Central Circle Chart Automatic Balance Recorder

1、 Overview of the Circular Chart Automatic Balance Recorder
The automatic balancing recorder of the central circle chart cleverly applies advanced technology introduced to this instrument, making it highly cost-effective. This instrument has the characteristics of simple structure, high sensitivity, stable recording, and easy maintenance.
The automatic balance recorder for the medium circle chart is a product specially developed based on the characteristics of industries such as metallurgy, electric furnaces, heat treatment, and food processing. In the heart of the instrument (balance sliding resistance), this product uses a conductive plastic potentiometer, which improves resolution and has a service life more than ten times longer than the precious metal winding type. It replaces the traditional circular diagram multi gear transmission structure, reduces instrument components, and thus improves the reliability of the instrument. The product adopts high-tech optoelectronic integrated circuit technology to control the alarm system, which has many characteristics and advantages such as independent alarm, high alarm accuracy, and light instrument weight.
