X-STREAM
The X-STREAM series analyzers offer a wide
range of available configurations and options,
to be combined according to the selected
model:
Measuring principles
Up to two out of all offered principles may be
combined within one analyzer model to provide
best adaption to the application.
For a detailled description of available
measuring principles:
Gas path design
Internal tubing with viton or, optional and
depending on application, PFA or stainless
steel.
In addition one or more of the following options
are available:
• Soleniod valve block
This option uses 4 internal solenoid valves
to control sample, zero, span gas 1 and
span gas 2. These gases are fed to the
analyzers to provide manual or controlled
automatic calibration (initialized
keypad, serial interface or digital inputs).
• Sample pump
Maximum flow rate 2.5 l/min
• Barometric Pressure sensor
(Measuring range 800 to 1,200 hPa)
Facilitates compensation of atmospheric
pressure variations to improve precision
of results (
cations, page 3-17).
Special sensors for e.g. corrosive gas on
request.
• Flow measurement
A flow sensor (option) can be used to

Heated box for physical components
•
All the physical components
optionally be installed inside thermostatted
box to minimize influences from ambient
tem-perature fluctuations.

components:
Interfaces
All models may be configured to use several
interfaces:
Standard:
• analog outputs
• serial interface (RS 485 or RS 232) with
Modbus protocol
• status signals (NAMUR; relay outputs)
Optional:
• 8 digital outputs & 7 digital inputs
