Load Cell 40 Kg

A load cell is a sensor or Transducer then converts electrical signal proportional to the force applied to it.

Load cells are commonly used in weigh Scales.One of the most common type of Load Cell is Strain Gauge Type. Strain Gauge type load cells are particularly stiff, have very good resonance values, and tend to have long life cycles in application.

Strain gauge load cells work on the principle that the strain gauge (a planar resistor) deforms/stretches/contracts when the material of the load cells deforms appropriately. These values are extremely small and are relational to the stress and/or strain that the material load cell is undergoing at the time. The change in resistance of the strain gauge provides an electrical value change that is calibrated to the load placed on the load cell.

The output electrical signal generated by the load cell is in millivolts and cannot be sensed by your regular 8 bit or 12 bit ADC. Special Instrumentation amplifiers are required to amplify this low voltage signals before it can be used. Special modules based on IC's which are used in weigh scales are also available. One such module is based on HX711 24-Bit ADC Weigh Scale Module which eliminates the need for costly instrumentation Amplifiers.

We have various types of Load Cells, Force Sensor, Flex Sensor and Pressure Sensor. Check our complete collection of Load cell.
