How it works
1
-
Sensor cable
2
-
VW sensor
(no elasticity)
3
-
Stress cell body
-
comprises of two stainless steel rectangular plates welded
together around their periphery, leaving a thin space between the plates which is then
filled with an relatively incompressible de
-
aired fluid. Pressure applied normal to the plate
is balanced by a corresponding build up of internal fluid pressure which is measured by
the sensor.
4
-
Mounting lug
-
provided at each corners of the cell body to fix the cells in place while
the shotcrete is applied.
5
-
Pressure (pinch) tube
-
this is filled with a relatively incompressible de
-
aired fluid
and is connected at one end to the fluid filled space between the plates and the other
end is capped. The purpose of this tube is to inflate the cell once the concrete is cured.
