The filling scale instrument is a special intelligent instrument for static and dynamic measurement. It integrates the measurement and control functions, and is used in conjunction with the constant speed, speed regulation, weight loss and other scales to realize the weighing and batching of various materials. The instrument adopts high performance , High anti-interference, industrial-specific single-chip microcomputer, with RS-485 communication interface, can be easily connected to the DCS system. The intelligent PID output can perform closed-loop control of the actuators such as frequency converters.

Filling scale instrument features:

Filling scale instrumentIt is mainly designed and developed based on the actual experience of more than a thousand belt scales and control parts used in various parts of the country. It removes the complicated operation of imported instruments, and adopts the form of man-machine dialogue to display directly in Chinese (Chinese characters are 16X16 dot matrix). All kinds of related information, operation and calibration are particularly convenient. It has functions such as automatic zero point calibration, automatic interval calibration, fault self-diagnosis, high flow, low flow alarm, multiple input\/output, etc., and has a variety of communication protocols.

The filling scale instrument adopts a variety of communication functions, these communication functions allow the instrument to be connected with computers and printers, and the input\/output functions can be used to drive relays, motor starters, switches, etc.
