What is one main function of the pressure gauge on a hydraulic sprayer?

The pressure gauge on a hydraulic sprayer serves the essential function of monitoring the pressure within the system. This is critical for ensuring that the sprayer operates at the optimal pressure levels necessary for effective pesticide application. Accurate pressure readings allow the operator to maintain the proper pressure, which affects the spray pattern, droplet size, and overall efficacy of the application. Monitoring pressure helps to prevent problems such as inadequate coverage or potential damage to the plants due to over-pressurization. By knowing the pressure, applicators can make required adjustments to ensure uniform distribution and safe pesticide usage, which contributes to both efficacy and environmental safety.
