KEY ELECTRICAL COMPONENTS FUNCTION
PT1:
PT1 is a 0--225 psi gauge pressure transducer that measures discharge air pressure.
PT2:
PT2 is a 0--100 psi gauge pressure transducer that measures regulation system pressure.
U1:
U1 is resistive level detector that measures the fuel level in the fuel tank.
It provides a continuous reading of fuel level. It also has a switch for low fuel level and low fuel shutdown.
These switches connect to WEDGE.
RT1:
RT1 is a 10K ohm Thermistor temperature sensor that measures separator tank temperature.
Its range is --30 to 255
