FSD high-precision electronic belt scale
The FSD series electronic belt scale is a dynamic measuring product composed of advanced microcomputer controlled dynamic weighing instruments. It is an ideal equipment for continuous measurement of bulk materials in belt conveyor systems. The overall design is reasonable and compact, with complete mathematical models for weighing and control, and multiple input and output signal forms. It has a simple structure, accurate weighing, stable operation, reliable operation, convenient operation, and low maintenance. It is not only suitable for conventional environments, but also for acid, alkali, salt, and atmospheric corrosive environments. Widely used in metallurgy, power, mining, ports, chemical industry, cement, building materials, grain and other industries.
Performance Characteristics
High-precision
The weighing structure and components have broken through the inherent technology, and the actual usage accuracy has exceeded 0.2%, far higher than the market average level, and can be maintained for a long time. Adapt to various on-site uses, especially in trade situations that require precise settlement.
Stable operation
Selected materials and precision components, produced with lean technology, using a direct load-bearing scale frame, no lever pivot, no movable parts, and no problems such as pivot wear and rubber aging, ensuring continuous and stable operation.
Easy operate
Convenient transportation and installation, with minimal maintenance in the later stages; Remote monitoring, timely troubleshooting, and one click remote operation. The horizontal surface is small, with less dust accumulation, and does not require frequent cleaning. Daily use basically eliminates maintenance troubles.
Strong adaptability
Widely used in industries such as metallurgy, power, mining, grain, and trade settlement that require high-precision measurement, it is waterproof, dustproof, and corrosion-resistant. In addition to conventional environments, it can be applied to various harsh environments such as acid and alkali.
Product Composition
FSD high-precision scale frame
Modular combination technology has fewer power transmission links and is easy to install. Unique mechanical structure (with patented technology), invisibly variable, zero stability. The fully suspended structure has no ear pivot points and requires minimal maintenance of movable parts.
Touch screen weighing instrument
The belt scale instrument adopts 32-bit 180MHz high-speed operation processing to ensure stable operation and calculation accuracy, and a 16 bit DA converter ensures more accurate 4-20mA output. This machine has a large capacity storage space, and its storage capacity can be queried for daily/monthly historical data storage and query functions. The data storage adopts FLASH mode, which can automatically save various process data when the system is powered off. After powering on again, the system will continue to run on the data.
Digital weighing sensor
The independently developed industrial grade digital second-generation weighing sensor enhances the dynamic digital filtering function and adds linear compensation function on the basis of the original generation digital sensor. It overcomes the disadvantages of traditional sensors such as small output signal, short transmission distance, and poor anti-interference ability, making the data during dynamic weighing more authentic, stable, and reliable.
Speed encoder
The double-sided rubber coating effectively prevents the belt from slipping, and the carbon steel shell has good mechanical strength, shielding and sealing properties suitable for outdoor installation. The brushless DC pulse generator does not require adjustment, calibration or maintenance, and the coaxial connection structure more effectively ensures speed measurement accuracy and greatly improves the service life of the equipment.
Working Principle
-
Generate signal
The weighing bridge is installed on the conveyor frame. When the material passes by, the measuring roller detects the weight of the material on the belt conveyor and acts on the weighing sensor through a lever, generating a voltage signal proportional to the belt load.
-
Speed calculation
The speed sensor is directly connected to the large-diameter speed measuring drum, providing a series of pulses, each pulse representing a belt movement unit, and the frequency of the pulses is proportional to the belt speed.
-
Calculation results
The weighing instrument receives signals from the weighing sensor and speed sensor, integrates them to obtain an instantaneous flow rate value and a cumulative weight value, and displays them separately.
