Relative Pressure Sensor, ±100 hPa U11321
Instruction sheet
03/08 Hh
1. Safety instructions
•
To avoid permanent damage to the internal
semiconductor
sensor,
permitted relative pressure of 4000 hPa must
never be exceeded.
Only suitable for use with non-corrosive gases such
as air, helium or nitrogen.
•
Do not allow the sensor element to come into
contact with water.
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
the
maximum
TM
unit.
