8710型气体质量流量控制器 (MFC) burkert

类型描述

8710 型质量流量控制器 (MFC) 尤其适用于腐蚀性气体的质量流量控制，这类气体需要一个介质隔离的传感器。毛细管热传感器可以实现快速响应。一个直动式 Bürkert 比例阀作为执行元件，确保了良好的响应灵敏度。集成 PI 控制器，令 MFC 具备卓越的控制特性。8710 型设备可以针对两种不同的气体进行校准，用户可以在两者之间进行切换。作为电气接口，既提供模拟标准信号，也提供现场总线。

（2）测量精度和重复性高

（3）适用于腐蚀性气体

（4）选配：现场总线接口

 

类型 8710 - Mass Flow Controller for Gases (MFC)

类型描述

The mass flow controller (MFC) Type 8710 is especially suited for regulating the mass flow of aggressive gases, which need a sensor which is not in direct contact with the gas. The thermal capillary sensor reaches fast response times. A direct-acting proportional valve from Bürkert guarantees a high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC. Type 8710 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available.

Nominal flow ranges from 0.005 lN/min to 15 lN/min

High accuracy and repeatability

Applicable for aggressive gases

Optional: Fieldbus interface
