Embodiment Construction

[0011] As shown in the figure, the measured solution pool (i.e. the solution measuring pool) 8 is placed in the capacitor cell seat 9, the outer layer of the capacitor cell seat 9 is a constant temperature chamber 4, and the inner wall of the capacitor cell seat is a temperature-resistant insulating layer, such as poly Vinyl fluoride, etc. The chamber body of the constant temperature chamber 4 is provided with a sealing cover 14, a sealing ring 15 and a constant temperature liquid outlet 16 to ensure the sealing of the constant temperature chamber and facilitate the circulation of the constant temperature liquid. Capacitor cell cover 10, cover on the capacitor cell seat. The capacitor cell cover is provided with two metal electrodes 11 extending into the capacitor cell seat, one is a metal column and the other is a ring 12, and the two metal electrodes are spaced apart, and are installed on a polytetrafluoroethylene insulating pad or an insulating plate 2 1. An electrode outl...

Abstract

A new type of capacitor cell, which consists of a capacitor cell and a capacitor cell seat. The capacitor cell seat is a measured solution pool with a constant temperature chamber on the outer layer. One metal electrode extending into the capacitor cell seat, and two metal electrodes extending into the capacitor cell seat are fixed on the insulating plate. The invention solves the operability during measurement and improves the comprehensive performance. Overcome the problems of the old capacitor pool. There is no connection gap between the constant temperature liquid and the measured solution, which fundamentally solves the problem of liquid leakage. The measuring electrode is inserted from the top, which is convenient for liquid addition and cleaning after measurement. Measurements can also be done for less volatile solutions.

Description

1. Technical field [0001] The invention relates to a device applied to the measurement of dielectric constant, in particular to a capacitance pool structure. 2. Background technology [0002] The invention relates to a device for measuring the dielectric constant of a liquid, which is to measure the dielectric constant of a liquid by a solution method. Traditional capacitor pool structures such as figure 1 As shown, the capacitor pool has a three-layer coaxial annular structure as the main body, and the material is copper or aluminum, and the surface is treated with anti-oxidation. exist figure 1 It can be seen in the figure that the inner and outer walls of the capacitor cell are used as the bipolar rice of the measured solvent to be drawn out by two lead wires, and the inner wall is actually a solid copper cylinder. The cavity between the inner and outer walls (as a bipolar plate) is used as the measured solution cavity, and the injection and withdrawal of the measured ...
