The Enviko SK-AC vibrating wire anchor cable load cell monitors the load on anchor cables, rock anchors, anchor bolts and arch supports, as well as other heavy loads. Each cell contains 4 to 6 high-precision vibrating wire sensors that together measure the total load. A built-in temperature sensor records ambient temperature, and a smart chip can be added on request.
