WIKA Weighing Electronics – Signal Conditioning, Processing & Display Solutions
Weighing electronics from WIKA complement load cells and force transducers to build complete weighing systems. They include amplifiers, transmitters, weighing indicators, junction boxes, and digital interfaces. These devices convert raw sensor signals into usable outputs such as 4–20 mA, 0–10 V, digital bus signals or direct display values.
With the right electronics, load cells can be precisely calibrated, monitored, diagnosed and integrated into PLC, SCADA or IIoT systems — essential for both industrial and legal-for-trade weighing applications.
FAQ About WIKA Weighing Electronics
Answers regarding functionality, selection criteria, wiring, integration and typical use cases.
What components are included in weighing electronics?
Weighing electronics typically consist of:
- Amplifiers / transmitters for load cell bridge signals
- Weighing indicators with displays
- Junction / summing boxes for multi-cell systems
- Cable and signal interfaces such as 4–20 mA, 0–10 V or digital protocols
Why is the correct choice of electronics important?
The electronics determine:
- Signal accuracy and noise immunity
- Calibration and diagnostic capabilities
- Integration with PLC, SCADA or IIoT
- Legal-for-trade suitability and compliance
Without the right electronics, even a high-quality load cell cannot deliver optimal performance.
Which output signals are typical?
Common outputs include:
- mV/V — raw bridge output from the load cell
- 4–20 mA or 0–10 V — standardized analog outputs
- Digital interfaces — CANopen®, Modbus, Profibus, Ethernet-IP and others
What should be considered during wiring and installation?
- Use shielded cables and avoid introducing mechanical stress through cabling
- Ensure proper grounding and equipotential bonding for EMC compliance
- Use SENSE lines for long cable runs to compensate for voltage drops
- Mount electronics in appropriate environmental conditions (humidity, dust, temperature)
How are multi-cell platforms connected?
For multi-load-cell systems, a summing/junction box combines the signals. It also allows corner adjustment to ensure equal response across the platform. The combined signal is then sent to the amplifier or indicator.
What are typical error sources in weighing electronics?
- Incorrect signal scaling or amplifier saturation
- Poor calibration or drift over time
- EMC interference, lightning, grounding issues or cable losses
- Using electronics not rated for the environmental conditions
Which applications require weighing electronics?
- Industrial platform and floor scales
- Tank and silo weighing with multiple load cells
- Dosing, filling and packaging systems
- Integration into PLC/SCADA/IIoT environments with real-time data
How can I request a quotation?
Please provide:
- Number and type of load cells
- Preferred output signal (analog/digital)
- Environmental conditions (IP rating, temperature, Ex-zone)
- Special requirements such as legal-for-trade use, diagnostics or fieldbus interfaces
