Small High-Speed High-Precision Dynamic CheckweigherScope of Application:

This product is suitable for online automatic weighing detection, underweight detection, missing installation detection, and missing accessory detection of small packaging boxes, small bags, and extremely small individual items; widely used in electronics, pharmaceuticals, food, beverages, health products, daily chemicals, light industry, agricultural by-products, and many other industries.

Small High-Speed High-Precision Dynamic CheckweigherProduct Features:

l Strong Versatility: Standardized structure and standardized human-machine interface can complete the weighing of various materials;

l Simple Operation: Uses Weiren color human-machine interface, fully intelligent and user-friendly design; conveyor belt is easy to disassemble and install, convenient for maintenance and cleaning;

l Adjustable Speed: Uses frequency conversion control motor, speed can be adjusted as needed;

l High Speed, High Precision: Uses high-precision digital sensors, fast sampling speed, high precision;

l Zero Tracking: Can manually or automatically reset to zero, as well as dynamic zero tracking;

l Report Function: Built-in report statistics, reports can be generated in EXCEL format, can automatically generate various real-time data reports,

External USB interface, can insert U disk to export data in real time, grasp production status at any time; provides factory parameter setting recovery function, and can

Store multiple formulas, convenient for changing product specifications;

l Interface Function: Reserved standard interface, convenient data management, can communicate and connect with PC and other intelligent devices;

l Self-Learning: After creating new product formula information, no need to set parameters, use self-learning function to automatically set suitable device parameters, and store for easy recall when switching products next time. (Parameter storage capacity 2000 entries, can be increased).

l Operation Mode: Three operation modes

a. Dynamic Mode: Normal assembly line mode;

b. Static Mode: After material enters the weighing platform, the platform stops running to perform weighing to improve precision, suitable for products with less than 20 passes per minute;

c. Energy Saving Mode: (Optional) Can activate energy saving mode based on a or b mode, set no material pass shutdown time, when the device idles for this duration, it automatically shuts down, and automatically starts when material passes again.

l Fault Self-Detection: Can self-detect: motor, frequency converter, AD, sensor and photoelectric status and fault causes, as well as guided detection of cylinders, solid-state relays, and solenoid valves. Convenient for non-professionals to inspect and maintain.

l Peripheral Device Communication: Standard equipped with RS-485 and RS-232 dual communication port outputs.

a.RS-485 interface is MODBUS, RTU standard protocol but can self-modify write address (57600bps, 8, N, 1, slave station number 3) cannot be modified.

b.(Optional)RS-232 interface is custom protocol, can self-set command sending content. (57600bps, 8, N, 1) can be modified.

l Can connect to external printers or coders and other communicable devices, can also connect to front and back end packaging machines and production equipment to feedback weighing results enabling automatic modification of formula parameters.

l Chinese Input Method

a.Formula names etc. can input Chinese, more intuitive when searching and switching formulas.

b.Combined with RS-232 communication port, can send Unicode string Chinese characters to peripheral devices. (Suitable for external printers or marking machines that need to print Chinese characters).www.ledingzn.com
