MANOTHERMBeierfeld GmbH -企业介绍
北威州的ARMATURENBAUGmbH 是一家拥有长年生产压力测量仪器传统的中型企业,它的前身是1903年成立的位于德国Halle/Saale的 August Beer 公司。大约180员工为了公司的前途不断地努力工作。
MANOTHERMBeierfeld GmbH的前身是撒克逊州的“Meßgerätewerk Beierfeld”。自1957年以来,这里生产工业用压力和温度测量仪器以及气体压力温度计、保护管、接触压力表、真空计,
1991年MANOTHERMBeierfeld GmbH 作为 ARMATURENBAU GmbH 的子公司私有化。
自从1957 以来MANOTHERM 这个标记就代表着传统和质量。
在我们的公司驻地Beierfeld 大约有110 名员工。
MANOTHERMBeierfeld GmbH 客户主要分布在德国东部、东欧、前苏联国家和中国这些地区和国家之中。
我们的产品范围包括高价值的压力表和温度测量仪器,多年来在全球范围内享有极高的声誉。我们能够很自豪地说,客户高度赞誉我们的压力和温度测量仪器的质量和相应的技能以及可靠性。
我们不断地为客户量体裁衣,提供适合各种应用的压力表和温度测量技术。如膜片弹簧压力表、SF6气体密度表、真空压力表、差压表,带电信号办理出压力表以及温度测量仪器,如双金属温度计和相应的保护管都拥有广泛的适用性,并且还不断地投入于新的使用领域中。
我们也为您提供特殊使用领域的解决方案,例如低温压力表、轨道压力表、超高纯气体压力表或者安全压力表。
我们已通过DIN EN ISO 9001:2008 的认证。

Accessories for limit switch contact assemblies for inductive limit switch assemblies (data sheet 9532)
Switch amplifier intrinsically safe

These switch amplifiers are suitable for intrinsically safe applications.
The instruments transfer binary signals of limit switch contact
assemblies preferably with inductive limit switch assemblies
(NAMUR-sensors), from the potentially explosive area into the
secure area.
The proximity sensor or switch controls the load in the secure area
via a change-over relay contact. The output changes the status if
the status of the input signal is being changed. The normal output
status can be reversed via switch S1. Switch S3 is being used to
switch the lead error detection of the field circuitry on or off.
During the error status the relays fall and the error is being indicated
via the LAD according to NAMUR NE44.
Instruments with bistable relays (KFA6-SR2-Ex2.W.IR) are
being applied for filling level- and pump control and in other
switch applications. The instrument is being set by an active
signal at input I and is being reset by an active signal at input II.
The direction of action of the inputs I and II is programmable.
The lead error control of the field circuitry is being switched on and
off via switch 3. During an error condition or an power failure the
change-over relay contact falls and the error is being displayed via
NAMUR NE 44. If the lead error is remedied, the relay backspaces
in the condition of the error indication.
If the instrument is being supplied with energy after the power
failure, the relays backspace into the initial status.
