What is a Load Sensor? – Types, Features & Case Studies

A Load Sensor is a device that detects the force (including mass and torque) and converts it into an electrical signal when force is applied.

Types of Load Sensors and Their Features

There are two types of load sensors:

  • Strain-Gauge Sensor: Generally larger in size. Suitable for long-term monitoring of large forces.
  • Piezoelectric Sensor: Smaller in size and capable of high-speed measurements. However, due to its operating principle, it is prone to sensor drift.

Main Applications of Load Sensors

Load sensors are widely used across various industries. Typically:

Piezoelectric Sensors are chosen for measuring large forces.

Strain-Gauge Sensors are preferred for measuring large forces.

Applications include:

  • Mass measurement.
  • Control device in the medical field.
  • Material testing.
  • Semiconductor and electronic device testing.

Yamanaka’s Load Sensor and Case Studies

Our “PiezoBolt” is a bolt piezoelectric load sensor.
This sensor incorporates a highly sensitive piezoelectric element within the bolt, enabling it to measure changes in axial force applied to the bolt. By simply replacing existing bolts with “PiezoBolts”, you can monitor the load conditions around the bolt locations on machinery and detect changes or early signs of tiny cracks in dies.
We have selected some case studies to showcase their applications. Please take a look below.


  • Detection of Cracks in Die: This is a case study that demonstrates the detection of cracks in dies during the forging process of automotive components.

     


  • Detection of Scraps: This case study highlights the identification of small scraps during the drawing process of sheet metal.

     


  • Maintenance of Press Machine: This case study showcases the reduction of load on press machines during piercing processes.

     


  • Detection of Defects of Cutting Tool: This case study focuses on detecting defects such as breakage, wear, and deflection in cutting tools.

     


  • Detection of Abnormalities in Casting: This case study illustrates the identification of causes of porosities during aluminum die-casting production.
