Description
Technical field
The present invention relates to a kind of calibrating installation, a kind of meteorology Fibre Optical Sensor temperature calibration instrument that can seal.
Background technology
The certainty of measurement of temperature sensors of high precision is affected, in order to reach the accuracy Design requirement of chip by manufacturing the many factors such as process deviation, encapsulation stress, it is necessary to calibrate the temperature sensor chip after Preliminary screening, encapsulation.
The structure of existing temperature sensor calibration system, including temperature calibration system, thermometric instruments；Temperature calibration system is for gathering the measurement data of chip to be calibrated, and thermometric instruments is for gathering the operating ambient temperature data of chip to be calibrated.
The major defect of this structure is:
(1) thermometric instruments must be high-precision, and cost is high.
(2), in calibration process, the temperature probe of thermometric instruments is difficult to combine well with chip to be calibrated and temperature environment as having.
(3) requiring that chip to be calibrated and test probe are immersed in liquid environment, building of this calibration environment is more complicated, and owing to needs change calibration temperature to liquid heating, prover time is longer.
The Chinese invention patent application of Application No. 200810044099.X disclosed in 23 days June in 2010, entitled " the calibration system of temperature sensor chip and the calibration steps " of its innovation and creation, it includes test board, temperature calibration system；Temperature sensor reference chip and chip to be calibrated it is provided with on test board；Each chip is connected communication by unified digital interface with temperature calibration system.The temperature calibration system of the present invention, reads each chip to be calibrated and the temperature value of reference chip by unified digital interface；Each chip to be calibrated gathers data simultaneously, it is achieved that multi-chip data collection synchronous is calibrated, it is possible to be greatly improved the collecting efficiency of data, reduces the detection calibration time of chip, reduces calibration cost.Have simple in construction, easily build, prover time is short, calibration efficiency is high, low cost and automaticity advantages of higher.
