ABSTRACT:
An accurate level sensor having an electrolytic switch 10 is mounted within a chamber 22 on a thermally insulating member 12 and is surrounded by a thermally insulating air space 23. Chamber 22 is mounted within a chamber 24 by thermally insulating members 38 and is surrounded by a thermally insulating air space 25. Chamber 24 is mounted to an inertial reference member 44 by thermally insulating members 46. All mounting surfaces are precisely parallel to each other and sensitivity to ambient temperature conditions is attenuated to provide a sensor for maintaining the inertial reference member level and stable within a high degree of accuracy.
