two chambers closed, the net force resulting from the difference in pressure between the two
chambers is transmitted to the load cell through the coupling. The value of the pressure is
calculated from the effective area of the piston-cylinder and the net force value measured by
the load cell. The 10 kPa/kg piston-cylinder combined with 1.5 kg net measurement span of
the load cell give the FPG8601 a pressure range of 0 to 15 kPa (4.5 inHg).
The FPG8601 Platform is interfaced with the system controller (PC) running FPG Tools
software that calculates pressure and controls the FPG8601 functions.
The PPC3 pressure controller is used to automate pressure control to set the pressure
measured by the FPG8601.
