EL-5092BK Explosion-Proof Batch Controller

Current location:Home page -> Product -> System Control Instrument

■Product Introduction
EL-5092B (EL5092BK) series of explosion-proof value control instrument (also known as: loading control device, batch filling controller), widely used in petroleum, chemical products, automatic quantitative loading, barrels, bulk filling control, A variety of medium high-precision mixing ratio distribution, control, and the production process of the middle metering function, is the basic unit of the automated distribution system. The product is in the study of foreign similar products on the basis of advanced technology, in-depth understanding of the actual needs of domestic users, tailored for the Chinese users can completely replace the same type of products at home and abroad.

■Instrument features and functions
EL-5092B series of explosion-proof value of the controller with its advanced technology, beautiful appearance, full-featured, easy to operate, the use of reliable and favored by customers. It uses the industrial CPU microprocessor as the core, with LCD LCD digital and Chinese characters display type to choose from. Circuit design and software design using the watchdog (WDT) processing technology, the power line with a power filter to improve the system's anti-electromagnetic interference, can be widely used for flow measurement display, quantitative loading, barrel And ingredients control and other places of use, with the cumulative flow display, instantaneous flow display, hair data query, multi-stage sequential control, pump control and other functions. Can be used alone to install, but also through the RS-485 communication interface and the computer constitutes an automatic measurement, control management system, to achieve hair oil distribution monitoring, data statistics, printing and network management.

EL-5092BK explosion-proof value of the controller is a series of products in the forward-looking products, which uses high-speed ultra-large-scale enhanced industrial-grade SOC core, non-contact IC card technology and the latest electronic technology, with high precision, Fast, anti-interference ability, communication distance and high-speed and reliable, easy to operate, easy to maintain and so on. Operation of the chassis with flameproof design, internal non-contact IC card reader, can be different non-contact IC card administrator, operator two permissions, the second level password management, display part of the 320x240 dot matrix Screen backlit graphics LCD screen, up to 15 lines of Chinese characters display, display a large amount of information to facilitate customer operation, user-friendly. In order to improve the transparency of the EL-5092B series explosion-proof controller, all the parameters in the machine are open to the user, that is, the operator can know any parameters within the machine through the keyboard. EL-5092B explosion-proof value control instrument with a single quantitative control function. EL-9052BK with a single quantitative, dual-way quantitative and other control methods. Compared with the domestic similar products, the series of products not only technology leadership, at the same time with the prospective superior performance, intuitive operation interface, petrochemical industry storage and transportation sector is the preferred product.
