All piezoelectric materials also have a distinct pyroelectric effect. This describes the change in the electric polarization of ferroelectric materials as a result of a change in temperature. This effect is undesirable since it often leads to charge separations in the oscillation measurement. These arise from the change in temperature and not through the mechanical vibrations occurring in the measured object.
However, this effect can be limited due to the design. The interferences are grouped together in the interference transfer factor for temperature changes.
所有压电材料也具有明显的热释电效应。这描述了由于温度变化而导致铁电材料电极化的变化。这种效应是不希望的，因为它通常会导致振动测量中的电荷分离。这些是由温度变化引起的，而不是通过被测物体中发生的机械振动引起的。
然而，由于设计的原因，这种影响可以被限制。在温度变化的干扰转移因子中，这些干扰被归纳在一起。
The values specified in the sensor's technical data have been determined as a step response to a change in temperature for the lower electrical limit frequency fu = 1 Hz.
Changes in temperature, in particular, cause interference in the low frequency domain below f = 10 Hz since this is generally a low frequency event.
传感器技术数据中规定的数值已被确定为对温度变化的阶梯式响应，其电气下限频率 fu = 1 Hz。
温度的变化，特别是在f = 10 Hz以下的低频域引起干扰，因为这通常是一个低频事件。
