VW NATM Pressure Cell

Designed to measure total stress in concrete (shotcrete) linings in tunnels and other underground workings.

The instrument is associated with monitoring & control of construction by the New Austrian Tunnelling Method (NATM), also known as Sprayed Concrete Lining and sequential Excavation Method.
It is used for the monitoring of radial and tangential stresses within and on shotcrete lining, along with measurement of tunnel convergence and deformation.

Features:

	High accuracy and sensitivity
	Vibrating wire transducer assures long-term stability
	Easily connected to datalogging
