Abstract: A measuring system for detecting a physical parameter, includes a measuring sensor for detecting the physical parameter, which sensor has a first, second and at least one third terminal. The measuring system also includes a first power supply unit for outputting electrical energy to the measuring sensor with a first voltage with respect to a first ground potential via the first and the second terminal, and a second power supply unit for outputting electrical energy to the measuring sensor with a second voltage with respect to a second ground potential via the third and the second terminal or a fourth terminal. The first ground potential can differ from the second ground potential at least temporarily. The first power supply unit includes an additional voltage source via which the second terminal is electrically connected to the first ground potential.

Abstract: A valve device or a vehicle system, the system including first and second control units which are electrically connectable or connected to the valve device, which includes a valve unit with at least one actuator for actuating the valve unit, first/second supply ports for the electrical connection of the actuator to the first/second control units, first/second main ports for the electrical connection of the actuator to the first/second control units, first/second electric protective circuits, and a valve housing for accommodating the valve unit and the protective circuits. The first protective circuit is electrically connected between the first/second supply ports, and the actuator. The second protective circuit is electrically connected between the actuator and the first/second main ports. Each protective circuit includes an electrical fuse device and a diode element that are integrated in series in at least the first/second supply ports or at least the first/second main ports.

Abstract: A valve-device (VD) for a vehicle-braking-system (VBS), and a VBS. A VD for a VBS, having first/second control-units (CU), which are electrically connectable to the VD, which includes a valve-unit (VU) with an actuator for actuating the VU, a valve housing (VH) for the VU, and an error protection module (EPM) outside the VH. The EPM includes first/second supply-ports (SP) for electrical attachment to the first/second CUs, first/second main-ports (MP) for electrical attachment to the first/second CUs, a first connection port (CP) electrically connected to the first/second SPs, for electrical connection to the actuator, a second CP electrically connected to the first/second MPs, for electrical connection to the actuator, first and second electric protective circuits (EPC). The first EPC is electrically connected between the first/second SPs, and the first CP. The second EPC is electrically connected between the second CP and the first/second MPs.
