These switches monitor fluid or gas pressure in hydraulic, pilot, brake, engine oil, fuel, or air conditioning systems. At preset pressure thresholds, they send electrical signals to activate warning lights, safety interlocks, or system shutdowns.
Sensor switches (also referred to as sending units or intelligent switches) provide continuous or threshold-based signals to Liebherr’s Litronic electronic control system. These integrate pressure sensing with electronic output (analog or PWM) for real-time monitoring and diagnostics.
