Verification method for belt scale

Time:7/6/2023  From:EACCOR

With the widespread application of electronic belt scales in bulk material transportation measurement operations, the calibration problem of electronic belt scales is also receiving increasing attention from users. After all, the accuracy of measurement accuracy is related to the accuracy of enterprise cost control and data accounting. Below, we will briefly introduce several common calibration methods for electronic belt scales.

Method 1: The physical calibration device for the hopper scale is currently a highly accurate calibration method, mainly suitable for situations with wide working space and high precision requirements. The working principle is also relatively simple. The weight of the experimental material is measured by two hopper scales, and then the experimental material is sent to the conveyor belt of the electronic belt scale that needs to be calibrated. The calibration is carried out by comparing the weighing data. However, the disadvantages of high device cost and large space requirement are also obvious, and the system itself may have certain deviations. When the deviation is greater than 0.1%, it requires frequent self calibration.

 

Method 2: Chain code verification

It is generally divided into winch chain code device and cyclic chain code device. Its working principle is to lay the standard chain code flat on the belt, and when running the belt, the roller rotates with the belt to simulate the material running state. The data obtained through the algorithm is compared with the actual weight of the standard chain code for verification. The difference is that the winch chain code device is located at the head of the belt. When not in use, the chain code can be drawn into the device and released when in use. The cyclic chain code device is located above the belt and is set as a cyclic closed loop. When in use, the chain code is placed flat on the belt and can be retracted when not in use. Chain code verification has high accuracy, occupies less space, and is relatively low-cost. The disadvantages are: 1. High installation requirements for the scale; 2. Unable to simulate material operation perfectly, inaccurate; 3. The cyclic chain code has high vibration, is prone to wear and tear, and is prone to deviation. The actual verification deviation is between 1% and 10%.

 

 

Method 3: Hanging Code Verification

Hanging code verification device is a device that suspends standard weight weights on the belt scale roller or weighing bridge, simulating the weight data of materials during operation. The cost of hanging code verification is low and the device is convenient. However, if the belt scale structure has poor resistance to tension changes and relatively low accuracy, it is suitable for small space and low precision requirements in work situations.

 

 

The above calibration methods are time-consuming and labor-intensive, and cannot guarantee accuracy. Is there a simple and accurate calibration method?

Xuzhou Yike Electric Co., Ltd. high-precision intelligent control matrix belt scale can achieve self calibration, maintenance free, while ensuring high accuracy and stability.

Eaccor's eight to sixteen modular scale bodies can be mutually verified and redundant, while matrix modular scale bodies can all adopt electric automatic code hanging verification without the need for manual labor. Modular scales can be used in sequence intervals, and combined with matrix intelligent weighing instruments, they are divided into two sets of scales within the system.

The ECO fully intelligent matrix scale achieves high stability and precision while truly solving two fundamental problems with belt scales: 1. knowing when the scale is inaccurate, and 2. real-time online automatic correction of accuracy.

No matter the matrix scale is in the no-load or loaded state, as long as the intelligent matrix instrument judges that individual weighing units of the system are out of tolerance, it can automatically conduct real-time automatic mutual calibration. The internal intelligent data model of the instrument will lift the electric weight device of the matrix scale unit at intervals, and automatically correct the instantaneous amount and Cumulant of the rated weight, so that the matrix scale system will always maintain a stable operation in a high-precision state, truly achieving the maintenance free matrix scale, Fully automatic self inspection and high-precision operation without manual interference.
