Abstract

The embodiment of the invention provides an accelerometer comprising a shell, a measurement mechanism, a temperature sensor and a circuit board, wherein an opening is formed in one end of the shell, and the other end of the shell is a closed end; the measurement mechanism is arranged in the shell, and fixedly connected with the shell; the temperature sensor is arranged on one side, far away from the closed end, of the measurement mechanism; the circuit board is arranged on one side, far away from the closed end, of the temperature sensor, and connected with the opening. According to the accelerometer provided by the embodiment of the invention, the temperature sensor is arranged in the accelerometer, the temperature in the accelerometer can be accurately measured, the accurate temperaturecompensation can be provided for acceleration measured by the accelerometer, and the measurement accuracy of the accelerometer can be improved.

Description

technical field [0001] The invention relates to the technical field of acceleration measurement, in particular to an accelerometer. Background technique [0002] The accelerometer is a key component for measuring acceleration in the inertial system. Due to its high measurement accuracy, high reliability and low power, the quartz flexible accelerometer is widely used in inertial navigation, heading attitude, platform stability, and missile steering gear. And drilling control and other systems that require high progress measurement. With the application and development of quartz flexible accelerometers, new requirements are put forward for quartz flexible accelerometers in many fields, not only requiring quartz flexible accelerometers to have higher measurement accuracy and lower power consumption, but also requiring quartz flexible The accelerometer has stronger environmental adaptability and precise temperature compensation. Although a temperature-compensated quartz flexib...
