Extensometer FEATURES Strain gage based sensor Alloy steel construction 2 Bolt holes IP66 Hermetically sealed protection Optional - EEx ia IIC T4 Hazardous area approval APPLICATIONS Tank weighing or level systems Agricultural equipment Rolling mill sensing Moment sensing Structural loading measurements Bridge structures DESCRIPTION The Model 178 extensometer is a load sensor designed for force measurement on any load-bearing structure. This extensometer is a complete solution for weighing, level control, stress and fatigue monitoring. The design also allows multiple sensors to be permanently mounted for more complex stress proiling and analysis. The Model 178 extensometer provides an ideal solution for non-intrusive level measurements for materials that are subject to uneven buildup, bridging, or sidewall collection. Also, liquids or wetted materials that are not suited for direct contact level measurement are an ideal application for the Model 178 extensometer. The design of the Model 178 makes it an excellent solution for retroitting existing structures without compromising the integrity of the vessel or structure.
