Abstract:
A magnetic flowmeter has a pair of coils each comprising a conductive pattern carried by a flexible insulating base. Each insulating base is wrapped partially around and secured to a cylindrical tube constructed of electrically insulating material. The patterns can be easily designed to produce a desired magnetic field pattern.
Abstract:
A durable sensor for accurately measuring the temperature of heated rubber material in a curing mold is made of a sturdy construction to withstand the mechanical stress that is applied to it while each successive cured part is stripped from the mold and from about the sensor. The sensor includes a probe on which a pair of wires forming a thermocouple are mounted. The probe has the same thermal characteristics as the rubber material under measurement. A thin support sleeve which is thermally isolated from the mold protects and strengthens the probe. This construction prohibits any heat emitted by the mold from adversely affecting the accuracy of the measurement of the temperature of the rubber material.
