Product details
Circular chart automatic balancing paper recorder
The paper recorder for automatic balancing of the circular chart adopts a modular design, with feedback from conductive plastic potentiometers and a precision magnetic motor driven recording mechanism; Digital display and circular chart recording; Reasonable structure, high precision, stable and reliable. Commonly used in batch processes to display batch runs within a specific time period from 1 hour to 31 days. Its advantage is that it is easy to fill in and copy, for future reference. Compared to long image recorders, it has a shorter adjustable drawing width.
The paper recorder instrument for automatic balancing of the central circle chart adopts an internationally advanced switching power supply, which has greatly improved its resistance to various power interferences and can work normally in areas with extremely wide AC voltage fluctuations. The instrument structure adopts a building block form, which changes the traditional manufacturing process and reduces the number of instrument components, thereby improving the reliability of the instrument. In addition to the traditional recording function, this instrument also adds digital display to make the measured values clear at a glance. The automatic balancing of this circular chart with a certain transmitter can be widely used in enterprises such as textile, food, environmental protection, chemical, mining, metallurgy, petroleum, power generation, and scientific research units to automatically measure, indicate, and record the measured parameters.
