Off-center Load Cell Transducer 5lb 10 lb 20 lb 30lb 40 lb 50 lb Weight Sensor
High Accuracy Off Center Load Cell FNG is a strain gauge based weight transducer which offers 0-6.6 lb / 0-13.2 lb / 0-22 lb / 0-33 lb / 0-44 lb / 0-66 lb / 0-88 lb seven measuring ranges to choose from. Precison Weight Sensor FNG delivers maximum 0.02% non-linearity of the full capacity. 1000 ohms high resistance strain gauges are used to reduce the power consumption, it is designed with 2xM6 threaded holes on each end, one end for mounting the sensor, the other end for loading. Loadcell FNG is corner trimmed for platform sizes up to 250x350mm which makes it suitable for off-center load measurement. Load Cell sensor FNG delivers stable performance within the declared working temperature range thanks to its temperature compensation process. You may find Load cell transducer FNG suitable for applications such as beehive weighing scales, force simulators, packaging machines, vending machines, platform scales, feeding 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 off-center loadcell FNG. 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 gap can be adjusted using reference load a bit higher than the target load to be measured instead of the rated capacity.
