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. The capacitor pool is a cover shape 10, which is covered on the capacitor pool seat. The cover-shaped capacitor cell is provided with two metal electrodes 11 extending into the capacitor cell seat, one is a metal column and the other is a ring shape 12, and the two metal electrodes are spaced apart, and are installed on a polytetrafluoroethylene insulating pad or an i...

Abstract

The novel capacitive pool structure includes capacitive pool and capacitive pool seat. The capacitive pool seat is one tested solution pool with constant temperature cavity around it, and the capacitive pool is one cover set on the upper part of the capacitive pool seat. The capacitive pool has two metal electrodes stretching into the capacitive pool seat and fixed onto an insulating board. The present invention is test operable and superior to available capacitive pool, and has improved comprehensive performance. Without connecting cracking between the constant temperature liquid and tested solution, the present invention has no liquid leakage. The measuring electrodes are inserted from the upper end for convenient liquid refilling and washing after measurement. The measurement to non-volatile solution is also feasible.

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 ...
