Load MeasurementBolt / Force Measurement Bolt / Measurement Axis

Force Transducers, Series: MA

5 kN … 100 kN

Load pins are force transducers, which are used in fork bearings. They replace simple bolts. Upper and lower part of a construction are often linked by load pins. That’s the reason why they are appropriate for load measurement. Thanks to the huge spreading of fork bearings in the machine and plant construction the load pin is a type of force transducer which is used many times. The advantage is that there is no additional design change necessary.

"Heavy Duty" Load Measurement Bolt
Measurement Bolt / Force Measurement Bolt / Measurement Axis

Load Cells, Series: MAH

50 kN … 500 kN

The “Heavy Duty” measurement axes are specifically designed for use in very harsh and demanding environmental conditions, such as outdoors or in cranes. To this end, in this corrosion-resistant and high-strength stainless steel version, the sensor elements are protected by laser-welded covers, and the amplifier electronics—including the connector—are fully integrated into the measuring axis.

Introduction to Gauge Pins

What are measuring pins / force measuring pins / load measuring pins / measuring axes?

Measuring bolts—also known as force-measuring bolts, load-measuring bolts, or measuring shafts—are force sensors used to measure forces and loads in mechanical systems. They are installed in place of conventional bolts or shafts and enable reliable force monitoring in numerous industrial applications.

Applications and Areas of Use

Force measurement bolts and measurement axes are used in cranes, conveyor systems, mechanical engineering, and the automotive industry. They measure forces to monitor and optimize processes, enhance safety, and improve efficiency in demanding environments such as offshore platforms or heavy industry.

Benefits of Force Measurement Technology in Industry

Force measurement technology enables the monitoring of loads, protects against overloads, and optimizes processes. It enhances safety, reduces costs through early fault detection, and enables efficient machine control—making it indispensable for modern industrial operations.

How Measurement Pins Work

How does a measuring pin work?

A load cell measures the forces acting on it. Strain gauges integrated into the load cell respond to even the slightest deformations caused by loading. These deformations are converted into electrical signals, which are then used to determine the forces acting on the load cell. The data can be analyzed in real time to monitor machines, optimize processes, and ensure safety.

Signal Conversion and Data Transmission

Load cells convert mechanical deformations into electrical signals using strain gauges. These signals are amplified, digitized, and transmitted to control systems or monitoring software. This precise transmission enables real-time monitoring and optimizes control processes in industrial applications.

How are measuring pins integrated into mechanical systems?

Measuring bolts are installed directly into existing mechanical systems by replacing conventional bolts. They measure forces directly at the source, without the need for additional sensors or modifications. This simple integration saves space, simplifies installation, and provides reliable measurement data for monitoring and control.

Where are measuring pins used in industry?

Load cells are used in industry in cranes, conveyor systems, and production lines. They measure loads and forces to prevent overloads and ensure operational safety. In automation, they help optimize processes by providing precise data for control and monitoring.

What role do survey stakes play in the construction industry?

In the construction industry, load cells measure forces in load-bearing structures such as construction cranes. They monitor loads in real time and detect critical conditions early on.

How are measuring studs used in the automotive industry?

In the automotive industry, load-measuring bolts are used to analyze stresses in vehicle components such as axles or suspensions. This enables better design and testing for improved performance and reliability.

FAQ

Frequently asked questions

What is a measuring pin, and how does it work?

Load cells are bolt-shaped or cylindrical sensors that replace conventional bolts in mechanical systems and measure forces by detecting deformations using integrated strain gauges. These deformations are converted into electrical signals, which are used for force monitoring and process optimization.

Load cells measure tensile, compressive, or combined forces and, depending on the model, are designed for different measurement ranges—from small forces in laboratory applications to high loads in heavy industry. As bipolar sensors, they can measure both tensile and compressive forces and can be adjusted, depending on the application, to measure a single force direction or both. For special requirements, X/Y load cells are also available, which measure forces in multiple directions and even enable measurements in the four directions ±Fx and ±Fy. These load cells are used, for example, in the aerospace industry, on the parachutes of an escape capsule.

They are suitable for many environments, including harsh conditions such as offshore facilities, high temperatures, or humid environments. Special materials and protection ratings make them robust and durable.

Yes, there are custom-made products that can be adapted to specific requirements, such as unique installation situations, measurement ranges, or environmental conditions.

Sensor bolts replace conventional bolts and are installed in existing systems. They require proper alignment and wiring; wireless models eliminate the need for wiring.

Accuracy depends on the type and quality; most models achieve accuracies in the range of 1–2% of the final value.

Load cells require an evaluation unit or a data acquisition system that processes the electrical signals and displays or stores them as force values.

Regular inspections and calibrations ensure accuracy. In harsh environments, bolts should be checked for wear or damage.

Yes, the measuring pins are designed and manufactured in accordance with all relevant standards, specifications, and guidelines. These include:

  • Machinery Regulation (EU) 2023/1230
  • EMC Directive 2014/30/EU
  • RoHS Directive 2011/65/EU
  • Regulation (EU) 2024/2847, EU Cyber Resilience Act (EU CRA)

The relevant declarations of conformity are available.
