IPC: G01P15/08
Filed: 1994-01-20
Abstract: PURPOSE:To accurately detect the direction and absolute value of working acceleration by detecting temperature change with the movement of a gas having a temperature distribution when acceleration works against a case. CONSTITUTION:The heat generated from a heat generating body 4 is transmitted by a gas 6 it forms a temperature distribution corresponding to the distance from the body 4. In addition, a temperature distribution with a large temperature gradient is formed by adopting a pressurized gas with a low heat conductivity as the gas 6. Then, a temperature sensing means 5 for detecting acceleration is placed at a specified distance from the body 4 in a working direction of acceleration G. Thus, the means 5 is arranged and the pressurized gas with a low heat conductivity such as nitrogen gas or argon gas, etc., is used to make the temperature gradient larger, thereby making it possible to detect much lower temperatures than the heat generating temperature of the body 4. Therefore, temperature changes due to changes in acceleration G can be detected accurately.
