摘要： Systems and methods for air pressure control in a hot melt liquid dispensing system are described. An example hot melt liquid dispensing system includes a pump that pumps hot melt liquid to an applicator. The hot melt liquid dispensing system also includes an air flow path that supplies pressurized air to the pump and an electronic pressure sensor associated with the air flow path. The hot melt liquid dispensing system also includes a controller that receives an electronic signal from the electronic pressure sensor indicative of an air pressure in the air flow path and causes adjustment to the air pressure in the air flow path based on the electronic signal from the electronic pressure sensor.
