Product Description

Overview

The Enviko SK-AB vibrating wire anchor bolt load cell, also called a bolt stress meter, measures bolt load and its changes online. It is used to monitor bolt preload and current stress in shield tunnel segment bolts, steel structure bolts and post-tensioned prestressed anchors. A built-in temperature sensor records ambient temperature, and a smart chip can be added on request.

Key Features

Direct measurement of bolt preload, more accurate than controlling preload by torque
Rated capacities of 200, 500, 1000 and 1500 kN
50% overload capacity
Online, continuous monitoring of load changes
Built-in temperature sensor; optional smart chip

Applications

Shield tunnel segment fixing bolts
Steel structure bolted connections
Post-tensioned prestressed anchors
