<p> 壓力變送器，可進行表壓、絕壓和負壓的測量。具有精度高、穩(wěn)定性好、響應(yīng)速度快、抗干擾、耐沖等特點。膜片材質(zhì)采用316L不銹鋼，輸出信號可選擇電流型、電壓型和數(shù)字型輸出。對于石化行業(yè)來說，壓力變送器的精度是重要考量指標，壓力變送器可定制0.1高精度產(chǎn)品。除了精度，壓力變送器的穩(wěn)定性也被控制在±0.1%FS/年。石化行業(yè)較為特殊，很多場合都需要用到防爆型壓力變送器。壓力變送器有隔爆型、本安型和粉塵本安型三種不同的防爆類型，客戶可根據(jù)現(xiàn)場實際使用情況進行選擇。石化行業(yè)對壓力變送器的還有許多其它的要求，例如需要測量像原油這些帶有顆粒、沖擊大或者粘稠的介質(zhì)，這時就需要使用抗沖擊型壓力變送器，其特殊的工藝設(shè)計具有有效的抗干擾能力，測量的前端采用***、經(jīng)過特殊處理的堅固膜片，精湛的力學傳遞結(jié)構(gòu)和封裝工藝使其具有結(jié)構(gòu)緊湊、抗震動、抗頻繁高壓沖擊、抗堅固沙石沖擊、耐磨損等特點。是石化行業(yè)理想的壓力測量儀表。寧夏立柱式壓力變送器推薦大氣壓力變送器作為變送器家族的一員有著一定的市場使用率。這與大氣壓力變送器的重要作用有關(guān)。</p><div

在壓力變送器的眾多技術(shù)參數(shù)中，過載能力是一個重要參數(shù)指標。我們怎樣理解壓力變送器的過載能力,這對壓力變送器的正常使用又有什么重要意義呢？接下來我們一起，一層層揭開這個神秘的面紗。 </p> <p> 過載:過載就是負荷過大，超過了設(shè)備本身的額定負載，產(chǎn)生的現(xiàn)象是電流過大，用電設(shè)備發(fā)熱，線路長期過載會降低線路絕緣水平，甚至燒毀壓力變送器設(shè)備或線路。 </p> <p> 過載能力:過載能力指的是壓力變送器超過額定限值以后能夠承受的能力范圍。在通信電源領(lǐng)域，設(shè)備有標稱額定值標示其所能承載的負荷，而設(shè)計時候往往會留有余量，該余量被稱為過載能力，通常用于描述UPS性能。 </p> <p> <br /> </p><p> 但是過載能力也有一個度，一般是150%的范圍內(nèi)，（星儀壓力變送器的過載能力能達到滿量程的200%或者是120MPa。）使得壓力變送器在瞬間環(huán)境影響造成的超量程中，也能免受損壞，保護芯體等元器件不被燒毀等。對我們的壓力變送器起到很好的保護作用。 </p> <p> 過載能力是每種壓力變送器都要考慮的，因為在壓力變送器的使用過程中，很有可能會出現(xiàn)測量值大于量程的情況，只有設(shè)計了過載保護的變送器才能更好的使用，也才能使用得更久。所以不管是買什么類型的壓力變送器，一定要了解它的過載能力是多少，這樣才能更好的方便使用，在未來使用過程中也不會出現(xiàn)由于過載燒壞電路的情況。 </p> <p> 在這里也要提醒大家這是個瞬間造成過載的保護措施，我們在選購壓力變送器時，還是要對量程范圍作出精確的判斷，這是壓力變送器長期穩(wěn)定工作的基礎(chǔ)。壓力變送器把壓力信號傳到電子設(shè)備，進而在計算機顯示壓力。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="寧夏立柱式壓力變送器推薦,壓力變送器" src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439507441406/8167624.png"></div><p> 壓力變送器的內(nèi)部結(jié)構(gòu)主要指得是其殼體內(nèi)部的各種元器件，這也是壓力變送器性能好壞的主要因素。主要包括：固定銅片、集成芯片、隔離環(huán)、擴散硅芯體、阻尼等。 </p> <p> 固定銅片： </p> <p> 在技術(shù)較為成熟、品質(zhì)較好的壓力變送器產(chǎn)品中，都會在內(nèi)部添加固定銅片。固定銅片能夠很好的提高絕緣度、抗震性和接地穩(wěn)定性。部分廉價壓力變送器為節(jié)約成本則不會添加固定銅片。 </p> <p> 集成芯片： </p> <p> 集成芯片的品質(zhì)能夠很好的保障壓力變送器的抗干擾性和穩(wěn)定性。良好壓力變送器的集成芯片都是采用國際先進的集成芯片，散件拼裝的電路芯片抗干擾性差，穩(wěn)定性差。 </p> <p> 隔離環(huán)： </p> <p> 壓力變送器添加隔離環(huán)能夠提高產(chǎn)品的絕緣度，對壓力變送器起到很好的保護作用。 </p> <p> 擴散硅芯體： </p> <p> 先進的壓力變送器采用進口國際先進硅晶圓擴散硅芯體，這是壓力變送器高精度高、長期穩(wěn)定性的保障。壓力變送器的價格差別主要體現(xiàn)在這個上邊。劣質(zhì)芯體長期穩(wěn)定性差，也不能保證壓力變送器的測量精度。 </p> <p> 阻尼： </p> <p> 在壓力變送器內(nèi)部添加阻尼，為的是提高其抗沖擊的性能，更好的對壓力變送器內(nèi)部其他結(jié)構(gòu)進行防護，避免瞬間的過壓對壓力變送器造成沖擊損壞。起到很好的保護作用。 </p> <p> <br /> </p> <p> <br /> 當被測量是單向量，而且對其方向性要求較高，則應(yīng)選擇其它方向靈敏度小的變送器。寧夏立柱式壓力變送器推薦</p><p style="text-indent:25px">壓力變送器的使用溫度是-40～85℃，但實際使用時比較好在-20~70℃以內(nèi)。寧夏立柱式壓力變送器推薦</p><p> 不同類型壓力變送器使用注意事項： </p> <p> 壓力變送器經(jīng)過長期的市場應(yīng)用和技術(shù)研發(fā)，其成員不斷擴大。針對一些特定使用場合的壓力變送器越來越多。這符合整個變送器行業(yè)發(fā)展細分化的需求。不同類型的壓力變送器不僅在特點上有差異，在注意事項上也是有一定的區(qū)別的。向大家講解一下特殊類型壓力變送器的一些使用注意事項。 </p> <p> 高溫型壓力變送器：在使用過程中注意不要讓介質(zhì)溫度超過壓力變送器的工作溫度。必要時，需加裝冷卻裝置（冷凝管、盤管）。 </p> <p> 防爆型壓力變送器：本安防爆型壓力變送器必須配備安全柵和本安電源才可在危險場所使用。 </p> <p> 防水型壓力變送器：為了抵消大氣壓力，線纜內(nèi)部配有導氣管，產(chǎn)品接線處必須保障干燥通風。 </p> <p> 衛(wèi)生型壓力變送器：衛(wèi)生型壓力變送器底部膜片采用的是無近壓孔、無腔平面結(jié)構(gòu)。需要注意壓力變送器的膜片非常脆弱，千萬不能用外物碰觸！膜片變形可以導致測量誤差不準確，如膜片損壞壓力變送器則無法使用。寧夏立柱式壓力變送器推薦</p></p><br /><p>文章來源地址:
