AMSTEL offers Weigh Feeders to feed bulk solids continuously to the process In a Weigh Feeder, product is fed as a continuous band onto a conveyor belt, through an inlet slide gate or automatic pre-feeder. Load cells under the belt continuously measures the weight of the product over a defined length of belt. The Weigh Feeders are suitable for installation in industrialized environment with light & heavy duty conditions respectively. They are specifically designed to provide dependable service with minimum maintenance and care. Heavy duty, Long life components are selected to assure a stable and distortion free compact assembly capable of withstanding tough industrial conditions.High quality measurement and control electronics allow both convenient operation and extensive monitoring, assuring high accuracies of feed. Weigh Feeders are able to control in continuous mode, the flow of the discharged material maintaining the instantaneous flow rate constant with respect to the set rate. The weight is measured directly at the weighing zone sensed by a centrally placed weighing idler which is placed on two numbers of high precision load cells. A digital tachometer detector generates the signal in proportion to the speed of the belt. The AMSTEL DATAWEIGH series controller continuously compares the actual weight with the set point weight, and automatically adjusts the motor speed to either increase or decrease belt speed, in order to maintain a constant feed rate. Any variation in the density of the material is reflected as a change in belt loading, which is compensated for by adjusting the belt speed

Application The AMSTEL Torpedo Weighing Rail Scale is a pit less state of the art static weighing scale for hot torpedo cars. High precision , hightemperature load cells are installed between the existing rail clamps and the existing wooden or concrete sleepers. They reliably transmit all vertical forces applied by the torpedo car wheels , with a high degree of accuracy and repeatability. The weighing system is installed without a foundation and can be installed without additional effort during a normal track maintenance period.A PC is used to record and process the weights including supplementary data Load cells determine the weight of the pig iron that is leaving the blast furnace for the steel plant. The torpedo weight can be measured.

• as a static weighing system at the tapping position of the blast furnace.
• by weighing half of the entire torpedo car.

Features

• Static weighing of hot torpedo cars.
• High temperature load cells for operating temperatures up to + 200C.
• Load cell design based on existing rails.
• Precise determination of hot metal output.
• Pitless and gap free design.
• Large measuring area.
• High accuracy.
• Installation without foundation.
• Capacities up to 800 tons.

A BELT WEIGHER is a piece of industrial equipment used to gauge the mass or flow rate of material travailing over a troughed (cupped) conveyor belt of any length which is able to adequately contain the material being weighed.

Commonly incorporated into conveyor belt systems, belt weighers are used in a wide range of industries to report instantaneous flow rate and totalised mass feed rate of powders and bulk solid materials. This data is commonly used for stock control, process control and in bulk material handling processes.

The coil scales are designed to weigh coils loaded either by crane or lift truck. Scales can be designed into existing production lines or as self contained scales

Application The AWC Dynamic (In-Motion) Axle Weighbridge is designed to be an economical and convenient solution for measuring the weight of moving trucks.The AWC JUMBO Dynamic (In-Motion) Axle Weighbridge is a system consisting of individual weighing platforms which measure the load on each wheel of a dumper truck dynamically or statically. Its modular design enables any possible truck axle configuration or model of mining dumper truck. A large external LED display is available for quick and easy viewing of the weights. A traffic light can be used with the large display to tell the driver when to move on and off the weighbridge.

• Special filtering algorithm for ensuring weighing stability and accuracy when there is strong vibration on the load receptor, and rapid response capability when the weight signal changes.
• With the multitasking mode, the weighing and control process will not be interrupted by parameter setting and the other operations.
• Once the internal temperature exceeds 45C, the cooling fan of weighing controller will work automatically to avoid overheating under the high ambient temperature.
• Optional RFID reader with Tags and traffic lights.

The platform consists of I-beams for trouble free operations year after year. Depending on the space available , both pit type and pit less designs are available. The digital load cells are pre-calibrated at full load capacity to prevent manual labour required to lift and place standard weights for cornering and calibration. This allows for an installation time of less than 8 hours and helps shorten project lead tim

Double ended shear beam load cells

AMSTEL Top Fill Pail Filler provide a reliable and quick way to fill non-foamy products. The model T-5 is designed to provide accurate liquid filling of upto 50 kg pails.

Application:
The high temperature load cells have a compensated working temperature range of +200C and a limit temperature range of +250C. They are manufactured using special strain gauges, adhesive , wiring and teflon cable to withstand the high temperature. This makes then suitable for weighing systems for tundish , ladle transfer cars , ladle turrets , ladle cranes , foundry cranes etc and other applications that are subject to intense heat.
Load cells can also be offered having the same body style and capacities as ABB and Schenck load cells replacing capacities from 10MT to 160MT.
