20.3. Sensor Orientation
Figures 22 and 30 show the sensor in a vertical orientation around the furnace for high
temperature measurements. The MS2W should be clamped onto the MS2WF so that the sample
cavity encapsulates the furnace. The MS2W sensor should not be in contact with the MS2WF
furnace.
Figure 30. Mounting the MS2W on the MS2WF
If low temperature measurements only are to be performed (no furnace) then it may be
advantageous to mount the sensor horizontally.
Note:
The sensor will detect the presence of the metal base. This is not a problem as
the instrument is zeroed before commencing readings, but the sensor clamp should
be checked to ensure that no movement of the sensor can occur. Similarly the probe
connecting cable should not be disturbed when measurements are being taken.
When the furnace is not in use, i.e. for low temperature measurements, the type ‘T’
thermocouple will be connected and selected, and coolant supplied to the system.
When the furnace is to be used, position the sensor as shown in figures 22/30 so that its most
sensitive detection region is located in the middle of the sample and at the thermal centre of the
furnace.
Note:
Allow the system to stabilise for 30 minutes with the MS2 meter running and water
flowing through the sensor for optimum low drift performance.
Note:
At switch on, the water pump will run at an elevated flow rate for a short time in
order to prime the system.
