5. Operation
•
Connect the thermocouple sensor to the sensor
box and bring it into contact with the test sur-
face.
•
Wait for temperature compensation to com-
plete before taking readings.
6. Applications
Measurements involving very low temperatures in
liquified gases
Measuring temperature at points that are ex-
tremely difficult to access on account of the ex-
periment set-up – this is facilitated by a probe
1.20 m long and a small diameter of only 1.5 mm.
Measurements conducted in the hot region of a
flame without damaging or destroying the tip of
the sensor
7. Sample experiments
Experimental demonstration of Newton's law of
cooling

cooling
The type K immersion sensor U11854 is used in this
experiment.
•
Connect the equipment as shown in Fig. 1
above. Switch on the 3B NETlog
wait for the interface to automatically detect
and identify the sensor.
•
Prepare the interface for recording readings
over a time period of 10 hours, i.e. every
0.36 s, a total of 100,000 readings.
•
Fill approximately half the vessel with boiling
water (100°C approx.).

Subsequently, start taking readings. After com-
pleting the experiment, plot the cooling curve.
