ELC-31V is a vibrating wire type center hole load cell used to determine the load in rock bolts, tieback anchors, etc. It is filled with fluid with a vibrating wire pressure sensor attached to it, to convert the load into a frequency output.
A solid load cell for stress measurement in tunnel supports and struts is also available on request.
