Load Cell CZL 601 40KG

A load cell transducer/sensor generates an electrical signal whose magnitude is directly proportional to the force measured. The standard straight bar load cell 40kg (sometimes called a strain gauge) translates up to 40 kg of pressure (force) into an electrical signal. Each load cell 40kg measures the electrical resistance that changes is proportional to the strain (e.g. pressure or force) applied to the bar. The output of the load cell is in milli-volts and cannot be directly measured by a micro-controller. So an ADC with high resolution or an instrumentation amplifier reads the output of the load cell to the microcontroller.

The intensity of deformity defines how much force is applied, and this value is digitally sent to an interface module. This gauge can determine how heavy an object is, whether the object’s weight changes over time or if you simply need to sense the object by measuring strain or load applied to a surface. This straight bar load cell is made from an aluminium alloy. And it is capable of reading a capacity of 40KG of weight. These load cells also provide an IP65 protection rating for the sensor.

Here each load cell consists of four strain gauges connected into a Wheatstone bridge. Wheatstone bridge is basically two potential dividers connected in parallel. Here SG1 and SG2 form one of the potential divider circuits. Similarly, SG3 and SG4 form the other divider circuit. Output voltage for the load cell taken from the midpoint of the potential divider circuits. Therefore, when strain is applied to the bridge, the gauge measures the strain as an electrical signal, because the strain changes the electrical resistance of the wire.
