20 20 Temperature is controlled by providing a solid state relay with a 1 second (period) pulse width modulated signal in order to provide the desired average power delivery. The PWM signal is generated using an NI-9472 digital output module within a Compact RIO chassis.

31 31 In order to prevent liquid water from reaching the Alicat flow controller and Aerodyne analyzer we have created a system which will stop flow by powering off the Alicat flow controllers upon successful detection of liquid water. This system consists of 6 major components:

39 39 The basis of this design is to cut power to the Alicat Power Distribution Unit (PDU) upon detection of liquid water.
40 40 The RT controller has FPGA software installed to disable the output of CH7 of the digital output module, which in turn disengages the mechanical relay, upon an input signal on CH0 of the digital input module.
