Abstract
PURPOSE: To reduce temperature drift by cancelling drift dependent upon the temperature coefficient of buoyancy and drift dependent upon the temperature coefficient of springs in respect to oil in the case of the differential transformer system clinometer.
CONSTITUTION: When silicone oil and pure iron are used as damping oil 7 and core 4 respectively, the temperature coefficient of drift dependent upon buoyancy of the core becomes + by specific gravity change accompanied with temperature change of oil and apparent mass fluctuation accompanied with temperature change of core 4. Then, for example, amber is used as a spring material where the sign of the temperature coefficient of the Young's modulus is + for the purpose of selecting - as the sign of the temparture coefficient of drift dependent upon the Young's modulus of springs 5 and 6, so that overall temperature drift can be reduced.
