  • 告別冷媒泄漏隱患:冷媒安全一站式解決方案

    2025-05-20 近期,四方光電冷媒泄漏監測傳感器獲得UL的正式認可,成為獲得此項認證的亞太地區傳感器企業。這一重要成果彰顯了四方光電在產品質量和安全方面的追求,為空調制造商提供了符合UL認證的一站式解決方案,以應對日益嚴格的制冷劑監管環境。面對氣候變化和雙碳目標的推進促使暖通空調及制冷(HVACR)行業向低GWP制冷劑的轉型,然而,低GWP制冷劑存在使用安全風險,這就要求設備需配備高效、可靠的冷媒泄漏監測系統,以確保產品使用安全。四方光電基于綜合的傳感器技術平臺和技術創新,已經形成了包括空調...
  • 國產替代正當其時,四方光電柴油發動機氮氧傳感器技術突破

    2025-05-20 隨著汽車數量激增,尾氣污染已成為大氣環境的主要威脅。柴油車排放的氮氧化物(NOx)和顆粒物(PM)不僅危害人體健康,還會加劇溫室效應、破壞臭氧層。為應對這一挑戰,國家實施了最嚴的國六排放標準——2023年7月全面推行的國六b標準,將氮氧化物排放限值大幅降低41.7%,嚴控至每公里35毫克。柴油車尾氣處理的核心技術是“顆粒捕捉器(DPF)+選擇性催化還原裝置(SCR)”的組合。其中,SCR系統如同“凈化器”,通過噴射尿素將有毒的氮氧化物轉化為無害的氮氣和水。而這一過程的關鍵便是...
  • 【技術原理】電化學技術

    2025-05-20 空氣中的甲醛氣體分子通過透氣膜進入到傳感器,發生氧化及還原反應從而形成電子的轉移,電子的正向移動形成電流,由此產生的電流信號由經過放大后輸出,電流的大小與空氣中的甲醛含量成正比。為了消除干擾氣體對甲醛檢測的影響,四方光電深入研究甲醛電極片反應原理及化學組分,采用雙膜片方案來進行選擇性測量,解決了其他氣體(酒精)對甲醛傳感器測量的干擾。同時,根據空氣凈化器、新風系統的運行狀態數據,結合需要考慮的運行場景進行多傳感器信息融合,以輸出準確的甲醛濃度數值。
  • 標準市場:四方光電參編《便攜式甲醛檢測儀》團體標準

    2025-05-20 為規范行業發展,確保消費者利益,由中國空氣凈化行業聯盟發起、中國質量檢驗協會批準的《便攜式甲醛檢測儀》(T/CAQI140—2020)團體標準于2021年2月6日實施。基于多年電化學甲醛氣體傳感技術的研發及較早產業化的客戶端配套經驗,四方光電股份有限公司受邀參與了此次《便攜式甲醛檢測儀》標準的編制。標準適用于室內空氣質量測試用便攜式甲醛檢測儀,不適用于在腐蝕性和爆炸性氣體特殊環境場所。其中,針對消費者比較關注的便攜式甲醛檢測儀的檢測性能按檢測精度進行了A/B/C三個等級的劃分...
  • 四方光電激光光譜技術的十年布局,助推氣體分析儀器國產化提速

    2025-05-20 在臺激光器誕生60多年后的今天,隨著激光光源、探測技術、實驗裝置和數據處理等各方面技術的飛躍發展,激光光譜技術作為微觀感知領域的核心技術,已經成為物理、化學、生物、環境以及天文學等領域中研究光與物質相互作用的重要手段,從實驗室基礎研究到各領域應用線都扮演著的角色。拉曼光譜技術早有布局,突破工業過程氣體分析技術瓶頸在工業過程氣體監測領域,傅里葉紅外(FITR)、質譜(MS)、氣相色譜(GC)等原理的氣體分析儀各有優點。傅里葉紅外技術一個氣室很難適合不同的量程,也無法分析H2、0...
  • 四方光電冷媒泄漏監測傳感器榮獲UL認證

    2025-05-20 近期,四方光電冷媒泄漏監測傳感器AM4203RM-R454B和AM4203RM-R454C在UL(UnderwritersLaboratories)北美實驗室順利通過了UL60335-2-40/CSAC22.2No.60335-2-40家用和類似用途電器的安全熱泵、空調器和除濕機的特殊要求附錄LL的測試,獲得UL的正式認可,成為獲得此項認證的中國傳感器企業。這一重要成果彰顯了四方光電在產品質量和安全方面的追求,為空調制造商提供了符合UL認證的一站式解決方案,以應對日益嚴格的制...
  • 防患于未“燃”,四方光電激光甲烷傳感器助力燃氣安全保障

    2025-05-20 燃氣行業安全現狀燃氣行業作為城市生命線之一,關系民生和社會經濟運行,截至2022年底,全國城市燃氣普及率為98.05%。隨著其廣泛應用,燃氣安全的風險也日益凸顯。基于當前我國燃氣安全現狀,2023年8月安全生產委員會印發《全國城鎮燃氣安全專項整治工作方案》,要求全鏈條整治城鎮燃氣安全風險隱患,推進城市生命線安全工程建設。燃氣安全問題分析導致燃氣事故發生的原因錯綜復雜,包括管網老化泄漏、企業生產經營不規范、燃氣具不合標等。我國城市燃氣管道多處于地下環境中,地下環境錯綜復雜,管道...
  • 四方光電粉塵傳感器,深耕技術行業發展

    2025-05-20 近日,國外咨詢機構YoleIntelligence發布報告《GasandParticlesensors2024》,報告對氣體和粉塵傳感器市場進行了調研,分析了氣體和粉塵傳感器的市場現狀、具體的細分市場和未來發展趨勢,報告顯示氣體和粉塵傳感器市場在2023年至2029年間增長8%,到2029年市場總規模將達到約28億美元,在消費、工業、汽車和醫療這4大領域都有所增長。圖1氣體和粉塵傳感器的市場預測報告中提及的粉塵傳感器是一種用于監測環境中粉塵顆粒濃度的裝置,它通過使用光學、電子...
