Abstract

Abstract Method of and apparatus for measuring the diameter of elongated vulcanizable material such as the extruded sheath of a cable as the cable travels through an elongated continuous vulcanizing chamber wherein it is subjected to high pressure and temperature. For carrying out such measuring operation, there is provided a fluid jet probe supplied with fluid under a pressure which is greater than the pressure existing in the vulcanizing chamber, the probe penetrating through the wall of the chamber into the interior thereof with its inner, discharge end close to the surface of the travelling material at a location where the longitudinal axis of the travelling material is fixed in direction radially of the side wall of the vulcanizing chamber and thus is fixed relative to the inner end of the probe. The pressure of the fluid reflected by the surface of the material and the pressure of the atmosphere in the vulcanizing chamber are each transmitted to a differential transducer which translates the difference between the two pressures into an electrical signal which can be interpreted by a read-out device in terms of diameter of the material. By the use of a plurality of probes, disposed around the longitudinal axis of the material, a plurality of differential transducers associated with the respective probes, and one or more read-out devices, the degree of eccentricity of a cable sheath relative to the cable core can be continuously monitored.
