In the field of weighing and force measurement, bellow type load cell have emerged as a critical component, offering unmatched precision and reliability. These load cells are widely used across various industries for their unique design and functionality.

What is a Bellow Type Load Cell?

A bellow type load cell is a force sensor designed to measure weight or force through deformation. It gets its name from the bellows-like structure of its housing, which enhances its flexibility and ability to handle dynamic loads. The bellow structure not only protects the internal components but also allows for precise and repeatable measurements under varying conditions.

How Does a Bellow Type Load Cell Work?

The bellow type load cell operates based on the principle of strain gauge technology. When a load or force is applied, the bellow structure deforms slightly. This deformation is captured by strain gauges bonded to the internal structure. These gauges convert mechanical deformation into electrical signals, which are then processed to determine the exact weight or force.

The bellow housing plays a crucial role in protecting the strain gauges from environmental factors such as dust, moisture, and vibration, ensuring long-term durability and accuracy.
