  • 國產替代標桿:四方光電超聲波燃氣表模組助力行業升級

    2025-05-30 燃氣計量行業的挑戰與機遇在燃氣計量領域,進口品牌超聲波燃氣表模組長期占據市場主導地位。然而,隨著《計量發展規劃(2021-2035年)》政策的推動,燃氣表行業年均15%的智能化升級需求,為國產模組創造了廣闊的市場空間。四方光電憑借二十余年氣體傳感技術積累,推出了V4版本超聲波燃氣表模組,為客戶提供了兼具高精度與低成本的國產化替代方案。技術創新:國產模組的核心競爭力1.完全兼容,無縫替換在硬件適配方面,四方光電超聲波燃氣表模組的電氣接口、機械尺寸與行業主流模組一致,真正實現“即...
  • NDIR光譜技術可檢測甲烷丙烷:守護家用燃氣安全

    2025-05-30 隨著我國城鎮化進程的加速推進,天然氣(以甲烷為主要成分)和液化石油氣(以丙烷為主要成分)已廣泛應用于城鄉家庭。然而,燃氣安全事故卻時有發生,給家庭安全帶來了嚴重威脅。家用燃氣報警器作為守護家庭安全的必需品,其傳感器需要滿足家庭廚房對高精度、長壽命、低成本的嚴苛要求,以有效預防燃氣泄漏事故的發生。一、NDIR吸收光譜技術:家用燃氣安全監測的優解吸收光譜法的核心原理基于朗伯-比爾定律(Beer-Lambert),通過測量氣體分子對特定波長光的吸收程度來實現氣體檢測,具備精度高、響...
  • 四方光電超聲波燃氣表核心模塊:突破技術壁壘,國產化進程

    2025-05-20 近年來,我國天然氣的消費量的持續提升、階梯氣價政策的推行、信息技術進步,以及燃氣運營商對燃氣表智慧化管理服務水平需求的提升,燃氣表市場規模持續擴大。燃氣表的技術水平不斷提高,經歷了濕式燃氣計量表、膜式燃氣表和智能燃氣表發展的階段。近年來,智能燃氣表憑借其安全、可靠、功耗低、使用便捷、計量精準等優勢,逐漸成為燃氣表市場中應用需求增長速度的產品。超聲波計量技術是燃氣表行業未來技術發展發向之一,超聲波計量技術通過安裝于氣體流向上下游的一對超聲波傳感器發射、接收超聲波,利用超聲波信號...
  • 基于NDIR技術的A2L/A3制冷劑泄漏監測傳感器

    2025-05-20 在范圍內,面對氣候變化和雙碳目標的推進,歐洲和美國已經出臺了禁止高GWP制冷劑的政策。2023年10月6日,美國環境保護署(EPA)宣布了根據兩黨美國創新與制造(AIM)法案逐步減少破壞氣候的氫氟碳化物(HFC)的行動;此外,歐盟于2024年1月19日通過立法,進一步規范含氟氣體的排放,并計劃在2050年前實現HFC類化合物的“零投放”。這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。因此,檢測暖通空調和其他相關應用中的A2...
  • 車內缺氧隱患:被忽視的二氧化碳濃度監測

    2025-05-20 在長途駕駛過程中,很多車主都曾經歷過這樣的困擾:關閉車窗長時間駕駛后,逐漸感到困倦、注意力渙散,甚至出現頭痛等癥狀。傳統認知往往將這些現象簡單歸咎于“車內缺氧”,但真正的元兇其實是不斷累積的二氧化碳(CO2)。相較于室內環境,車內空間更為狹小密閉,CO2濃度的上升速度更快,對行車安全的影響更為直接且嚴重。缺氧的本質:CO2的“隱形攻擊”科學研究表明,在標準大氣壓下,車艙內的氣體變化具有特殊性。空氣中氧氣的正常含量是21%,對人體產生影響的臨界值為19.5%,低于臨界值人體易呼...
  • 一氧化碳傳感器:為安全保駕護航

    2025-05-20 在科技迅猛發展的今天,種類繁多的傳感器為我們的生活和工作環境提供著的監測與守護。其中,一氧化碳傳感器憑借其出色的性能和廣泛的應用,已成為保障安全的重要力量。一氧化碳是一種無色無味且毒性的氣體,其產生范圍頗為廣泛。人體若吸入過多一氧化碳,就會陷入深度昏迷,濃度越大時間越長,后果愈發嚴重,甚至可能導致死亡。正因如此,一氧化碳傳感器的應用場景豐富多元。1)住宅與商用一氧化碳檢測儀一氧化碳檢測儀中的傳感器發揮著至關重要的作用。它能實時監測空氣中一氧化碳的濃度,為人們的生活與工作筑牢安...
  • 免校準、長壽命,NMP氣體泄漏報警器開啟高效安全新時代

    2025-05-20 在鋰電池生產過程中,NMP(N-甲基吡咯烷酮)作為一種重要的溶劑,被廣泛用于溶解PVDF(聚偏氟乙烯)等粘結劑,以制備正極漿料。然而,NMP具有腐蝕性,對生產設備和鋰電池性能會造成影響,需要通過烘烤工藝將其去除,通過實時監測NMP濃度優化涂布、烘干等工藝流程,既能監控產品質量,也可保證生產過程的穩定性。同時,NMP易燃易爆,當濃度超出爆炸極,易引發安全事故。由此可見,檢測NMP濃度直接影響著電池性能、設備健康和生命安全。同時,從鋰電池生產中90%以上的NMP可回收的經濟效益,...
