摘要： A sensor used especially for the measurement of the internal pressure of injection lines of diesel engines comprises two housing parts which are connected via an articulation and can be clamped to the line with a tension device. For simple and in particular one-handed attachment of the sensor in every state of opening or closing, the tension device is located in the same sector, facing the articulation, on one side of the external region of the tube. The connecting plug for the discharging of the measuring signals is preferably insertible in the correspondingly fashioned articulation and can be locked there.

摘要： A sensor is provided that can be used for measuring the internal pressure of injection lines of diesel engines includes two housing parts that are connected via a joint and can be clamped to the injection line using a clamping device. At least one electrical measuring element is pressed, in essentially uniform elastic fashion, onto the surface of the hollow body to be measured. The sensor also includes a support element that operates essentially in radial fashion. A protective film is arranged between the surface and the measuring element. The protective film has a thickness greater than or equal to the radial dimension of foreign bodies or the like that are to be expected on the surface of the hollow body to be measured. The protective film consists of plastic with a low modulus of elasticity. In this way, impurities, burrs and the like on the tube can easily be "embedded" in the protective film, which, as a result of the low elasticity modulus, nonetheless still ensures a sufficiently good transmission to the measuring element of the surface expansions actually to be measured.

摘要： For largely automatic determination of the moment of inertia of, in particular, an internal combustion engine on a testing stand, speed n and indicated torque M.sub.M are measured under controlled operating conditions in both a run-up phase as well as in a coasting phase. In order to eliminate the loss moment in the determination of the moment of inertia, the measuring points of the respectively same speed from the run-up phase and the coasting phase are interpreted in combination, this enabling an exact determination of the moment of inertia in a very simple way with the devices that are usually already present at a testing stand.
