BT2-DL超聲波螺栓張力監(jiān)測(cè)器是我們螺栓產(chǎn)品的*新儀表。
簡(jiǎn)介
它融合了DAKOTA NDT BT1-DL螺栓張力監(jiān)視器的所有偉大功能,在功能、硬件、速度和長(zhǎng)度方面增加了一些好處。DAKOTA NDT BT2-DL超聲波螺栓張力監(jiān)視器非常準(zhǔn)確地測(cè)量長(zhǎng)度可達(dá)100英尺的緊固件,并在整體性能/功率方面得到更高提升!
當(dāng)螺母和螺栓在負(fù)載下緊固在一起時(shí),擰緊螺母的動(dòng)作會(huì)增加施加在螺栓上的力,從而導(dǎo)致伸長(zhǎng)。
通過(guò)使用超聲波,螺栓張力監(jiān)視器不受溫度、摩擦或電阻因素的影響,這些因素會(huì)影響標(biāo)準(zhǔn)扭矩測(cè)量技術(shù)的精度-使達(dá)科他州BT1-DL螺栓張力監(jiān)視器的精度在0.0001毫米(0.0001英寸)內(nèi)。
使用儀表的USB接口以及可選的關(guān)閉附件,可以編程為在施加適當(dāng)?shù)呢?fù)載時(shí)自動(dòng)停止擰緊過(guò)程。
