用途：用于測(cè)量混凝土試件在一定環(huán)境條件下，硬化過程中長(zhǎng)度（體積）發(fā)生變化的專用儀器，可為建筑科學(xué)研究院所、教育部門、設(shè)計(jì)和施工單位對(duì)砊的特性進(jìn)行研究、教育、質(zhì)量控制和檢測(cè)提供可靠依據(jù)。
執(zhí)行標(biāo)準(zhǔn)：
GB/T50082-2009《普通混凝土長(zhǎng)期性能和耐久性能試驗(yàn)方法標(biāo)準(zhǔn)》
現(xiàn)有臥式混凝土收縮膨脹儀存在如下不足：
（1）標(biāo)準(zhǔn)中校準(zhǔn)桿材質(zhì)建議選擇硬鋼或石英玻璃材質(zhì)制作，但目前市場(chǎng)上的校準(zhǔn)桿基本上都為不銹鋼材質(zhì)，不銹鋼校準(zhǔn)桿的線膨脹系數(shù)很大，易因溫度波動(dòng)影響造成誤差。
（2）千分表精度差，即使選用業(yè)內(nèi)較好的電子千分表也有±3um的測(cè)量誤差，一般的千分表誤差在±5um以上，這對(duì)于混凝土試件后期收縮量本來(lái)就很小而言，會(huì)造成很大的誤差。
（3）試驗(yàn)過程人工讀數(shù)記錄，易因人為筆誤或在數(shù)據(jù)抄寫過程中失誤造成錯(cuò)誤。
并且，由于在整個(gè)試驗(yàn)周期中，同一個(gè)試件要測(cè)量十幾次，上述3種誤差因素會(huì)被不斷放大，很有可能出現(xiàn)前后試驗(yàn)結(jié)果相互矛盾的現(xiàn)象，且無(wú)法找到問題根源。
The shortcomings of available horizontal concrete shrinkage expansion meter:
(1) Hard steel or quartz glass is recommended for the calibration rod material in the standard, but the available calibration rod in the market is mostly made of stainless steel. Its linear expansion coefficient is too high, which is easy to cause errors due to the influence of temperature fluctuation.
(2) The accuracy of the micrometer is poor, even if the best electronic micrometer is used, because its measurement error is more than 3um. Generally, the error of the micrometer is more than 5um, which will cause a great error for the shrinkage of concrete specimens in the later period.
(3) Manual reading records during the test process are prone to errors, which is caused by human errors or errors in data transcription.
Moreover, the same specimen needs to be measured more than a dozen times in the whole test cycle. The above error factors will be enlarged continuously, and it is likely that there will be conflicting phenomena between early and later results. We can’t find the root cause of the problem.
技術(shù)特點(diǎn)：
1、測(cè)量準(zhǔn)確：高精度位移傳感器配合無(wú)膨脹合金校準(zhǔn)桿使用，測(cè)量誤差在±1um以內(nèi)，，保證了長(zhǎng)齡期測(cè)試結(jié)果的準(zhǔn)確性和對(duì)比性；
2、無(wú)需長(zhǎng)期在線觀測(cè)，到達(dá)齡期后測(cè)試即可，提升了設(shè)備使用效率；
3、試驗(yàn)過程無(wú)需手動(dòng)記錄，全部數(shù)據(jù)存儲(chǔ)于測(cè)試主機(jī)當(dāng)中，試驗(yàn)人員通過U盤即可將試驗(yàn)結(jié)果導(dǎo)出，然后通過電腦excel軟件查看即可；
4、測(cè)試結(jié)果自帶操作人員標(biāo)識(shí)，同時(shí)記錄試驗(yàn)時(shí)間、試驗(yàn)環(huán)境的溫濕度、試件編號(hào)、齡期、試件長(zhǎng)度；
5、設(shè)備具有權(quán)限設(shè)置功能，非操作人員無(wú)法登錄，保證了試驗(yàn)結(jié)果的安全性；
Features:
1. More accurate: With the help of high-precision displacement sensor and invar calibration rod, the measurement error is less than 1um, which ensures the accuracy and comparability of long-term test results.
2. No needs for long-term on-line observation. Testing at the age can improve the efficiency of the equipment.
3. There is no need to record manually during the test process. All the data are stored in the test host. All results could be derived by the user through U disk, and then can be viewed by Excel.
4. The test results are marked by operators, and the test time, temperature and humidity of the test environment, specimen number, age and length are recorded at the same time.
5. The device has the function of permission setting, and the non-operator can not log in, which ensures the safety of the test results.
