Abstract
Sensors (18, 20 and 22) and an interactive display (12) are added to an airless gas powered line striping machine (10) to provide the operator with a variety of information about the operating parameters. In addition to the pressure sensor/transducer (14) required to control the pressure through a clutch, the system includes a sensor (reed switch in the preferred embodiment) (18) to count pump strokes or drive revolutions, a sensor (22) to monitor when the gun trigger is activated and a sensor (26) to monitor wheel rotation (hall effect sensor detecting pulses from gear mounted on wheel in the preferred embodiment). A digital display (12) is included to read out measured and calculated values.
