LCS series electronic belt scale physical detection device
LCS series of electronic belt kind detecting means is designed for electronic belt physical material detection apparatus, the apparatus is a belt scale assay of regulation process (JJG 650) and the Ministry of verification procedures JJG (power) -02 requirements, And the Metrology Office of the Ministry of Electric Power on the implementation of the electronic belt scale physical detection device construction standard assessment requirements (Dianji Hanzi 97 No. 10) and professionally equipped products. Because the equipment can perform physical calibration on the electronic belt scale from time to time, thus ensuring the dynamic accuracy of the belt scale, it can be widely used in the physical detection of electronic belt scales in the electric power, metallurgy, coal, port, chemical and other industries.

1. It adopts CC21 type and CS type dual remote control weighing sensor and EDI type weighing display controller, which are domestically leading in reliability and accuracy, especially suitable for harsh environments.
2. Using PLC programmable controller, coal is taken from the upper belt to the end of weighing, the flow control of coal caving and the vibration of the silo wall can be controlled according to the set sequence, and the degree of automation is high.
3. There is an indication of the opening degree of the material door on the control panel and the hopper door, so that the operator can see it at a glance and adjust the flow in time.
4. The weight hoist has two options: manual and automatic, and the automatic method is controlled by PLC.
5. The lower part of the hopper adopts an all-stainless steel structure to prevent coal accumulation and increase the service life of the scale body.
6. The material door is designed with a unique double-opening lining stainless steel gate, which is less prone to blocking and depositing coal than the usual radial gate structure.
7. The unique dust-proof structure makes the entire hopper device dustproof and airtight, and the environment is clean and sanitary.
