The spring constant (N/m) has been measured over a summer to winter temperature cycle to be -245.4 (uN/m)/(N/m)/°C, (-245.4 ppm/°C). The output velocity error with temperature, with Ri at 15K Ohms, is calculated to be (42.3 um/s)/°C/hr. Integrater voltage vs. temperature over the summer to winter time period is 309 mV/°C with a total temperature range of 4.7°C/year. Daily temperature variations are typically 0.5°C or less.
