| 压电式变送器是利用正压电效应研制出来的,正高压电效应就是将一定的外力作用于电解质使其发生变形,电解质内部会出现极化现象,并且在其两个表面会产生正负不同的电荷,外力停止作用时，电解质又恢复到不带电的状况。电荷的极性会跟着作用力方向的改变而改变。在电解质极性方向施加电场，电解质也会发生变形，撤销后电解质的形变消失，这就是逆压电效应。 Piezoelectric transmitter is developed by using the positive piezoelectric effect. The positive and high voltage effect is to deform the electrolyte by applying certain external force on it, and the polarization phenomenon will occur inside the electrolyte, and different positive and negative charges will be generated on the two surfaces of the electrolyte. When the external force stops, the electrolyte will return to the uncharged state. The polarity of the charge changes with the direction of the force. When an electric field is applied in the direction of the polarity of the electrolyte, the electrolyte will also deform, and the deformation of the electrolyte disappears after cancellation, which is called the reverse piezoelectric effect. |
