Mass Measurement


Weighing, level control, stress and fatigue monitoring

October 2012 Mass Measurement

Vishay’s Model 178 extensometer is a load sensor designed for force measurement on any load-bearing structure. This extensometer provides the total solution for weighing, level control, stress and fatigue monitoring. The design also allows multiple sensors to be permanently mounted for more complex stress profiling and analysis.

The Model 178 provides the 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 this extensometer. The design makes it an excellent solution for retrofitting existing structures without compromise of the integrity of the vessel or structure.

The 178 has application in tank weighing or level systems, agricultural equipment, rolling mill sensing, moment sensing, structural loading measurements and bridge structures.

Temperature monitoring in the metal casting process
Instrotech Temperature Measurement
During metal casting, the liquid material is poured into a mould, and after solidification becomes a solid body. Both too-high and too-low casting temperatures can lead to quality defects. The compact Optris PI 05M infrared thermal imaging camera from Instrotech can monitor the casting process.

Everyone has walked along a wet beach at some time and noticed how the damp sand wobbles like jelly when stepped on several times. This may be fun on a beach, but it’s no joke at a construction site or in an earthquake. Houses and streets built on drained swampland or unconsolidated soil or sediment can sink in certain situations, after which they must be condemned for use.
