Hopper scales are suitable for hoppers of various shapes, such as square hoppers, round hoppers and inclined hoppers. The material can be liquid or granular solid. Hopper scales have mechanical, hydraulic and electronic types, among which electronic hopper scales are widely used. The picture shows the working principle of a typical electronic hopper scale. The force sensor is installed under the hopper, usually 3 or 4 high capacity load cells are used. After the weight of the material acts on the force sensor, it is converted into an electrical signal and amplified by the amplifier in the measuring circuit for display, recording and data processing. The new electronic hopper scale can weigh gross weight, tare weight and net weight, with automatic zero adjustment and weighing data processing functions. Electronic hopper scales are widely used in automatic batching weighing systems. Weighing instrument for measuring the weight of material in a hopper.

LDC hopper scale overview:

The LDC series electronic hopper scale is an ideal modern automatic weighing equipment for bulk materials. Mainly divided into accumulative hopper scales and loss-in-weight feeding scales. The accumulative hopper scale is especially suitable for non-viscous bulk material trade measurement because of its higher weighing accuracy of load cell sensor than the continuous accumulative automatic weighing instrument. industry use.

According to the control method, it can be divided into accumulative hopper scale and loss-in-weight hopper scale.

LDC-L accumulative hopper scale divides a batch of materials into discrete load sequences and weighs each weight value and then accumulates it to obtain the accumulated total weight. It has the advantages of static scale and high weighing accuracy.

LDC-S loss-in-weight hopper scale (continuous static hopper scale): the feeding device controls the feeding amount according to the process requirements, the controller compares the "loss-in-weight value" negotiated in each unit time with the set value, and automatically adjusts according to the deviation Feeding quantity, thus ensuring the accuracy of continuous weighing and feeding.

Hopper scale system composition:

The hopper scale is composed of storage hopper, weighing hopper, unloading device,

shear beam sensor, control system, weighing display system and other mechanisms.

Static metering or dynamic loss-in-weight feeding, metering and feeding precision converted from static metering.

It can be connected with the upper computer management system.

It can be controlled by NH series instrument, PLC or industrial computer.
