Importance of Contact Thickness Gauges 

Contact thickness gauges play an essential role in various industrial sectors, particularly in the steel and aluminum industries. These gauges are used to measure the thickness of materials with high accuracy, ensuring that the final products meet specific standards and requirements. Accurate thickness measurement is crucial for maintaining product quality, as deviations can lead to material waste, structural weaknesses, and overall product failure. 
In the steel and aluminum industries maintaining precise thickness is vital for ensuring the structural integrity and performance of the end products. Whether it’s in automotive manufacturing, aerospace, or construction, the precision offered by contact thickness gauges helps in achieving the desired material properties and performance characteristics. 

Common Challenges in Using Contact Thickness Gauges 

Despite their importance, several challenges can affect the accuracy and reliability of contact thickness gauges: 
  1. Calibration Issues: 
  • Regular calibration is essential to maintain the accuracy of thickness gauges. Inconsistent calibration can lead to erroneous measurements, affecting the quality of the final product. 
  1. Environmental Factors: 
  • Industrial environments can be harsh, with extreme temperatures, dust, and vibrations. These factors can impact the performance of the gauges, leading to inaccurate readings. 
  1. Material Variations: 
  • Different materials have varying properties, such as hardness and elasticity. These variations can affect the interaction between the gauge and the material, potentially leading to measurement errors. 
  1. Wear and Tear: 
  • Continuous use in industrial settings can lead to wear and tear of the contact points, which can degrade the gauge’s performance over time. 

Solutions to Maintain Precision 

To address these challenges and maintain the precision of contact thickness gauges, the following solutions can be implemented: 
Regular Maintenance and Calibration: 
  • Implementing a routine maintenance schedule is crucial. Regular calibration ensures that the gauges provide accurate readings. Using calibration standards and reference materials can help in maintaining consistency.   
Environmental Controls: 
  • Protecting gauges from harsh environmental conditions is essential. Using protective enclosures and implementing environmental control systems can mitigate the impact of dust, temperature fluctuations, and vibrations. 
Advanced Sensor Technology: 
  • Employing advanced sensor technologies that are less susceptible to environmental factors can enhance accuracy. For instance, upgrade the analogue sensors from 20 MUBE/20 MOBE to digital sensors type 20 MUB-DIG-805 / 20 MUB-DIG-812  in combination with Vollmer VTS  
    ( Vollmer Toch Screen) that do not require any regular calibration, only checking to fulfil ISO standard. This will give a better resolution and signal processing capabilities that will improve the long term measurement precision. 
Material-Specific Adjustments: 
  • Customizing the measurement process based on the specific material properties can help in achieving accurate results. This may involve adjusting the contact force via the VTS ( Vollmer Touch Screen ) or using specialized measuring diamonds designed for specific materials. 
Regular Inspections and Replacements: 
  • Conducting regular inspections to check for wear and tear of the contact points is important. Replacing worn-out components promptly can prevent degradation in performance. 


Contact thickness gauges are indispensable tools in industrial quality control, offering the precision needed to ensure product consistency and performance. Addressing common challenges through regular maintenance, environmental controls, advanced technologies, and material-specific adjustments can significantly enhance the accuracy and reliability of these gauges. By implementing these solutions, industries can optimize their production processes, reduce material waste, and maintain high standards of quality.
