Digital hopper-balance checker

Abstract

The invention discloses a digital hopper-balance checker which has rapid and accurate check and stable signals. The digital hopper-balance checker comprises a high-precision hydraulic pump, a jack, a stress bearing head and a weighing sensor of a checked hopper balance. The digital hopper-balance checker is characterized in that a plurality of digital weighing sensors are vertically arranged between the stress bearing head and the weighing sensor of a checked hopper balance and connected into a digital connecting box together. The digital connecting box transmits a digital signal into the computer to be processed by a bus. Because the digital signal can be stably transmitted and processed, compared with the prior analog sensor checker, and based on the high efficiency of rapid check, the invention can guarantee the safety and the reliability of signal transmitting and receiving and has wide market prospect.

Description

technical field [0001] The invention relates to the field of measurement and detection, in particular to a digital calibration device for industrial batching and weighing hopper scales. Background technique [0002] For the calibration of hopper scales, especially for large-capacity hopper scales or substitutes, the traditional calibration method is to calibrate with weights, but this traditional method wastes a lot of manpower, material resources and time during the loading, unloading and adjustment of weights , Generally, each scale calibration takes 2 to 3 hours. When the hopper scale is put into operation after the preliminary verification, due to the cumbersome and time-consuming verification process, which conflicts with the tense production rhythm, it is rarely re-calibrated. Due to the long-term operation, it is difficult to ensure the measurement accuracy, which affects the production process control and cost. Accounting has a greater impact. But now the main sele...

Problems solved by technology

The work efficiency is 10-40 times higher than the traditional method, and the labor intensity of workers is greatly reduced. However, the analog sensor used for comparison is easily affected by the external environment, and the anti-interference ability is weak, which is not convenient for transmission, reception and data processing.

Moreover, it is not easy to monitor the force status of each sensor of the hopper scale, resulting in inconvenient angle adjustment
