HYDAC贺德克流量开关电气HFS 2100 - 机械  中文描述

可用的版本：标准; ATEX

HFS 21002100系列HYDAC流量开关是基于位置无关的浮力变送器的测量原理。检验介质移动的弹簧加载浮于流动的方向，这取决于流速。簧片接点装在装置的外部，因此也流电路的外面。当浮子内的磁铁到达预设位置时，舌簧触点开关。为了保护它不受外界的影响，这是投在无级可调的住房。该装置被构造成这样的可靠限制值监视是可能的，甚至与粘度的变化。为此，运动粘度可以变化600之间30和厘沲。其应用领域包括：

 中环。润滑
- 油循环。润滑
- 变形金刚
- 冷却系统和电路
- 润滑回路
- 液压系统
- 泵
- 自动焊接设备和激光设备
- 化工
- 研究和开发

也可用于爆炸危险区域ATEX版本。
 

HYDAC贺德克流量开关电气HFS 2100 - 机械  英文描述

Available versions:
Standard; ATEX

The HYDAC flow switches of the HFS 2100 series are based on a position-independent buoyancy transmitter measurement principle. The test medium moves a spring-loaded float in the direction of flow, depending on the flow rate. A reed contact is fitted outside of the device and thus also outside of the flow circuit. When the magnet inside the float reaches the preset position, the reed contact switches. In order to protect it against external influences, it is cast in a steplessly adjustable housing. The devices are constructed in such a way that dependable limit value monitoring is possible, even with viscosity changes. For this, the kinematic viscosity can vary between 30 and 600 cSt. Areas of application include: - Central lubrications
- Oil circulating lubrications
- Transformers
- Cooling systems and circuits
- Lubrication circuits
- Hydraulic systems
- Pumps
- Welding machines and laser plants
- Chemical industry
- Research and development
