Stream Selector

• Samples from different streams are fed to inlet of solenoid valves. System consists of 3 way solenoid valves. Outputs from solenoid valves are connected to single tube. 
• Using unique features of controller, sample from the desired stream is fed to the analyzer by switching on the solenoid valve of desired stream.
• Once sampling is over, next stream is selected. The sequence continues.
  
• Sample switch over: Time based or external trigger based

3 - Way Solenoid Valve (230 V AC, 50 Hz)

End Connection: 1/4" NPT (F), Universal Type, MOC: SS316

Double Compression Type Fittings and Tube

System also accepts analog output (current: 4-20 mA)

From Analyzer. It converts this value to engineering

Value (%, ppm, ppb etc).

It can give multiple analog outputs (Current output: 4-20 mA) proportional to sample value. Measured sample values are displayed on local display. It can be transmitted on communication port (RS-232 or RS-485).

One can connect dot matrix printer (serial interface) for online printing. Alternatively data can be acquired by application software installed on PC thro  MODBUS protocol.
