Small Single Point Load Cell 3kg Single Point Weight Transducer 5kg
High Accuracy Single Point Load Cell FNK is a strain gauge based weight transducer which offers 0-3kg / 0-5kg / 0-10kg / 0-15kg / 0-20kg five rated measuring ranges to choose from. High accuracy weighing sensor FNK delivers maximum 0.02% non-linearity of the full capacity. Off center load cell FNK is corner trimmed for platform sizes up to 200x200mm which makes it suitable for off-center load measurement. Weight Transducer FNK delivers stable performance within the declared working temperature range thanks to its temperature compensation process. Load sensor FNK utilizes strain gauges with 1000 ohms resistance to reduce power consumption, it is designed with 2xM5 threaded holes on each end for easy installation. You may find Load Cell Transducer FNK suitable for applications such as packaging machines, counting scales, feeding machines, force simulators, vending machines and so on.

A weight sensor is a transducer that converts mechanical load into electrical signal which is proportional to the load being applied.The measured load or force causes deformation of the measuring element(elastic body),the bonded strain gauge deforms accordingly which will cause the resistance change of the wheatstone bridge,under constant power supply, the output signal between Sig+ and Sig- will change proportionally, thus the load/force can be measured by measuring the output signal from the load cell which is normally within 0-30mV for Weight Transducer FNK. Overloading is the most common cause of loadcell failure, a load sensor is just like a spring in certain aspects, which will be damaged if overstretched or overloaded. A machanical stop(refer to below picture) can be used to protect the sensor from excessive deformation. The deformation gap can be determined by loading the sensor with rated capacity, then adjust the meachnical stop to reach the bottom of the transducer. In most cases, the load cell will be used to measure load at 40-80% of the full capacity, thus the deformation distance can be adjusted using reference load a bit higher than the target load to be measured instead of the rated capacity.
