埋入式应变计：是一种用于测量材料内部应变的传感器，它被嵌入或埋入到结构或材料内部。通过在材料内部放置应变计，可以实时测量材料的应力和应变变化，并评估结构或材料的性能和安全性。数据采集系统用于接收、放大、滤波和记录传输的信号。它可以是一台数据采集仪、数据记录器或计算机等设备，负责将应变计的信号转换为可读取和分析的数据。
振弦式表面应变计：是表面应变计的一种类型，它采用振弦这种弹性材料作为传感器元件，通过弦的振动来测量物体表面的应变.通常由振弦、电缆、信号调节器等组成。振弦是一种薄的弹性金属丝，通常由铜、硬合金或钨等材料制成。当物体表面受到应变时，振弦发生弯曲和扭转等形变，从而影响其震动状态。电缆连接振弦和信号调节器，并将振弦的振动信号传输到信号调节器中。信号调节器对信号进行放大、滤波和转换等处理，得到表面应
表面应变计：是一种用于测量材料或结构表面的应变(变形)的传感器。它可地测量材料或结构表面受力后的应变变化，以评估其在受载情况下的性能和安全性。通常由应变片、应变导线和信号调节器组成。应变片是一种非常薄的传感器，可以附着在测量目标表面，例如金属、混凝土等。应变感应片的形状和材质会随着具体的应用而有所不同。
