5. Example experiment
Recording a pV diagram for a G-model Stirling
motor using 3B NETlog
TM and 3B NETlab TM
Required equipment:
1 Stirling Engine G 1002594 / U10050
1 3B NETlog TM (115 V) 1000539 / U11300-115
or
1 3B NETlog
TM (230 V) 1000540 / U11300-230
1 3B NETlab TM 1000544 / U11310
1 Displacement Sensor 1000568 / U11371
1 Relative Pressure Sensor
±1000 hPa
1000548 / U11323
1 Sensor Holder for
Stirling Engine G
1008500 / U11372
1 DC Power Supply
0 – 20 V, 0 – 5 A (115 V)
1003311 / U33020
or
1 DC Power Supply
0 – 20 V, 0 – 5 A (230 V)
1003312 / U33020
Experiment leads 1002843 / U138021
• Set up the experiment as in Fig. 1.
• Wrap the thread around the displacement sen-
sor’s pulley as in Fig. 2.
• Turn on the 3B NETlog TM unit and wait for it to
automatically detect the sensor box.
• Connect the Stirling engine’s DC motor to the DC
power supply and set an output voltage of 6 V so
that the Stirling engine operates at medium
speed.
• Open the 3B NETlog TM template "Stirling engine G".
• Only allow the Stirling motor to operate at high-
speed for short periods so as not to overstress
the displacement sensor.
6. Disposal
• The packaging should be disposed of at local
recycling points.
• Should you need to dispose of the equipment
itself, never throw it away in normal domestic
waste. Local regulations for the disposal of elec-
trical equipment will apply.
