波登管压力表综述 弹簧管压力表 C型管压力表

常规功能General Features

产品应用和型号选择

波登管压力表用于液体或气体介质的压力(或真空)测量,测量范围0-0.6和0-4000bar(0-10至0-60000psi)。

在选择型号时,必须符合EN837-2的要求。特别是用户必须确保压力介质不能腐蚀任何浸湿零件。

有关应用详细说明,我们*DIN e.V “压力表DIN EN837” 说明,由Beuth Verlag出版。此外,可查看我们上PDF文件关于安装与操作指示的解释说明, 关于安装与操作指示B1的解释说明。

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.

结构

所有型号的内部构造基本都一样。

波登管,螺纹连接机构,刻度盘和指针一起构成完整的测量装置。

外壳与窗口环是为了保护压力元件免受外界影响。

 

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.

 

外壳填充

压力表外壳充液是为了防止由于剧烈震动或脉动导致的损坏,也可防止冷凝。(室外安装)

标准充液的填充型号(型号G)是甘油,用于电气附件仪器时,采用的一种特种油( 型号 Oe).

温度限制见第5页。

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

 

工艺连接

除个案外,我们的波登管压力仪表的外螺纹标准连接件如下:

?  ¼" BSP至 NCS 63

?  ½" BSP由 NCS 80

符合 EN837-1

但几乎所有型号也可提供:

¼" NPT或 M 12 x 1.5 至 NCS 63

½" NPT或 M 20 x 1.5 由 NCS 80

无额外费用

请注意: 连接件¼" BSP¼" NPT及 M 12 × 1.5的

zui大压力范围分别为 600bar (1-型) 和1000bar (3-型)。

能为客户定制各种版本型号。

Process Connections

With just a few exceptions the male standard connections of our bourdon tube pressure gauges are

• ¼" BSP up to NCS 63

• ½" BSP from NCS 80

in accordance with EN 837-1.

But almost all models are also available with

• ¼" NPT or M 12 x 1.5 up to NCS 63

• ½" NPT or M 20 x 1.5 from NCS 80

without extra charges.

Please note: Process connection ¼" BSP, ¼" NPT and M 12 x 1,5

max. pressure range 600 bar (type –1) resp. 1000 bar (type –3).

Numerous versions are available as custom-made products

 

表盘

表盘题字,压力范围,表盘间距以及表盘压力范围都符合EN837-1规定。

标准表盘是在白色背景上显示黑色刻度。压力范围和详细分解见第6页表格。

工厂序列号在表盘仪表上面,常规尺寸80(3’’)甚至以上,NCS63(2½’’)也被广泛使用

 

Dial

Dial inscriptions, pressure ranges, dial spacings as well as the dial markings for bar pressure ranges are in accordance with EN 837-1.

Standard dials show a black scale on a white background.Pressure ranges and subdivisions see table on page 6.

A factory serial number for reference is stated on the dial of gauges nom. sizes 80 (3") and above, extensively also NCS 63 (2 ½").

压力范围

EN837-1*的压力单位是Bar。

在型号概述中(见第7页),标准压力范围是以bar描述。

但实际上有各种压力单位,如psi(见第6页),kg/cm2 , kPa , MPa 等等。 多量程也可提供。

 

PressureRanges

Bar is the preferred unit of pressure according to EN 837-1.

In this model overview (on pages 7 ff) you will fi nd the standard pressure ranges stated in bar.

But in fact there are numerous different pressure units available,such as psi (compare page 6), kg/cm², kPa, MPa et al. Multi-scales are also possible.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

在致冷应用方面,我们的压力仪表对于不同的致冷剂提供各种特殊温度量程。

测量功能

Metrological Features

精度等级符合EN837-1

精度等级1.6 直至NCS 63

精度等级1.0 始于NCS80

精度等级是描述测量跨度的百分比公差滞后现象的极限值也是由精度等级明确规定。

请注意技术资料范围有限。

 

Accuracy Classes according to EN 837-1

Accuracy class 1.6 up to NCS 63

Accuracy class 1.0 from NCS 80

The accuracy class states the tolerance in percent of the measuring span. The limit value for the hysteresis is also defined by the accuracy class.

Please regard possible limitations on our data sheets.

 

极限载荷符合EN837-1

常规外壳尺寸 100 (4"), 160 (6"), 250 (10"), 4½"和96 x 96 (3.8" x 3.8"), 144 x 144 (5.7"x 5.7)

?    稳定载荷: 全量程值

?  动态载荷: 全量程值的 90% (≥ 0-2,500 bar/30,000 psi zui大65%)

超限压力: zui大为全量程值的130% (zui大全量程值≥ 0-2,500 bar)

常规外壳型号 40 (1½"), 50 (2"), 63 (2½"), 80 (3")

稳定载荷:全量程值 75%

动态载荷:全量程值 65%

超限压力: 全量程值

建议

建议依据EN837-1正常使用仪器,以便zui大压力载荷不超过稳定载荷的zui大刻度值75%,或动态载荷的zui大刻度值 65%,以确保测量控制逻辑特性的的*可靠性。

此外,建议不要使用初始范围(约20%以下),因为存在较大的测量误差。

 

Load Limits acc. to EN 837-1

Nom. case sizes 100 (4"), 160 (6"), 250 (10"), 4½",and 96 x 96 (3.8" x 3.8"), 144 x 144 (5.7"x 5.7")

• 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)

Nom. case sizes 40 (1½"), 50 (2"), 63 (2½"), 80 (3")

• 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.
