Key Features of Vibrating Wire Earth/soil Pressure Cell

• The flexible, circular flat pressure pad is constructed from two stainless steel discs electron beam welded around the periphery.
• The pressure pad is connected to the vibrating wire pressure sensor through a 6 mm diameter x 165 long stainless steel tube.
• The narrow cavity inside the pressure pad and tube is fluid filled.
• Pressure applied by earth on the capsule is transmitted through the fluid to the vibrating wire pressure sensor, which converts it into an electrical signal.
• Range [mm wc]: 300, 500, 1000, specify
• Accuracy: ± 0.1 percent fs
• Non-linearity: ± 0.5 percent fs
• Temperature limit: -20 to 80 degree C
