Abstract
The invention discloses a water level detector, comprising a probe, a lead, a mounting base and a separation blade. A mounting side of the mounting base is planar; a probe head of the probe projects out from the lower surface of the mounting side of the mounting base; the lead is connected with the tail of the probe; and the separation blade is mounted at the mounting side of the mounting base. The separation blade structure is arranged in the water level detector disclosed by the invention; in a stirring process of an inner tank of a calorimeter after constant volume is set, the liquid in the inner tank forms an eddy current, and the eddy current is blocked by the separation blade in the rotation process, so that the liquid level at a land side of the separation blade declines; since the probe head is arranged at the land side of the separation blade, the liquid level surrounding the probe head declines under the effect of the separation blade declines, the probe head is prevented from being soaked by the liquid in the inner tank, therefore, the problem of loss of accuracy of the probe head caused by pollution and oxidation is solved; and the water level detector disclosed by the invention is simply structured and cannot interrupt liquid level detection of the probe.
