Ecomatik植物莖流監(jiān)測(cè)系統(tǒng)

系統(tǒng)功能

SF-G探針式莖流傳感器是用來(lái)連續(xù)測(cè)量樹(shù)干中莖流速率的儀器。

工作原理

將兩個(gè)探針插入樹(shù)干，給處于上部的探針用恒定能量加熱，上下二個(gè)探針之間的溫度差反應(yīng)樹(shù)干中的莖流速率，用經(jīng)驗(yàn)公式換算成莖流速率。

系統(tǒng)特點(diǎn)

適合于直徑大于2厘米的樹(shù)干；

傳感器可重復(fù)使用。

缺點(diǎn)：

樹(shù)干縱向溫度變化（±2.5℃）和測(cè)量結(jié)果疊加，導(dǎo)致測(cè)量錯(cuò)誤可能超過(guò)99%；

無(wú)法測(cè)量夜間液流。夜間液流人為的假設(shè)為零。
