METHOD AND DEVICE FOR DETERMINING THE BOILING TEMPERATURE

摘要

ALFRED TEVES GMBH P 6135 (2127R) PHYWE AKTIENGESELLSCHAFT Method and Device for Determining the Boiling Temperature To determine the boiling temperature of a liquid, e.g. a hygroscopic brake fluid, a probe (1, 1') is immersed partly, that is to say until an exactly predefined depth, into the test liquid. The probe (1, 1') contains a measuring unit (14) which incorporates a temperature sensor (17) and which is in communication with the test liquid via a supply bore (13). The upper part of the measuring unit (14) forms a condensation zone (15) which is connected to the atmosphere via discharge openings (16). On ebullition of the test liquid, a bubbles or foam boiling zone (22) is formed directly on top of the surface (21) of the liquid, and on top of the zone (22) a condensation zone (15) is formed, out of which the condensate flows off to the outside. The temperature in the bubbles boiling zone is measured by means of the temperature sensor (17). (Fig. 1)
