total earth pressure cell

A total earth pressure cell measures the combined stress from soil, water, and any overlying structure at a single plane. In practice, you place the cell inside the fill or cast it into concrete, and it sends a signal proportional to the pressure acting on its diaphragm. Kingmach's cells are built with stainless steel housings to resist corrosion in wet environments, and the diaphragm is often a thin, hardened alloy designed to flex under load without permanent deformation. Most models use a fluid-filled inner cavity that transmits pressure to a sensing element; vibrating wire sensors are common because they resist signal degradation over long cables and offer good long-term stability. If the project requires a different output, strain gauge-based versions are also available. Kingmach can adjust the pressure range from tens of kilopascals up to several megapascals, depending on whether the job is a shallow utility trench or a deep mine stope. Temperature compensation is built into the design, typically through a thermally matched fluid or a secondary temperature sensor. Installation accessories like soil pads, mortar blocks, and junction boxes are included to make the process less guesswork. The cells are shipped with calibration sheets that show the specific sensitivity and zero offset for that unit, so you can plug the numbers directly into your data acquisition system. Because no two sites are the same, Kingmach also takes custom orders for non-standard dimensions or mounting brackets, working off sketches from the project engineer.
