> <

Spot weldable strain gauges serie ST1 are designed for application on steel structure or reinforcement bars where strain monitoring is required and the installation space is limited.

It consists of a sealed tube containing a Vibrating Wire element with weldable anchors at each end. 

The anchors are separated by a small floating stainless steel tube with ‘O’ ring seals that protect the Vibrating Wire from water ingress.

A factory fitted, four core screened cable connects the coil to the readout unit.
