Abstract
A fluid sampling probe includes a fluid sampling conduit surrounded by a sheath. Cooling fluid passes through the annulus between the fluid sampling conduit and the sheath to cool the fluid samples passing through the fluid sampling conduit. A thermocouple has its sensing end located in the annulus to monitor the temperature of the cooling fluid.
Claims3
A probe for obtaining high temperature fluid samples comprising:
- (a) a fluid sampling conduit through which the fluid samples pass,
- (b) a sheath surrounding said fluid sampling conduit along a portion of its length to form an annulus between said fluid sampling conduit and said sheath,
- (c) a supply of cooling fluid,
- (d) a cooling fluid conduit for providing cooling fluid flow through said annulus to cool the fluid samples flowing through said fluid sampling conduit,
- (e) a thermocouple having its sensing end located within said annulus to provide a signal representative of the temperature of said cooling fluid, and
- (f) means for deflecting the cooling fluid exiting from said annulus away from the sampling end of said fluid sampling conduit.
