<p>An arcuate resistive sensor element is imprinted upon a ceramic substrate (13) forming a wall of a ceramic body in which an electrolyte (12), advantageously silver nitrate dissolved in a mixture of methanol, water and butanol, is sealed. To avoid the effects of electroplating, an AC exciting voltage is applied between the ends of the sensor element which is bridged by a discharge resistor (30) whose resistance is much lower than the internal resistance of the sensor element so as to dissipate any polarization caused by asymmetry of the voltage supply. A signal output is taken from a midpoint of the sensor element (19) which is always immersed in the electrolyte so that the effect of any leakage current is minimized. Linearity of output with change in the tilt angle achieved with an illustrative embodiment has been measured at better than 99.9 % in tilt angle range of -50 to +50 degrees.</p> |
