Micro-Measurements® has expanded its line of linear and circular diaphragm sensors with the introduction of smaller, higher-resistance patterns to serve a wider variety of pressure measurement applications.
Strain gage manufacturers have produced diaphragm gages for use in pressure transducers for over 40 years. The devices’ unique design allows precise placement of the sensing grids on the diaphragm surface, taking full advantage of the steep strain gradients characteristic to these designs. Built on Advanced Sensors technology, Micro-Measurements’ new generation of diaphragm strain gages offers a number of unique benefits, including improved grid-to-grid temperature matching, a broad selection of patterns, high resistances to 5 kΩ with tight tolerance of ±0.2% per grid, and short grid lengths (down to 0.5 mm). The shorter grids result in a higher output because the active portion of the grid is better matched to the peak strain areas on the diaphragm.
