Abstract

The invention concerns an induction proximity sensor (S) designed for high temperature and/or high pressure applications essentially comprising a cylindrical housing (1), a front membrane (2), at least one oscillator coil (4) with ferrite core (17) and an electronic system. Magnetic wires of the oscillator coil (4), which are preferably made of silver, nickel, platinum or copper alloys, are insulated with ceramics. The membrane (2) and optionally a head part (5) of the housing in the region of the membrane are advantageously made of a metallic material resistant to high temperatures and thermal shocks, and does not bring about on the nominal temperature range any attenuating variation or causes an attenuating variation countering field loss in the oscillator coil (4).
