area, A.
P = F/A
Data from pressure/force channels is converted using the following equation:
Where:
P = Pressure
S = the sensitivity of the gauge in mV/V
O
fs
= the Full Scale Output (Output
fs
)
V
m
= the measured voltage
V
ex
= the excitation voltage
