INTRODUCTION
The XZR500 MSRS (5) assembly is placed perpendicular to the tubing system. The
XZR500 furnace (4) and the XZR500 MSRS (5) are placed inside a cast aluminum
enclosure which is made of two parts sealed with a 5mm diameter viton O-ring. It is
dust proof and waterproof and can be mounted outdoors. The cable gland (17) is made
of brass.
The whole set is mounted on the stack with a steel fl ange which is welded on the
XZR500 outer tube. Michell Instruments can provide an optional mounting kit containing
a counter fl ange with threaded rods (if needed please refer to Appendix G).
All the gaskets (6, 7, 8 and 9) placed on the tubes are made of carbon fi ber.
A high temperature “gasket box” type device guarantees that the sealing head is airtight.
For dimensions of the measuring probe see Appendix D.
1.2.2 Control Unit
The Control Unit provides the Human Machine Interface (HMI) for the XZR500 analyzer.
It is housed in a metal case with a screen and three touch buttons to allow access to
menus. Inside there is a motherboard, a micro-controller and a display PCB. The output
signals and alarms are all accessed through the Control Unit.
Oxygen concentration is displayed on the screen as default and has one decimal
point as standard (a second decimal place can be requested as an option). Other
parameters available through the HMI are Furnace Temperature, Thermocouple Junction
Temperature, MSRS Voltage and Ambient Pressure (in mbars), if the optional pressure
sensor is ordered.
Con fi guration of alarms and output signals as well as calibration functions are all carried
out through the HMI of the Control Unit.
The digital display panel of the analyzer is shown in
Figure 5.
