拉壓力傳感器又叫電阻應(yīng)變式傳感器，隸屬于稱(chēng)重傳感器系列，是一種將物理信號(hào)轉(zhuǎn)變?yōu)榭蓽y(cè)量的電信號(hào)輸出的裝置。廣泛運(yùn)用在工業(yè)稱(chēng)重系統(tǒng)、平臺(tái)秤、電子秤、吊鉤秤、配料秤等測(cè)力場(chǎng)合。

美國(guó)Transducer Techniques LBM系列壓式力傳感器是以彈性體為中介，通過(guò)力作用在帖傳感器兩邊的電阻應(yīng)片使它的阻值發(fā)生變化，再經(jīng)過(guò)相應(yīng)的電路轉(zhuǎn)換為電的信號(hào)，從而實(shí)現(xiàn)后面的控制。它的優(yōu)點(diǎn)是精度高，測(cè)量范圍廣,壽命長(zhǎng),結(jié)構(gòu)簡(jiǎn)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(chēng)重傳感器適應(yīng)于安裝空間受限的壓式應(yīng)用，其負(fù)載按鈕可以直接用同類(lèi)型的按鈕更換，螺栓樣式在工業(yè)上運(yùn)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(cè)量更精準(zhǔn)。傳感器地步設(shè)有8個(gè)螺紋安裝孔，使傳感器安裝更為穩(wěn)固。機(jī)身為熱處理17-4ph不銹鋼設(shè)計(jì)，感應(yīng)元件結(jié)合了水準(zhǔn)的粘貼箔式應(yīng)變計(jì)，其封裝設(shè)計(jì)使得傳感器適應(yīng)絕大多數(shù)的工業(yè)環(huán)境。
