Why Use a Load Pin for Force Measurement?

 
 
 

Direct Mechanical Integration

 
A load pin can replace a conventional mechanical pin in many applications. This enables force measurement directly at the load-bearing joint without requiring a completely separate load cell installation.
 
 
 

Compact Installation

 
Because the sensing element is integrated into the pin, load pins are particularly useful where installation space is limited.
    
     
 
 
 

Real-Time Load Monitoring

 
Load pins can provide continuous load information for safety monitoring, overload protection, process control, force measurement and load indication.
     
   
 
 
 

Customizable Mechanical Design

 
Unlike many standard load cells, load pins can be manufactured around the dimensions of an existing mechanical structure. This makes them particularly suitable for OEM machinery and custom equipment.
 
 
 

Suitable for Demanding Applications

 
Depending on the selected material, sealing and electrical configuration, load pins can be developed for industrial, outdoor, marine and other demanding applications.

From Your Drawing to a Custom Load Pin

Need a Custom Load Pin?

Send us your application information, existing pin drawing or required specifications.
Our engineering team can help evaluate the appropriate load pin design for your equipment.

Quality, Testing & Calibration

Reliable force measurement depends on more than the strain gauge itself. Mechanical design, machining accuracy, strain gauge installation, temperature compensation, sealing, wiring and calibration all influence the final performance of a load pin.

Calibration Support

Each load pin can be tested under controlled loading conditions according to the applicable product specification. Calibration documentation can be provided where required.

Custom Testing Requirements

If your project has special testing requirements, please provide the relevant technical specification during the quotation stage.

Load Pin FAQs

  • Q What is a load pin?

    A A load pin is a force sensor designed in the form of a mechanical pin. Strain gauges are incorporated into the pin so that forces passing through the pin can be measured while the component continues to function as part of the mechanical structure.
  • Q What is the difference between a load pin and a load cell?

    A A load pin is a type of load cell specifically designed to function as a pin or axle within a mechanical joint. Traditional load cells are often mounted as separate measuring components, while load pins can replace an existing mechanical pin and measure force directly at the joint.
  • Q Can you manufacture a load pin according to my existing pin dimensions?

    A Yes. Custom load pins can be developed according to an existing pin drawing or physical dimensions. Please provide the pin diameter, overall length, mounting features, required capacity and application information.
  • Q What information is required for a custom load pin quotation?

    A We recommend providing pin drawing, rated capacity, pin diameter, overall length, loading direction, application, output signal, cable requirements, operating environment and quantity. If some information is unavailable, our engineering team can help evaluate the application.
  • Q What output signals are available for load pins?

    A Depending on the model and project requirements, output options may include mV/V, 0–10V, 4–20mA, RS485, CAN / CANopen and wireless. Please confirm the required signal during the quotation stage.
  • Q Can load pins be made from stainless steel?

    A Yes, stainless steel options can be considered for applications requiring improved corrosion resistance. Material selection depends on rated capacity, dimensions, mechanical strength and operating environment.
  • Q Can load pins be used in marine or offshore applications?

    A Yes, load pins can be designed for selected marine and offshore applications. The appropriate material, protection level, sealing method, cable and connector should be selected according to the actual environment.
  • Q Can you manufacture IP67 or IP68 load pins?

    A Environmental protection requirements can be considered during the custom design process. Please specify whether the load pin will be exposed to rain, humidity, dust, temporary immersion or continuous underwater operation.
  • Q How do I choose the correct load pin capacity?

    A The load pin capacity should be selected according to the maximum working load, dynamic loading, possible overload conditions and the safety factor required by the machine or application. We recommend providing both the normal operating load and maximum possible load when requesting a quotation.
  • Q Can a load pin replace an existing mechanical pin?

    A In many applications, yes. This is one of the main advantages of a load pin. However, the mechanical structure, loading direction, bearing surfaces and available strain measurement area should be evaluated before the replacement is designed.
  • Q Do you provide customized load pin drawings?

    A For custom projects, technical drawings can be prepared according to the confirmed requirements and reviewed before production.
  • Q Do you provide calibration for load pins?

    A Calibration and testing can be provided according to the load pin model and project requirements. Contact us if you require specific calibration documentation.
