Abstract
The leakage current in metal oxide varistor bodies is found to vary as a function of applied pressure in the 0.5 kbar to 10 kbar range. A pressure sensing device is conditioned by first prestressing a metal oxide varistor to a pressure above the range of measurement and then releasing the prestress pressure. Upon application of subsequent pressures equal or less than the prestress pressure, the leakage current in the device is found to vary as a function of pressure.
