Description

(54) БЕСКОНТАКТНЫЙ КОНДУКТОМЕТРИЧЕСКИЙ ДАТЧИК(54) NON-CONTACT CONDUCTOMETRIC SENSOR

II

Изобретение относитс  к измерению злектрической проводимости жидкостей бесконтактным способом.This invention relates to the measurement of the electrical conductivity of liquids in a non-contact manner.

Известен по основному авт. св. : № 595668 бесконтактный кондуктометрический датчик, который содержит два сердечника с обмо.тками, причем питающа  обмотка соединена с генератрром переменного напр жени , а приемна  - с источником напр жени , управл емым током, выход зтого источника соединен с измерительным прибором. Св зь между питающей и приемной обмотками осуществл етс  жидкостньм . контуром. Known for the main author. St. : No. 595668 is a contactless conductometric sensor that contains two cores with coils, the supply winding is connected to an alternating voltage generator, and the receiving winding is connected to a voltage source controlled by a current, the output of this source is connected to a measuring device. The connection between the supply and the receiving windings is liquid. contour.

В этом датчике устранено вли ние температурной нестабильности параметров сердечника приемной обмотки, что позвол ет повысить точность измерений .1 1.This sensor eliminates the effect of temperature instability of the parameters of the core of the receiving winding, which makes it possible to increase the measurement accuracy .1 1.

Недостатком датчика  вл етс  ограниченна  точность измерений, котора , обусловлена нестабильностью па-. . раметров сердечника питающей обмотки и подк.гаоченного к ней генератора переменного напр жени .The disadvantage of the sensor is the limited measurement accuracy, which, due to the instability of the pa. . The cores of the power winding and the alternating voltage generator that is attached to it are alternating.

Цель изобретени  - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.

Поставленна  цель достигаетс  тем, что в бесконтактном кондуктометрическом датчике источник напр жени , подключенный к питающей обмотке, выполнен регулируемым, в датчик дополнительно введены петл  из токопровод 10 щего материала, охватывающа  сердеч- . НИКИ датчика, детектор, схема сравнени , источник опорного напр жени  и интегратор, причем вход детектора соединен с концами упом нутой петли, The goal is achieved by the fact that in a contactless conductometric sensor the voltage source connected to the supply winding is adjustable, a loop of conductor 10 is added to the sensor, covering the heart. NIKI sensor, detector, comparison circuit, reference voltage source and integrator, with the detector input connected to the ends of the loop,

ts а выход - с первым входом схемы сравнени , к второму входу которой подключен источник опорного напр жени , выход схемы сравнени  соединен с входом интегратора, выход которого ts and the output to the first input of the comparison circuit, to the second input of which the reference voltage source is connected, the output of the comparison circuit is connected to the input of the integrator, the output of which

20 подключен куправл ющему входу источника напр жени  питающей обмотки.20 is connected to the control input of the supply voltage of the supply winding.
