The ring force transducers in geotechnical version are hydraulic force measuring units which, in conjunction with measuring or display instruments, can directly display the measured values or output them as an analogue signal. It is an extremely robust design in line with the requirements of geotechnical engineering.<\/p>\n<p>The force is measured using the principle of hydraulics &#8211; the force acting on a piston leads to a pressure increase. This is then visualised, either directly by a connected display instrument or converted by means of a pressure sensor into an analogue signal.<\/p>\n<\/div>\n<div class=\"column is-half\">\n<p>With these hydraulic force measuring units, clamping forces are detected at the anchor head in a simple way and brought directly to the display. The force measuring units are used for continuous monitoring of anchors and other bracing rods\/ cables. Applications for hydraulic force measuring units can be found in the field of geotechnology in various fields such as tunnel construction, bridge building and slope stabilisation.<\/p>\n<h6>Specifications per VDI\/VDE\/DKD 2638<\/h6>\n<table>\n<tbody>\n<tr>\n<td colspan=\"2\" width=\"661\">Model F6171<\/td>\n<\/tr>\n<tr>\n<td width=\"265\">Rated force
