The differential switch 99749200 functions as a safety and control device designed to detect variations in pressure, flow, or levels between two distinct points in a system. By monitoring these variables, the switch activates or deactivates an electrical circuit once a predetermined threshold is met. This component is integrated into the hydraulic, pneumatic, or filtration systems of the machine to ensure that operational parameters remain within defined safety limits.
This part is specifically engineered for the Demag AC 615 all-terrain crane. It serves as a critical interface within the control architecture, potentially monitoring pressure levels in hydraulic circuits or airflow in braking systems to prevent system failures. The device operates using internal mechanisms such as diaphragms, bellows, or pistons that react to pressure differentials between two ports. When the force generated by this difference exceeds the set point, it engages an internal microswitch to signal the control system.
Differential switches are used in heavy machinery to provide feedback on system health by detecting blockages, pressure drops, or flow imbalances. By providing an automated response to these changes, they assist in protecting the machine from overloads or hydraulic malfunctions that could occur if the system operates outside of its intended range.
