Extensometer: Types, How It Works, Applications. Geotechnical instrumentation and monitoring is a vast field that includes several monitoring instruments such as piezometers, tiltmeters, strain gauges, beam sensors, extensometers etc. Extensometers or extension-meters are extensively used to measure the change in the length of an object.
Trevor Sparks, George Chase, in Filters and Filtration Handbook (Sixth Edition), 2016. 2.8.2 Stacked disc filters. Stacked disc filters are similar to the edge filter in appearance, in that they have an array of disc-shaped components held on a central core. The stacked disc filters differ however in that the discs are actually hollow, with filter media over the faces of the disc.
