拉壓力傳感器又叫電阻應變式傳感器，隸屬于稱重傳感器系列，是一種將物理信號轉變為可測量的電信號輸出的裝置。廣泛運用在工業稱重系統、平臺秤、電子秤、吊鉤秤、配料秤等測力場合。

美國Transducer Techniques LBM系列壓式力傳感器是以彈性體為中介，通過力作用在帖傳感器兩邊的電阻應片使它的阻值發生變化，再經過相應的電路轉換為電的信號，從而實現后面的控制。它的優點是精度高，測量范圍廣,壽命長,結構簡單，頻響特性好。

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紐扣式稱重傳感器適應于安裝空間受限的壓式應用，其負載按鈕可以直接用同類型的按鈕更換，螺栓樣式在工業上運用很多。傳感器表面平滑，直徑至少2英寸，外徑微微凸起，更利于承受力均勻分配，測量更精準。傳感器地步設有8個螺紋安裝孔，使傳感器安裝更為穩固。機身為熱處理17-4ph不銹鋼設計，感應元件結合了水準的粘貼箔式應變計，其封裝設計使得傳感器適應絕大多數的工業環境。
