Pressure Switches Data Sheet: 800-001/18 SMARTSTAT OPERATION The input pressure applied to the Smartstat is converted to a proportional electrical signal by the silicon pressure sensor. After amplification this signal inputs directly into the analogue to digital (a/d) port on the microprocessor. The microprocessor continuously calculates the pressure from the input signal, compares this to the switch setpoints and operates the relays as required. If the pressure rises above the UPPER switch point the relay changes over from normally closed (NC) to normally open (NO), as the pressure falls below...
