Abstract: A sensor of the inductive type comprising at least one support, wherein the support is provided with at least one coil, and wherein the coil is adapted to be fed with a high- frequency signal. The coil or each coil part thereof has its respective windings arranged in one plane and the support is formed of a disc-shaped substrate having a deformation temperature which is at least 1000°C. The windings are provided on the substrate by vapour deposition or etching. The sensor is adapted for operation selected in the frequency range of 1 MHz - 1 GHz. Through the substrate and in the centre of said at least one coil there may be arranged a core of ferromagnetic material. The sensor is expediently embeddable with the aid of glass ceramic material or glass material in an aperture in a holder of metal or metal alloy. The sensor is, for example, useful for multiphase measurement of a fluid flow containing a fraction of water, at a pressure selected in the range of 0 - 1500 bar and a temperature selected in the range of from -5O°C to +25O°C. The sensor is particularly useful in a sensor device in which with the aid of glass ceramic material or glass material there is embedded in at least one aperture in the holder a respective capacitive sensor, the holder via an intermediate piece being connected to an attachment flange designed for mounting on pipeline equipment which carries said fluid, so that the holder when so mounted penetrates into the fluid flow. Thus, said water fraction can be detected capacitively and at least partly inductively in a first measuring range and detected inductively in a second measuring range.
