Abstract:
A high pressure threshold detection circuit (100) is provided. The high pressure threshold detection circuit includes a pressure transducer (110) for measuring a pressure of a medium at an outlet (104) of a compressor (102). The high pressure threshold detection circuit (100) includes a controller (120). The controller (120) includes a comparator (123) and a switch (125). The comparator (123) and the switch (125) are electrically coupled. The switch (125) is electrically coupled to an enable circuit (131). The pressure transducer (110) is electrically coupled to the comparator (123) to provide a signal to the comparator (123) based on the pressure measured at the outlet (104). The comparator (123) outputs a control signal (111) to the switch (125) when the signal (111) is equal to or greater than a reference value (126). The switch (125) opens the enable circuit (131) to disable compression of the medium by the compressor (102) in response to the control signal (111).
