Page 8: Operating Principle
TY-KH15-009A Ver. 3 6/ 10 Operating principle The pressure receiving part of this product is a diaphragm which converts pressure into strain. The amount of the strain is detected by the semiconductor strain gauge. The detection circuit is the full bridge type whose four sides consist of semiconductor strain gauge. From this bridge circuit, electric signals proportional to the strain are obtained. -
