Membrane polymère

The OILSPY hydrocarbon detector works thanks to a polymer membrane developed in partnership with the Institut Français du Pétrole (IFP). It is fixed in extension between a return piston and a fixed axis. Upon contact with pollution, the membrane dissolves like a fuse, releasing the piston which activates a contact relay in the OILSPY housing. The TOR contact opens, the alarm is triggered.

Membrane rupture time under normal tension of approximately 150gr at 20°C:
Gasoline 4 seconds
Trichloroethylene 10 seconds
Kerosene 26 seconds
Diesel and heating oil 2 minutes
Crude oil 2 minutes
