DESCRIPTION
Shotcrete stress cell measures stress in tunneling lining. Shotcrete stress cell comprises two
rectangular steel plates welded together and connected with vibrating wire sensor when stress
increase in shotcrete, two welded plates change the pressure using filled oil in rectangular plates and
transfer the pressure to the sensor.
APPLICATION
Stress measurement in tunnel lining
Backfill pressure measurement in mines
Foundation bearing Pressure measurement
ADVANTAGE
The advantage of vibrating wire sensor it gives frequency signal rather than voltage signal
FEATURES
Long term stability
Reliable & Rugged design
