Claims (4)

1. Vorrichtung zur Druckerfassung in Hydraulikleitungen, mit einem Drucksensor, welcher der Hydraulikflüssigkeit ausgesetzt ist, wobei in der Hydraulikleitung dem Druck­ sensor ein Leitungsabschnitt vorgeschaltet ist, der eine gleichmäßige Druckausbreitung störend ungeradlinig und/oder mit wechselnden Querschnitten ausgestaltet ist, dadurch gekennzeichnet, daß die Vorrichtung einen elektronischen Drucksensor aufweist.1. Device for pressure detection in hydraulic lines, with a pressure sensor which is exposed to the hydraulic fluid, wherein in the hydraulic line, the pressure sensor is preceded by a line section which is designed to have a uniform pressure distribution which is disruptively uneven and / or with changing cross sections, characterized in that the Device has an electronic pressure sensor. 2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Leitungsabschnitt (5) eine mehrfache Richtungs­ umlenkung der hydraulischen Leitung aufweist.2. Device according to claim 1, characterized in that that the line section (5) a multiple direction  has deflection of the hydraulic line. 3. Vorrichtung nach Anspruch 1 oder 2, dadurch gekenn­ zeichnet, daß der Leitungsabschnitt (5) und der Druck­ sensor in einem gemeinsamen Gehäuse angeordnet sind.3. Device according to claim 1 or 2, characterized records that the line section (5) and the pressure sensor are arranged in a common housing. 4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß das Gehäuse mehrteilig aufgebaut ist.4. The device according to claim 3, characterized in that the housing is constructed in several parts.
