摘要： The invention relates to a measuring instrument for time-variable magnetix fluxes, or flux gradients, to electrical resistance elements, and to a measuring system comprising a measuring instrument or electrical resistance element according to the invention. The core component of the measuring instrument is a flux transformer composed of a base material which has a phase transition to the superconducting state. According to the invention, even when the base material is in the superconducting state, this flux transformer comprises at least one load region having electrical resistance that is other than zero for dissipating the electric energy in the conductor loop thereof. For this purpose, according to the invention the conductor loop and the magnetic field source are disposed in one plane and are typically photolithographically structured. The resistance elements according to the invention, having resistance values of ≦10−4Ω, are used as core components in the measuring instrument. According to the invention, measurement is possible in a broader frequency range, with less noise and with greater sensitivity than was possible with generic measuring instruments or measuring systems.
摘要翻译： 本发明涉及一种用于时变磁通量或通量梯度到电阻元件的测量仪器，以及包括根据本发明的测量仪器或电阻元件的测量系统。 测量仪器的核心部件是由与超导状态相变的基体材料组成的磁通变压器。 根据本发明，即使当基材处于超导状态时，该磁通变压器包括至少一个负载区域，该负载区域具有不为零的电阻，用于耗散其导体环路中的电能。 为此，根据本发明，导体环路和磁场源设置在一个平面中，并且通常是光刻结构的。 根据本发明的电阻值为“n”; 10-4＆OHgr的电阻值被用作测量仪器的核心部件。 根据本发明，可以在更宽的频率范围内进行测量，噪声小，灵敏度高于通用测量仪器或测量系统的灵敏度。
