BURKERT电磁阀0117系列,BURKERT
BURKERT电磁阀从机械式流量计到电子技术流量计的革新是流量计重要的发展趋势之一。电磁流量计、超声波流量计、涡街流量计和V锥流量计(孔板流量计)利用电气原理工作,从而避免了机械流量计工作中需要更换的运动机件。同时,自诊断功能被引入流量计中,使得流量仪表不仅仅是简单的测量工具,更多地为了系统维护的目的,例如:空管道侦测和自检验等。并且,在电子流量计中结合的通信技术后,使得控制人员能够远程实时获取生产现场的流量数据和历史数据。
。接通时,磁芯受到吸引,由此克服弹簧力。阀门特别适合流量很小的、液态或气态的侵蚀性介质。

2/2-way-mini Solenoid Valve
Type 117 is a normally-closed direct-acting
plunger-type solenoid valve with PTFE-coated
diaphragm. The diaphragm isolates the fluid
from the solenoid system.
When deenergized (in circuit function A)
the valve is closed by spring action. When
energized, the solenoid armature is drawn
in 2/2-Way, G 1/8, UNF 1/4-28 Fluid
Co
ntrol Systems against a spring to open
the valve. The solenoid epoxy encapsulation
efficiently dissipates the heat generated by
the coil.
• Compact design
• Low electrical power co

据Frost&Sullivan的研究,当前约89.0%的流量计采用mAHART通信协议,因为采用mAHART通信协议的流量计在安装难度和操作要求上都低于采用现场总线协议的流量计,并且引入现场总线系统对用户来说也是一项不小的成本。但是,随着行业用户不断提高自动化水平,希望从流量测量中获取除了流量数据以外更多的信息,比如,诊断信息和状态检测等,这些数据传送都需要依赖现场总线支持。而且,西门子和艾默等厂商生正在着力推行现场总线协议的流量测量技术。相信,这必将推动现场总线协议流量计在各个行业的应用前景。
此外,无线技术流量计也正在逐步被用户所接受,恶劣环境中的流体测量对无线技术来说是一个很好的应用空间。不过,用户完全接受并普及无线技术流量计还需要一定的时间。
