Product description: The EACCOR-B160 belt scale calibration device series provides various calibration methods suitable for all on-site situations, from ordinary hanging codes to all calibration equipment for large physical static scales, truly achieving market mechanism based and comprehensive customer service.

Overview

The EACCOR-B162 verification chain code consists of a series of evenly weighted rollers and their connecting devices. When the belt is running, the rollers rotate in place on the belt, and the weight of the chain code can simulate the force of the material balance system. By calculating the corresponding theoretical weight and comparing it with the displayed value of the belt scale, the calibration of the belt scale can be achieved. This calibration method is closer to the state of physical operation, and combined with the material coefficient of the Qijie belt scale used, it can replace physical verification.

elaborate on

The B162 belt scale chain code verification device is a device for verifying electronic belts installed on belt conveyors. It is widely used in situations where electronic belt scales are used to measure bulk materials in power, metallurgy, chemical industry, docks, building materials, coal mines, and other fields. To achieve automatic verification of the accuracy of electronic belt scales, usually used for verifying various types of electronic belt scales with accuracy levels between 0.5 and 2.0.

The manual chain code verification device for the B162 belt scale conforms to the provisions of the National Metrological Verification Regulations of the People's Republic of China (JJG195-2002). It is a simulated load standard device that can more conveniently calibrate and correct the measurement accuracy of electronic belt scales. When in use, connect the standard weight chain code into a whole chain, cross the effective length of the scale area, and place it above the calibrated electronic belt scale, with both ends fixed. The B160 series verification chain code assembly is convenient, reliable, and easy to handle.

Working principle: after the electronic belt scale is zeroed, when the rolling weight of standard weight runs on the belt, Dynamic simulation the material state, and transfer the weight to the weighing sensor through the scale body. At the same time, the speed sensor transmits the pulse voltage signal to the integrator, which performs calculations and performs automatic interval verification.

This verification system can also choose an automatic winding device, and the entire chain code is lowered and wound by an electric winch, which is more convenient, simple, and labor-saving. The B163 electric winch chain code verification device is installed on the upper part of the electronic belt scale, above the conveyor at the body of the electronic belt scale. When verifying the electronic belt scale, this device can automatically and smoothly place the chain code on the belt scale body, completing the accuracy verification of the electronic belt scale. There are two forms to choose from for retracting and releasing chain codes: winch or horizontal.

The calculation formula for chain code selection: chain code kg/m K=maximum flow rate Q ÷ coefficient 3.6 ÷ V belt speed × (50% to 100%)

Note: Q is measured in tonnage and V is measured in meters per second.

The B164 winch type is driven by a motor reducer to drive the winding drum, and the chain code is automatically retracted and released by an electronic control device.
The B163 box type chain code is stored in the box, which is usually stored in the box when not in use. When in use, it is operated by an electronic control device to automatically place the chain code on the belt above the scale body.
According to the above conditions, a reasonable calibration method should be selected considering the actual use site.
