FIELD: measuring technique. ^ SUBSTANCE: measuring device has a chamber with dielectric walls, a source of high-voltage tension and control arrangement. At that on the inner opposite walls of the dust precipitation chamber two pairs of corona-forming and grounded electrodes are located and the control arrangement has two control blocks, two circuit breakers, a contactor, a resistive divider of tension, a comparator and a block of synchronization. ^ EFFECT: increases accuracy of measuring. ^ 2 dwg |
