To which spray system component should the pressure gauge sensor line connect?

The pressure gauge sensor line should connect to the boom. In aerial application, the boom is the horizontal structure from which nozzles are suspended and through which the spray mixture flows. Monitoring pressure at the boom provides critical information about the spray system's performance, including detecting any variations in pressure that can affect the uniformity of the spray pattern and the application rate.

Connecting the pressure gauge to the boom allows operators to closely monitor the pressure just before the spray enters the nozzles. This is essential for ensuring that the system is functioning correctly, maintaining accurate and effective pesticide or fertilizer application. Proper pressure monitoring can help prevent issues such as overspray or underspray, which can lead to ineffective treatments or environmental harm.

In this context, the other components like the tank, nozzle, and line filter play different roles. For instance, while pressure in the tank is important for overall system function, the direct measurement of pressure relevant to precise application occurs at the boom, where it directly impacts the performance of the nozzles. This is crucial for effective aerial spraying operations, making the boom the correct choice for the connection of the pressure gauge sensor line.
