A wireless sensor for detecting electrolyzer voltage and electrolyte temperature

Abstract

The invention provides a wireless sensor used for detecting the voltage of an electrolytic bath and the temperature of an electrolyte. The wireless sensor is characterized in that the wireless sensor comprises a data acquisition circuit used for acquiring a bath voltage signal and an electrolyte temperature signal, a power supply circuit is used for providing electric power to the data acquisition circuit and a wireless transmission circuit, and bath voltage and electrolyte temperature obtained by the data acquisition circuit are transmitted to a monitoring system through the wireless transmission circuit. The sensor provided by the invention can automatically obtain bath voltage and electrolyte temperature and eliminates troubles in manual measurement; and since a wireless mode is used for data transmission, the service life and reliability of the sensor are improved.

Description

technical field [0001] The invention relates to a wireless sensor used for detecting the voltage of the electrolytic cell and the temperature of the electrolyte in the production process of electrolytic copper. Background technique [0002] In the electrolytic copper process, the voltage of the electrolytic cell and the temperature of the electrolyte are important parameters to characterize whether the electrolytic cell works normally. During the electrolysis process, the change of the electrolytic cell voltage directly affects the quality, appearance and energy consumption of electrolytic copper; the temperature directly affects the quality, energy consumption and consumption of the cathode copper. [0003] At present, in the copper production system, the single cell voltage and electrolyte temperature of the electrolytic cell are measured mainly by manual interval time measurement. This measurement method is difficult to track and monitor the cell voltage and temperature ...

Problems solved by technology

Although this method reduces the need for manual measurement, complex hard-wire systems are difficult to maintain stability and require a huge investment for tens of kilometers of hard-wire connections, optical voltage isolation devices, calibration and voltage difference measurements.

In particular, hard-wire systems are often located in corrosive media and a large number of magnetic fields, which is a severe challenge
