The quantification of environmental and installation conditions and the extent of influence considering their combined contribution towards inaccurate or exclusive measurements are to that degree limited. This experimental study investigated how two different strain transducers\u2014installed in a force-shunt configuration\u2014respond to thermo-mechanical loads when used to determine load distribution and position. Initial observations indicated that thermal effects at the installation site contributed to measurement inaccuracies or exclusive readings. The investigation quantified the impact of environmental and installation variables on measurement accuracy and found this influence to be indirectly linked to the mechanical properties of the substrate to which the strain transducers were mounted. Mounting bolt torque was determined to exert a negligible effect on strain measurement accuracy for the custom-built strain transducers. Nonetheless, both transducers failed to consistently return to the selected baseline at the start of experiments since thermal dependence persisted at the balanced state following the first cycle of loading. The research indicated that the custom-built force-shunt strain transducers are an effective means for mapping the profile and location of coal in shuttle cars, provided that the systems are subjected to continuous and cyclic rebalancing to maintain accuracy.<\/jats:p>","DOI":"10.3390\/s26082374","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T07:29:29Z","timestamp":1776065369000},"page":"2374","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Characterization of Full Bridge Strain Transducers for Haulage Equipment Payload Distribution Monitoring"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-9516-1757","authenticated-orcid":false,"given":"Jean-Pierre","family":"Strydom","sequence":"first","affiliation":[{"name":"Department of Mining Engineering, University of Kentucky, Lexington, KY 40504, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6529-137X","authenticated-orcid":false,"given":"Steve","family":"Schafrik","sequence":"additional","affiliation":[{"name":"Department of Mining Engineering, University of Kentucky, Lexington, KY 40504, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9799-4114","authenticated-orcid":false,"given":"Zach","family":"Agioutantis","sequence":"additional","affiliation":[{"name":"Department of Mining Engineering, University of Kentucky, Lexington, KY 40504, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8726-2107","authenticated-orcid":false,"given":"Matt","family":"Beck","sequence":"additional","affiliation":[{"name":"Department of Materials Engineering, University of Kentucky, Lexington, KY 40504, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0002-5921","authenticated-orcid":false,"given":"Joseph","family":"Sottile","sequence":"additional","affiliation":[{"name":"Department of Mining Engineering, University of Kentucky, Lexington, KY 40504, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,12]]},"reference":[{"key":"ref_1","unstructured":"Mine Safety and Health Administration (2025, November 09).
