2. Description
Relative pressure sensor with a measurement range
up to 100 hPa, suitable for measuring the pressure
on the piston of the Wilke-type Stirling engine
U8440480 (for a pV diagram).
For two-port measurement using the sensor, hose
connections are provided for two inputs.
The sensor box is designed to be detected
automatically by the 3B NETlog
TM
unit.

1 Sensor box
1 MiniDIN 8-pin connector cable, 60 cm long
1 Silicone hose, internal diameter 2 mm, 1 m long

hose connection of the sensor box and one of
the two hose connections of the Stirling
engine. The two hose connections of the
engine are identical in their function.
