The invention discloses a high-precision sensor calibration workbench, which belongs to the technical field of sensor calibration. The base of the calibration platform is set on a marble cornerstone with minimal deformation affected by the ambient temperature, which avoids the influence of the ambient temperature on the base and reduces the environmental impact. The influence of temperature on the calibration accuracy of the sensor, the sensor calibration device adopts multiple sets of bearings to cooperate with each other to realize the rotatable installation on the base of the calibration table, the sensor calibration device can adjust the inclination angle relative to the bottom plate, and the stand is provided with a fixed ear seat A plurality of fixed through holes that cooperate with each other, and then the fixed lugs and the fixed through holes distributed in a circular arc cooperate with each other to realize the fixation of the sensor calibration device at multiple inclination angles. At the same time, a coaxial heat preservation device is arranged outside the sensor calibration device to cooperate It can achieve high-precision, high-speed and high-temperature sensor calibration, and eliminate the influence of the magnetic environment on the sensor calibration accuracy by providing a coaxial heat preservation device with a non-magnetic environment.
Description
technical field [0001] The invention relates to the technical field of sensor calibration, in particular to a high-precision sensor calibration workbench. Background technique [0002] The process of using standard instruments to calibrate the sensor is called calibration. Specifically for piezoelectric pressure sensors, use a dedicated calibration device, such as a piston pressure gauge, to generate a known standard force on the sensor, and the sensor will output a corresponding charge signal. Known standard detection equipment measures the charge signal to obtain the magnitude of the charge signal, and thus obtain a set of input-output relations. Such a series of processes is the calibration process of the piezoelectric pressure sensor. Among them, the three-axis turntable is widely used in the calibration of various direction sensors, and its structural stability and repeat positioning accuracy have a decisive influence on the measurement accuracy of the sensor.
