发明名称 Fluid boiling-point sensing device
摘要 PCT No. PCT/GB95/00543 Sec. 371 Date Dec. 9, 1996 Sec. 102(e) Date Dec. 9, 1996 PCT Filed Mar. 13, 1995 PCT Pub. No. WO95/24646 PCT Pub. Date Sep. 14, 1995A Portable Fluid Boiling Point Sensing Device (1) which can be used to measure the boiling point of fluids. The device includes a probe (2) for immersion in fluid to be tested, in particular in fluid reservoir. The probe (2) comprises a casing (2a) defining a chamber (3) for a semi-encapsulated portion of fluid (3a). The fluid (3a) kept at an optimum level without sensitive probe (2) depth measurement by a quantity of air (4) being trapped above an aperture means (6a) on the casing (2a) causing an artificial fluid level (L1) to be maintained below the surface of the test fluid. A heater (8) and a temperature sensor (9) are present in the housing (2a) and apertures (5, 6a, 6b) are provided to permit fluid flows into and from the chamber (3). The device senses the boiling temperature of the fluid by measuring the temperature of the vapors (11) given off the heated fluid (3a) within the housing (3), or alternatively directly from the fluid (FIG. 5a/b).
