產(chǎn)品應(yīng)用和型號(hào)選擇
波登管壓力表用于液體或氣體介質(zhì)的壓力(或真空)測量,測量范圍0-0.6和0-4000bar(0-10至0-60000psi)。
在選擇型號(hào)時(shí),必須符合EN837-2的要求。特別是用戶必須確保壓力介質(zhì)不能腐蝕任何浸濕零件。
有關(guān)應(yīng)用詳細(xì)說明,我們*DIN e.V “壓力表DIN EN837” 說明,由Beuth Verlag出版。此外,可查看我們上PDF文件關(guān)于安裝與操作指示的解釋說明, 關(guān)于安裝與操作指示B1的解釋說明。
Application and Selection
Bourdon tube pressure gauges are applicable for measuring pressure (and/or vacuum) between 0-0.6 and 0-4,000 bar (0-10 to 0-60,000 psi) of fl uid or gaseous media.
EN 837-2 has to be considered for the selection of the suitable model.In particular, the user has to ensure that the pressure medium may not corrode any of the wetted parts.
For a more detailed description of application criteria we recommend the commentary of the DIN e. V. "Überdruckmessgeräte nach DIN EN 837", published by Beuth Verlag. Furtheremore, you will fi nd
helpful instructions in our Mounting and Operating Instructions B1,available as pdf fi le on our web site.

結(jié)構(gòu)
所有型號(hào)的內(nèi)部構(gòu)造基本都一樣。
波登管,螺紋連接機(jī)構(gòu),刻度盤和指針一起構(gòu)成完整的測量裝置。
外殼與窗口環(huán)是為了保護(hù)壓力元件免受外界影響。
Construction
The internals are basically constructed equally for all models.
Bourdon tube, socket with thread connection, movement, dial and pointer together constitute the complete measuring device.
The case and the ring with window just protect the pressure element against external infl uences.
外殼填充
壓力表外殼充液是為了防止由于劇烈震動(dòng)或脈動(dòng)導(dǎo)致的損壞,也可防止冷凝。(室外安裝)
標(biāo)準(zhǔn)充液的填充型號(hào)(型號(hào)G)是甘油,用于電氣附件儀器時(shí),采用的一種特種油( 型號(hào) Oe).
溫度限制見第5頁。
Case Fillings
Liquid fillings in pressure gauge cases are used to protect the internals against damages caused by severe vibrations or pulsations and to exclude condensation(outdoor installation).
The standard fi lling fl uid for fi lled versions (models ...G) is glycerine, and it is a special
oil when the instruments are provided with electrical accessories (models ...Oe).
Temperature limitations see page 5

• at steady load: full scale value
• at dynamic load: 90% of the full scale value(>0-2,500 bar/30,000 psi max. 65%)
• overpressure: max. 130% of full scale value(>0-2,500 bar max. full scale value)

• at steady load: 75% of the full scale value
• at dynamic load: 65% of the full scale value
• overpressure: full scale value
Advice
According to EN 837-1 the normal use of all instruments is recommended, so that the maximum pressure load does not exceed 75% of the maximum scale value for steady loads or 65% of the maximum scale value for dynamic loads, to guarantee a long service life of the meatrological features.
Furthermore, it is reccommended, not to use the starting range(up to approx. 20%), because the measuring deviation is relatively enormous refering to the value.
