The relative pressure sensor FW is used to measure relative pressures. The sensor is equipped with two measuring chambers via whose terminals pressure diff erences can be measured.

Range: 0 − ±100 hPa
Accuracy: ± 1%
Hose shaft: 4 mm Ø
Included in the scope of delivery: Silicone hose, 1 m.

Can be used to:
• measure the hydrostatic pressure in a water column
• measure the pressure diff erences in a Stirling engine D
