What are the temperature coefficients of tiltmeters?
Temperature coefficients are how we describe the change in output of an instrument that results entirely from a change of instrument temperature. The effects of temperature are primarily 1) thermoelastic (expansion and contraction of the mechanical components), and 2) electronic (aggregate effect of change in properties of electronic components). Applied Geomechanics defines two coefficients to describe the behavior of our tiltmeters as a function of temperature – the temperature coefficient of scale factor change, Ks, and the coefficient of zero shift, Kz. Application of temperature coefficients for correcting (compensating) temperature-induced output changes is described in AGI Report B-95-1005 rev. C .
