TOPAS SYS520气溶胶切换阀

The Sample Switching Unit SYS 520 has been developed for the determination of fractional separation efficiencies of filters or filter media at two different sampling points, that is before and after the filter.

 This task can be realized with the sample switching unit SYS 520 with only one particle size analyzer economically and reproducible. With the switching unit an automated and safe exchange between the measurement of sampling lines I, II and a sampling line of a purge routine is possible (using the integrated HEPA filter).

 优点：

 Switching between different sampling points

Determination of fractional efficiency curves

Protection against to high particle loading of the particle measuring device by temporal limitation of sample flow

Sample switching possible at difficult to access positions

应用：

The SYS 520 is designed for direct connection to the Laser Aerosol Particle Size Spectrometer LAP 322.

The models SYS 520/P and SYS 520/H are integrated in test stand solutions and have a hardware interface that both transmitsthe control signals and ensures the power supply.

The model SYS 520/S is designed for use with various particle measurement devices, like Particle Counter for Air and Gases LAP 340. The control of the device via a serial communication port (RS 232) by means of a computer.

With the help of analysis and control software PASWin or the software for filter test rigs PAFWin, it is easy possible to switch manually or automatically between two sampling lines.

已经开发了样品切换单元SYS 520，用于在过滤器之前和之后的两个不同采样点处确定过滤器或过滤介质的分级效率。

该任务可以通过样品切换单元SYS 520实现，其中仅需一个粒径谱仪经济且可再现。通过切换单元，可以在线采样I，II两个采样口测量，和吹扫程序的采样线之间进行自动且安全的交换（使用集成的HEPA过滤器）。

优点：

在不同的采样点之间切换

分级效率曲线的确定

通过限制样品流量，防止颗粒测量装置的高颗粒负载

在难以进入的位置进行样品切换

应用：

SYS 520设计用于直接连接激光气溶胶粒径光谱仪LAP 322。

SYS 520/P和SYS 520/H型号集成在试验台解决方案中，并具有硬件接口，可以传输控制信号并确保电源供应。

SYS 520/S型号设计用于各种粒子测量设备，如空气粒子计数器和气体LAP 340.通过计算机通过串行通讯端口（RS 232）控制设备。

借助分析和控制软件PASWin或过滤器测试台PAFWin软件，可以在两条采样线之间手动或自动切换。
