 詳細說

適用范圍:
精密壓力表主要用來校驗工業(yè)用普通壓力表,精密壓力表也可在工藝現(xiàn)場精確的測量對銅合金和合金結(jié)構(gòu)鋼等材質(zhì)無腐蝕性、非結(jié)晶非凝固介質(zhì)的壓力。精密壓力表在標(biāo)度線下設(shè)置有鏡面環(huán)(A型B型),在使用中讀數(shù)更清晰精確,并帶有調(diào)零裝置(B型)
 

外殼直徑
150MM 徑向
壓力范圍
-0.1~~60MPA
外殼材質(zhì)
鐵質(zhì)黑色電泳
機芯
銅合金
精確度等級
0.4級、0.25級
溫度影響
使用環(huán)境溫度如偏離20±3℃(0.4級)或20±2℃(0.25級)時,則須考慮溫度附加誤差0.4%/10℃。使用環(huán)境溫度如偏離20±3℃(0.4級)或20±2℃(0.25級)時,則須考慮溫度附加誤差0.4%/10℃。
結(jié)構(gòu)原理
精密壓力表由導(dǎo)壓系統(tǒng)(包括接頭、彈簧管等)、齒輪傳動機構(gòu)、示數(shù)裝置(指針與度盤)和外殼(包括表殼、表罩、表玻璃等)組成。儀表有較好的密封性并設(shè)有檢封裝置,能保護其內(nèi)部測量機構(gòu)免受機械損傷和污穢侵入。 儀表的作用原理是基于彈性元件(測量系統(tǒng)中的彈簧管)變形。在被測介質(zhì)的壓力作用下,使彈簧管之末端產(chǎn)生相應(yīng)彈性變形——位移,借助于拉桿經(jīng)齒輪傳動機構(gòu)的傳動并予放大,由固定于齒輪軸上的指針逐漸將被測值在度盤上指示出來。

0.25級0.25級精密壓力表既0.25級標(biāo)準(zhǔn)壓力表

關(guān)于0.25級精密壓力表     0.25級精密壓力表是一種按精度等級分類的稱謂, 所謂0.25級是指該精密壓力表的精度等級為其測量上限值的±0.25%,亦既允許的最大示值基本誤差為其測量上限值的±0.25%.如照片所示,該精密壓力表的精度等級為0.25級,測量上限為1.6MPa,其允許的最大示值基本誤差為: 1.6MPa×0.25%=±0.004MPa

     中華人民共和國國家標(biāo)準(zhǔn) GB/T 1227-2002 精密壓力表中規(guī)定,0.25級,測量上限為1.6MPa的精密壓力表的標(biāo)度分格總數(shù)為320分格,其最小分格值則為: 1.6MPa÷320分格=0.005MPa/分格.也就是說,0.25級,測量上限為1.6MPa的精密壓力表的最大示值基本誤差不得超過±0.8個最小分格,既±0.004MPa.

    0.25級精密壓力表的實際示值基本誤差(包括零點誤差)需要在參比工作條件下測定, 所謂參比工作條件有三,一是儀表應(yīng)處于正常工作位置(未指明時,正常工作位置系指垂直安裝),二是負(fù)荷均勻變化,三是周圍環(huán)境溫度為20℃(0.25級精密壓力表允許偏差±2℃).

    較其它精度等級的精密壓力表,0.25級精密壓力表在實際工況中是一種相對應(yīng)用較多的精密壓力表. 其結(jié)構(gòu)成熟、指示連續(xù)且直觀、性能穩(wěn)定且耐用、量限段完整且價格適中等獨特的優(yōu)勢使其得到了十分廣泛的應(yīng)用.

注:

關(guān)于0.25級精密壓力表 0.25級精密壓力表是一種按精度等級分類的稱謂, 所謂0.25級是指該精密壓力表的精度等級為其測量上限值的±0.25%,亦既允許的最大示值基本誤差為其測量上限值的±0.25%.如照片所示,該精密壓力表的精度等級為0.25,測量上限為1.6MPa,其允許的最大示值基本誤差為: 1.6MPa×0.25%=±0.004MPa 中華人民共和國國家標(biāo)準(zhǔn) GB/T 1227-2002 精密壓力表中規(guī)定,0.25,測量上限為1.6MPa的精密壓力表的標(biāo)度分格總數(shù)為320分格,其最小分格值則為: 1.6MPa÷320分格=0.005MPa/分格.也就是說,0.25,測量上限為1.6MPa的精密壓力表的最大示值基本誤差不得超過±0.8個最小分格,±0.004MPa. 0.25級精密壓力表的實際示值基本誤差包括零點誤差需要在參比工作條件下測定, 所謂參比工作條件有三,一是儀表應(yīng)處于正常工作位置未指明時,正常工作位置系指垂直安裝),二是負(fù)荷均勻變化,三是周圍環(huán)境溫度為20℃(0.25級精密壓力表允許偏差±2℃). 較其它精度等級的精密壓力表,0.25級精密壓力表在實際工況中是一種相對應(yīng)用較多的精密壓力表. 其結(jié)構(gòu)成熟、指示連續(xù)且直觀、性能穩(wěn)定且耐用、量限段完整且價格適中等獨特的優(yōu)勢使其得到了十分廣泛的應(yīng)用.

0.25級精密壓力表是目前最主流的標(biāo)準(zhǔn)表,主要在校驗時做標(biāo)準(zhǔn)表使用,精密壓力表主要用來校驗工業(yè)用普通壓力表,精密壓力表也可在工藝現(xiàn)場精確的測量對銅合金和合金結(jié)構(gòu)鋼等材質(zhì)無腐蝕性、非結(jié)晶、 非凝固介質(zhì)的壓力。

溫馨提示:目前市場上比較主流的0.25級精密壓力表是YB-150B,其市場需求量最大,160MM的表盤因為和150MM表盤相比沒有什么優(yōu)勢價格卻比150MM的貴很多,所以YB-160市場需求不大。
