S type load cell is one of the most common sensor.It is mainly used for measuring strain and pressure between solids.It is aslo knowm as tension sensor.because its shape is like S,so people always call it S type load cell.The material of this load cell QH-31 can be alloy steel or stainless steel.And it adopts rubber seal production,easy to install and use,and it is suitable for electronic weighing system such as crane scale,batching scale and machine-changing scale.
Sensor is based on the principle that the elastomer (elastic element,sensitive beam) is elastically deformed under the action of external force,then the strain gauge(conversion element) attached on the surface is aslo deformed together.When resistance strain gauge is deformed,the value will change (increase or decrease).And then through the corresponding measurement circuit converts thia resistance change into an electrical signal(valtage or current),so as to complete the process of converting ecternal force into electrical signal.
