Abstract: An apparatus for determining and/or monitoring a process variable, for example, temperature, flow or flow velocity, of a medium in a containment includes a temperature sensor for registering temperature securable to an outer surface of the wall of the containment, at least one connection line for electrical contacting of the temperature sensor, and securement means for a releasable securing of the temperature sensor and a temperature sensor-near section of the connection line to the outer surface of the wall of the containment. According to the present disclosure, at least the section of the connection line is securable to the outer surface of the wall of the containment such that the section extends parallel with the wall of the and is in thermal contact with the wall of the containment.

Abstract: A motor vehicle with a wheel, a wheel case enveloping the wheel, and an air duct leading to the wheel case, wherein the air duct incorporates an adjustable element, which in a first position steers the air entering into the wheel case through the air duct into a gap between an inner flank of the wheel and an inner wall of the wheel case, and in a second position diverts the air by an outer flank of the wheel.
