"I've built the R290 PT Chart into the software, and that pressure sensor is a Carel ratiometric. The LCD gives me the saturated suction temperature (SST), and also the real temperature from the little silver probe (A Dallas DS18B20 digital unit) so I can instantly see the real-time evaporator temperature and superheat. The rotary encoder on the panel allows me full manual control over the EEV, so I can twiddle the knob and observe the effects."
