熒光法葉綠素在線傳感 器 我有新說法
756 0

【BK-S15S】，博科儀器品質(zhì)護(hù)航，客戶至上服務(wù)貼心。熒光法葉綠素在線傳感器是一種用于實(shí)時(shí)監(jiān)測(cè)水體中葉綠素濃度的先j設(shè)備。該傳感器基于葉綠素分子在特定波長(zhǎng)光照射下產(chǎn)生熒光的原理，通過測(cè)量熒光強(qiáng)度來推算葉綠素含量。

　　一、簡(jiǎn)介

　　【BK-S15S】，博科儀器品質(zhì)護(hù)航，客戶至上服務(wù)貼心。熒光法葉綠素在線傳感器是一種用于實(shí)時(shí)監(jiān)測(cè)水體中葉綠素濃度的先j設(shè)備。該傳感器基于葉綠素分子在特定波長(zhǎng)光照射下產(chǎn)生熒光的原理，通過測(cè)量熒光強(qiáng)度來推算葉綠素含量。其核心部件包括激發(fā)光源、熒光探測(cè)器和信號(hào)處理單元。傳感器通常采用藍(lán)光或紅光作為激發(fā)光源，能夠快速、準(zhǔn)確地反映水體中浮游植物的生物量，廣泛應(yīng)用于湖泊、河流、海洋等水環(huán)境的監(jiān)測(cè)。

　　二、優(yōu)勢(shì)

　　高靈敏度與實(shí)時(shí)性：熒光法葉綠素在線傳感器能夠檢測(cè)到極低濃度的葉綠素，響應(yīng)時(shí)間短，可實(shí)現(xiàn)連續(xù)在線監(jiān)測(cè)，及時(shí)反映水體中浮游植物的動(dòng)態(tài)變化。

　　無(wú)需試劑，環(huán)保高效：與傳統(tǒng)化學(xué)分析方法相比，該傳感器無(wú)需添加化學(xué)試劑，避免了二次污染，同時(shí)降低了運(yùn)行成本。

　　抗干擾能力強(qiáng)：通過優(yōu)化光學(xué)設(shè)計(jì)和算法，傳感器能夠有效排除水體中懸浮物和其他色素的干擾，提高測(cè)量精度。

　　易于集成與維護(hù)：傳感器結(jié)構(gòu)緊湊，可與其他水質(zhì)監(jiān)測(cè)設(shè)備集成，支持遠(yuǎn)程數(shù)據(jù)傳輸和自動(dòng)化控制，維護(hù)簡(jiǎn)單，適合長(zhǎng)期部署。

　　三、工作原理

　　在線葉綠素傳感器是一種專門用來檢測(cè)葉綠素含量的設(shè)備，它的工作原理基于葉綠素的熒光特性和吸光特性。

　　在自然光或特定波長(zhǎng)的光源照射下，葉綠素會(huì)吸收光能并發(fā)出熒光。這種熒光的強(qiáng)度與葉綠素的含量成正比，因此可以通過檢測(cè)熒光的強(qiáng)度來估計(jì)葉綠素的含量。

　　在線葉綠素傳感器的優(yōu)點(diǎn)是可以實(shí)時(shí)、快速、無(wú)損地測(cè)量葉綠素含量，可用于河流、湖泊、池塘、海洋調(diào)查、養(yǎng)殖業(yè)、飲用水源、藻類和浮游植物狀況的研究、調(diào)查和監(jiān)測(cè)。

　　四、維護(hù)和保養(yǎng)

　　1.維護(hù)日程

　　維護(hù)項(xiàng)目維護(hù)時(shí)間備注

　　清洗傳感器0.5～3天（無(wú)刷）4～8周（有刷）

　　傳感器檢查6個(gè)月

　　更換O型圈1～2年

　　2.保養(yǎng)方法

　　1）傳感器外表面檢查，用清水沖洗傳感器的外表面，如果仍有污垢殘留，請(qǐng)用濕潤(rùn)的軟布進(jìn)行擦拭，對(duì)于一些頑固的污垢，可以在水中加入一些家用洗滌液來清洗。

　　2）傳感器線纜檢查，檢查線纜外皮是否存在斷裂，正常工作時(shí)線纜不應(yīng)緊繃。

　　3）測(cè)量窗口檢查，檢查是否有臟污，用無(wú)塵布進(jìn)行擦拭。

　　4）傳感器校準(zhǔn)可通過上位機(jī)軟件校準(zhǔn)，也可以通過自已通過

　　RS-485發(fā)送MODBUS指令自行校準(zhǔn)。

　　3.傳感器校準(zhǔn)

　　3.1零點(diǎn)校準(zhǔn)

　　用棕色燒杯量取適量蒸餾水，將傳感器垂直放在溶液中，傳感器前端離燒杯底部至少10cm，3～5分鐘待數(shù)值穩(wěn)定后進(jìn)行零點(diǎn)校準(zhǔn)。

　　3.2斜率校準(zhǔn)

　　將傳感器放置于標(biāo)準(zhǔn)溶液中，傳感器前端離燒杯底部至少10cm，3～5分鐘待數(shù)值穩(wěn)定后進(jìn)行斜率校準(zhǔn)。
