Dosing devices / loss-in-weight feeders
A loss-in-weight feeder is a specialized measuring device used in industry to dose and weigh materials with high precision. This type of scale is commonly used in industries such as food processing, pharmaceuticals, chemicals and other areas where accurate weight measurements are critical to production. The principle of the loss-in-weight feeder is based on the continuous weight measurement of the material to be dosed during the production process. In contrast to conventional scales, which measure a static weight, a loss-in-weight feeder is designed to measure and regulate the weight of a continuous flow of material. A key feature of the loss-in-weight feeder is its ability to take very accurate measurements. This is achieved by using high-precision sensors that can detect even the smallest changes in weight. This accuracy is particularly important in processes where compliance with precise recipes or formulations is required. Another important aspect of the loss-in-weight feeder is its ability to integrate into automated systems. Many of these scales can be connected to control systems that automatically adjust the material flow based on the measured weights. This enables very efficient and precise control of the dosing process. In summary, a loss-in-weight feeder is a high-precision instrument used in various industries for the accurate dosing and weight measurement of materials. Its ability to measure and control continuous material flows makes it an indispensable tool in many modern manufacturing processes.
Control system for loss in weight feeder (DE-CONx)
The DE-CONx dosing control supports the operation of differential feeder when dosing bulk materials and powders using dosing screws, vibrating chutes, belts, etc. Thanks to the continuous performance determination and evaluation, automatic performance adjustment can be made at any time. Highlights: • Regulates the setpoint-precise dosing according to the "loss in weight" principle in a continuous process • Supports the gravimetric and volumetric operation of differential feeders when dosing bulk materials and powders • Highly precise dosing due to adaptive control • Optimized refill handling • Integrated control of a conveyor system (option) • Automatic scale adjustment • Speed monitoring of the discharge device (digital / analog) • Continuous performance determination and evaluation for automatic performance adjustment in start-up and shut-down operation • Single and batch operation • Time-related throughput counter • Control of additional components for product activation (screws, knockers) and dust prevention (filters, suction) Features: • Digital filtering of the weight values (digital/analog recording) for an exact calculation of the conveying capacity • High-resolution weight value recording via digital/analog load cells • Direct connection of load cells (4/6-wire technology) • Serial/analog control of the frequency converter • Internal alarm memory • Integrated web server for complete configuration and parameterization • Can be used as a DIN rail device in the control cabinet or directly in the system • 4 digital inputs and outputs with a range of standard functions (release, operating contact, external fault, refill process, alarm, etc.) can be assigned or are available for free use
Weighing electronics (DE-CONscale/DE-CONloadcell)
Weighing electronics for strain gauges and digital load cells The electronics of the DE-CONscale detects the measurement signal from up to 4 strain gauge load cells or digital load cells, generates highly accurate weight values by means of parameterizable hardware and software filters and is ideally suited for operation with almost any PLC system.

HMIs/ Panels
Operating terminals for all dosing controllers in the DE-CON family, as well as a variety of other machine controls. Perfect for operating individual components or for diagnostic and maintenance purposes. Highlights • Robust construction in protection class IP65 for use under difficult production conditions • Reliable and low-maintenance thanks to fanless design • Compact and handy design makes it suitable for use on site or in the control cabinet • Communication via Ethernet-based or serial interface • Extensive range of interfaces for communication at different levels • 100% compatible with Congrav OP1-S and all Congrav control systems from Brabender Technologie
Vibratory feeder
The DE-DDW-VF60 is a compact, high-quality dosing system for the precise gravimetric dosing of free-flowing bulk materials in the low to medium throughput range. The system combines a vibration-optimized discharge chute with a near-resonance, energy-efficient drive for consistent material flow during operation. Weight measurement is performed via a strain gauge load cell, enabling highly accurate and reproducible dosing. Thanks to its robust construction and industrial-grade materials, the VF60 is ideally suited for production environments with high demands on process stability, measurement accuracy, and easy integration into existing systems.
