Abstract
Provided is a pressure detection device including a pressure detection unit configured to detect a pressure to be transmitted to a pressure sensor, and a flow channel unit on which the pressure detection unit is disposed. The pressure detection unit) includes a pressure sensor and a conductive protective film disposed in contact with the pressure sensor, the conductive protective film breaking contact between the pressure sensor and a fluid. The conductive protective film is formed of a conductive fluororesin material including a fluororesin material and a conductive material dispersed in the fluororesin material and is connected to a ground portion maintained at a ground potential.
Claims4
A pressure detection device comprising:
- a pressure detection unit configured to detect a pressure to be transmitted to a pressure detection portion;
- and
- a flow channel unit having a flow channel formed therein, the pressure detection unit being disposed on the flow channel unit, wherein
- the pressure detection unit includes:
- the pressure detection portion;
- and
- a thin film-like protective portion disposed in contact with the pressure detection portion, the protective portion breaking contact between the pressure detection portion and a fluid, and
- the protective portion is formed of a conductive fluororesin material including a fluororesin material and a conductive material dispersed in the fluororesin material, and is connected to a ground portion maintained at a ground potential.
