拉压力传感器又叫电阻应变式传感器，隶属于称重传感器系列，是一种将物理信号转变为可测量的电信号输出的装置。广泛运用在工业称重系统、平台秤、电子秤、吊钩秤、配料秤等测力场合。

美国Transducer Techniques LBM系列压式力传感器是以弹性体为中介，通过力作用在帖传感器两边的电阻应片使它的阻值发生变化，再经过相应的电路转换为电的信号，从而实现后面的控制。它的优点是精度高，测量范围广,寿命长,结构简单，频响特性好。

The Transducer LBM Series (Load Button) load cells are offered for compression only applications where space is limited. This load button is a direct replacement for many of the same type and bolt patterns currently used in the industry. LBM The matching surface must be flat and at least 2 inches in diameter. The loading diameter is slightly convex for accurate load distribution.

Eight threaded mounting holes are provided on the bottom surface for fastening down from beneath. These sensors are manufactured from heat treated 17-4ph stainless steel, and the sensing element incorporates bonded foil strain gages of the highest quality. They are sealed for protection against most industrial environments.

LBM纽扣式称重传感器适应于安装空间受限的压式应用，其负载按钮可以直接用同类型的按钮更换，螺栓样式在工业上运用很多。传感器表面平滑，直径至少2英寸，外径微微凸起，更利于承受力均匀分配，测量更精准。传感器地步设有8个螺纹安装孔，使传感器安装更为稳固。机身为热处理17-4ph不锈钢设计，感应元件结合了最高水准的粘贴箔式应变计，其封装设计使得传感器适应绝大多数的工业环境。
