Title:
DIFFERENTIAL PRESSURE MEASUREMENT SYSTEM
Document Type and Number:
Japanese Patent JP2004177280
Kind Code:
A
Abstract:

To provide a differential pressure measurement system capable of easy attachment or detachment while capable of preventing a differential sensor from being damaged owing to an artificial mistake.

The measurement system is provided with: the differential sensor 11; a 1st protector 20; a 2nd protector 30; a 1st piping 41; a 2nd piping 42; a 3rd piping 43; a 4th piping 44; a 5th piping 45; a 6th piping 46; a 7th piping 47; and an 8th piping 48. A valve 25 provided with the 1st protector 20 is closed when the differential pressure between the pressure of a high input port 21 and that of low gage port 24 is lower than a predetermined value, and is opened when the differential value leaches the predetermined value. A valve 35 provided with the 2nd protector 30 is closed when the differential pressure between the pressure of a high input port 31 and that of a low gage port 34 is lower than a predetermined value, and is opened when the differential pressure reaches the predetermined value.
