Load Cell

What is Load Cell?

The load cell is a force transducer that converts the force into electrical parameters. The main categories are

        • Pneumatic
        • Hydraulic
        • Strain gauge
        • Capacitance

Pneumatic: The pneumatic load cells is used in the force-balance principle. This principle is a force is applied to one side of a diaphragm and an air pressure is applied to the other side.

Hydraulic: When a force is applied on a fluid medium contained in a bound space, the pressure of the fluid increments. This expansion in the pressure of the fluid is relative to the applied power. Henceforth a measure of the pressure in the weight of the fluid turns into a proportion of the applied power when adjusted.

Strain gauge: This load cells converts the load acting on them into electrical signals.  Strain gauge load cells are widely using load cells for different applications.

Types of strain gauge load cells

Based on the configuration of the number of active elements in the Wheatstone bridge

There are mainly 3 categories

      • Quarter
      • Half
      • Full Bridge

The force-balance principle utilizes additionally in pneumatic load cells. The shape is directly proportional to the electrical resistance. The main advantage of these load cells is versatile, high accurate, and cost-effective.

They add all temperatures and conditions, and since it’s not a mechanism, if the chamber ruptures no fluids will leak to contaminate the actual environment. to work effectively, pneumatic load cell require clean, dry, regulated air or nitrogen.


Common types of load cell

Load cell are classified on the basis of load detection, precision, and also the general purpose. These are different  types of load cells:

      • Bending beam: To monitor force  act on the sensing element when the spring element  causes elastic deformation
      • Load Button: When the load is placing in one single point or button.
      • Single Point Load Cell: most common applications from small to medium loads.
      • Pancake: Both tension or compression measurements single point shear beam: Low capacity compact weighing systems up to about 5 tons
      • Double-ended shear beam: spring element fixed at both ends and loaded in the center.
      • S-type: used for general purpose measurements like both compression and tension.
      • Miniature: This type is fit for the applications where less space and capacity load cell

Advantages of Load cell:


      • Inherently explosion-proof
      • Insensitive to temperature variations
      • They don’t contain fluids, therefore, there’s no possibility of contamination of the method if the diaphragm breaks.
      • Less expensive so mostly utilized in the industry

Load cell are often required for varied load-bearing applications, both for ensuring the safety of individuals & the environment and for maintaining structural integrity. Other applications like Food & Beverage Industries, Sensor for Robotic Surgery, Food & Beverage Industries, Bridge & Dam Structure Stress Monitoring, etc. To know more about the top & best load cell manufacturers in India visit sensomaticloadcell.com.
