Features
This wall-mounted belt weigher weight control instrument developed for belt conveyor batching (constant flow rate batching control/constant weight batch control). It features complete functions, simple operation, strong anti-interference ability, and a high protection level. Suitable for installation in harsh industrial environments, it is widely used in metallurgy, grain, sand yards, mining, cement, and other industries.
- Wall-mounted, waterproof, and dustproof aluminum alloy enclosure.
- 128×64 dot matrix 7-color backlit LCD display screen, English/Chinese display.
- It uses a unique anti-vibration filtering algorithm to ensure the accuracy and fast response of weighing in a vibration environment.
- It has automatic encryption, key encryption, key decryption, digital setting, digital calibration, and interface testing functions.
- Automatic tare (automatic zero tracking), speed calibration, and belt length calibration functions.
- It has a fast and stable PID quantitative batching control function.
- It can control the start and stop of the feeder and belt weigher through DI&DO switches.
- Rich and complete peripheral interfaces, and the interface functions [AO/DI/DO] can be defined for easy user operation.
- Different communication interfaces are available, supporting multiple communication protocols.
- Production data for the past year can be queried and printed by shift/day/month.
