Claim:
1. A sealed, immersible, coaxial thermocouple assembly for fast temperature reading of a liquid stream in a mixing valve, comprising a wire comprising a first-metal and a surrounding tube comprising a second-metal; a tip portion of said tube is crimped at a first end of said tube over an extremity of said wire to press said tip portion of said tube against said extremity of said wire to form a thermocouple junction including electric contact between the wire and the tube; said tip portion is shaped by said crimping as a radial array of axially extending fins said thermocouple assembly further comprising a fastener fixing said tube into a mixing valve, such that the liquid stream flows from the mixing valve through an outlet of the valve axially along said tip portion and at least a substantial portion of said tube length.
