固體密度計(jì)是將現(xiàn)代微電子技術(shù)與阿基米德原理相結(jié)合而研發(fā)出來(lái)的新型密度測(cè)試儀器。此儀器改變了傳統(tǒng)密度測(cè)試的繁瑣操作，實(shí)現(xiàn)了橡粉末粉塵、膠固體、塑料固體、精密陶瓷、磁性材料等固體樣品的快速測(cè)量。該新型固體密度計(jì)能滿(mǎn)足現(xiàn)代產(chǎn)品生產(chǎn)及新材料研究過(guò)程中對(duì)樣品密度的測(cè)量要求。
固體密度計(jì)的設(shè)計(jì)原理：
固體密度計(jì)是通過(guò)浮力與密度計(jì)算公式的推導(dǎo)與變換形成等式，首先利用高精密固體分析天平分別計(jì)算出待測(cè)樣品在空氣中的重量(W1)和在水中之重量(W2)，并計(jì)算出W1-W2值，水的密度默認(rèn)為ρ=1，通過(guò)V樣品=V排水建立等式，即可計(jì)算出樣品的密度值：ρ=W1/(W1-W2)xρ水，此為固體計(jì)算公式。如果待測(cè)樣品為液體，則先利用一個(gè)已知體積和密度的標(biāo)準(zhǔn)塊作為參考物，通過(guò)水的密度ρ水與標(biāo)準(zhǔn)塊在空氣中重量(W1)水中重量(W2)得出計(jì)算公式：ρ液=(W1-W2)/標(biāo)準(zhǔn)塊V xρ標(biāo)準(zhǔn)
固體密度計(jì)的功能：
1、快速檢測(cè)，更有效率；
2、具有實(shí)際水溫補(bǔ)償功能，可適應(yīng)測(cè)試環(huán)境變化；
3、采用一體成型大容量專(zhuān)業(yè)測(cè)量平臺(tái)，高透明，耐磨耐摔；
5、配置一體成型防風(fēng)防塵罩，組合方便，堅(jiān)固耐用；
6、具有全自動(dòng)零點(diǎn)追蹤、蜂鳴器報(bào)警、超載報(bào)警功能；
7、具有溶液補(bǔ)償功能，使用時(shí)做戒指，也可以使用其他液體介質(zhì)；
8、具有密度上下線(xiàn)設(shè)定功能，可自動(dòng)判斷式樣是否合格，并報(bào)警提示。
