CZL601 40 Kg Load cell for Electronic weighing scale

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.

This is a standard load cell for measuring weight upto 40 Kg. The most common use of this weight sensor is in weighing machine. Every weighing machine which shows weight has a load cell as sensing element. 

This conversion is indirect and happens in two stages. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge measures the deformation (strain) as an electrical signal, because the strain changes the effective electrical resistance of the wire. A load cell usually consists of four strain gauges in a Wheatstone bridge configuration. Load cells of one strain gauge (quarter bridge) or two strain gauges (half bridge) are also available.

The electrical signal output is typically in the order of a few millivolts and requires amplification by an instrumentation amplifier before it can be used. The output of the transducer is plugged into an algorithm to calculate the force applied to the transducer.

Load cells are used in several types of measuring instruments such as weighing scales, universal testing machines.

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