Paint gun, material application system, and method for operating same

A paint spray gun for atomization and application of a paint, the paint spray gun comprising:

• a material-conveying portion into which a material channel system opens, the material-conveying portion including:
• a material feed configured for receiving the paint;
• a nozzle head;
• and
• the material channel system which leads to the nozzle, the material channel system being configured for conveying the paint from the material feed to the nozzle head;
• a non-material-conveying portion of the paint spray gun;
• a transmitting and receiving device configured for bidirectional wireless data transmission;
• and
• a compressed air connection and a compressed air line system, the compressed air line system being configured for guiding compressed air from the compressed air connection to the nozzle head,
• wherein the transmitting and receiving device is at a distance from the material-conveying portion and is associated with the non-material-conveying portion,
• wherein the transmitting and receiving device is configured for wireless data transmission according to a first radio standard, and is additionally configured for wireless data transmission according to a second radio standard,
• wherein the second radio standard is suitable for wirelessly transmitting data over a wider range than the first radio standard,
• wherein the paint spray gun further comprises a first pressure measuring channel that is routed from a first compressed air chamber in the material-conveying portion of the paint spray gun to a first pressure sensor, the first pressure measuring channel being different than the compressed air line system that guides compressed air from the compressed air connection to the nozzle head,
• wherein the first compressed air chamber is formed by or arranged in an atomization compressed air region in the material-conveying portion of the paint spray gun, and the first pressure sensor is configured to measure air pressure in the atomization compressed air region, and
• wherein the first pressure sensor is at a distance from the material-conveying portion and is associated with the non-material-conveying portion.
