Precise Weighing for Efficient Solid Feedstock Introduction

Accurate weight measurement is crucial for economic and trouble-free plant operation in solid feedstock dosing in modern biogas plants. Especially in solid feedstock introduction, the feeding of fermenters, and the dosing of substrates such as silage, manure, or solids, reliable and durable weighing technology is essential.

Our proven weighing system consists of the following components:

• GTI load cell
• MK-GTI mounting module
• WWB junction box
• WWA-1 display unit
• optional WWD-3 remote display

This system was specially developed for the high demands of solid feeders, substrate feeders, dosing containers, and other applications in the biogas industry.

Why a GTI double shear beam load cell is the ideal solution for solid feeders

The GTI load cell is a high-quality double shear beam load cell (also known as a double-ended shear beam load cell) and impresses with its exceptional stability and measurement accuracy.

High measurement accuracy even under difficult conditions

Due to the symmetrical design and central force application, the load is distributed evenly. This results in particularly precise and reproducible measurement results.

Advantages:

• High accuracy with changing loads
• Stable readings even under harsh operating conditions
• Optimal weight detection for automatic feeding of biogas plants

Resistant to shocks, vibrations, and side forces

Significant loads often act on a solid feeder. During filling, the following regularly occur:

• lateral forces
• vibrations
• shocks from above
• torques

The GTI load cell was developed precisely for these requirements. Side forces and vibrations have only a minimal effect on the measurement result and simultaneously protect the weighing technology from damage.

Extreme load capacity for heavy loads

The load cells are designed for high load capacities and are available in the following weighing ranges:

• 5,000 kg
• 10,000 kg
• 20,000 kg
• 30,000 kg
• 50,000 kg
• 75,000 kg
• 100,000 kg

In addition, each load cell has an overload reserve of 150% without damage occurring.

For most solid feeders and dosing containers in biogas plants, we recommend the versions with 10,000 kg or 20,000 kg nominal load.

Stainless steel design for maximum lifespan

The GTI load cell is made of high-quality stainless steel and offers:

• hermetically sealed design
• laser-welded housing
• protection class IP68
• calibratable version according to Class C3
• highest corrosion resistance

Optionally, we supply the load cells with a stainless steel protective hose against rodent damage, which is a great advantage especially in agricultural applications.

MK-GTI Mounting Module – secure installation and easy service

The suitable MK-GTI mounting module ensures professional and secure integration of the load cells under the solid feeder.

Advantages of the MK-GTI mounting module

• made of robust galvanized steel
• integrated lift-off protection
• integrated overload protection
• easy maintenance
• quick replacement of defective load cells

A particular advantage: Should a load cell ever need to be replaced, this can be done with an empty container without using a jack.

Individual adapter plates for every solid feeder

Not every hole pattern fits a mounting module as standard. Therefore, we manufacture individual adapter plates for attaching the feeder feet to the load cells upon request.

This way, you receive a customized solution for your system.

Flexible systems from 4 to 12 load cells

Depending on the size of the solid feeder, we supply complete weighing systems with:

• 4 load cells
• 6 load cells
• 8 load cells
• 10 load cells
• 12 load cells

This allows reliable weighing of both small dosing containers and large solid feedstock introductions.

The right WWB junction box for every application

For reliable signal transmission from the load cells, we use our WWB series junction boxes. Depending on the number of load cells used and the requirements of the system, versions made of plastic, aluminum, or stainless steel are available.

In systems with more than 8 load cells, several junction boxes can be coupled together.

WWA-1 Display Unit – the intelligent control center of your weighing system

The WWA-1 display unit processes the weighing data and enables easy integration into existing plant controls.

Robust design for continuous use

Thanks to protection class IP66/IP68, the WWA-1 is optimally protected against:

• dust
• moisture
• water
• dirt

and designed for continuous use in agricultural operations.

Flexible and easy-to-read display

The integrated display offers:

• resolution of 48 x 16 pixels
• 10 brightness levels
• single or dual-line display
• optimal readability under all conditions

Various interfaces for plant integration

The WWA-1 has numerous communication options:

• analog outputs
• bus systems
• control interfaces
• remote display connection

This allows the weighing system to be easily integrated into the control system of your biogas plant, feeding system, or dosing technology.

High-precision processing of weighing signals

The WWA-1 enables:

• direct connection of up to 4 load cells
• connection of up to 16 load cells via junction boxes
• fast and precise weight measurement
• reliable process monitoring

Optional WWD-3 Remote Display for optimal readability

For convenient display of current weight values, we recommend the WWD-3 remote display.

Advantages of the WWD-3

• stable aluminum housing
• protection class IP66/IP68
• 56 mm digit height
• 5-digit display
• excellent readability even from a greater distance

Especially in large systems, the remote display allows for quick checking of weight and fill level values.

Conclusion: The professional weighing solution for solid feeders in biogas plants

Anyone looking for a reliable, durable, and highly precise solution for weighing solid feeders, substrate feeders, or solid feedstock introductions will find a perfectly coordinated complete system with the interaction of GTI load cells, MK-GTI mounting modules, WWB junction boxes, WWA-1 display unit, and the optional WWD-3 remote display.

The combination of high measurement accuracy, extreme load capacity, easy maintenance, and optimal integration into existing control systems makes this weighing system the ideal solution for modern biogas plants.
