Pressure sensor debugging system and debugging method thereof

Abstract

The invention provides a pressure sensor debugging system and a debugging method thereof. The pressure sensor debugging system comprises a multipath sensor testing pressure seat, a high-low temperature chamber, a pressure controller, a multipath signal switching module, a programmable power supply, a high-precision multimeter, a uniline digital conversion module and an industrial personal computer. The system can realize high-precision pressure calibration and temperature compensation; the work temperature range of the compensated product is wide; the whole debugging process is finished by the system automatically; and the system is suitable for the pressure sensor in volume production to debug.

Description

technical field [0001] The invention relates to special equipment for sensor production, in particular to a pressure sensor debugging system and a debugging method thereof. Background technique [0002] At present, most domestic sensor manufacturers use evaluation kits or single-chip microcomputer systems, and use MAX1452 chips to make samples or small batches of products. The debugging process is complicated and requires manual debugging of each product, from observing the output of the sensor to changing the internal data, and then observing. Change again until the output meets the requirements, then increase the pressure to the full scale, and then change the internal data to debug the full scale. When returning to the zero point again, the zero point will usually change due to the range adjustment, and cannot form a data closed-loop automatic adjustment and channel automatic adjustment. Switching, and the debugging of sensors for batches takes longer, so the entire debug...

Problems solved by technology

[0002] At present, most domestic sensor manufacturers use evaluation kits or single-chip microcomputer systems, and use MAX1452 chips to make samples or small batches of products. The debugging process is complicated, and each product needs to be manually debugged in sequence, from observing the output of the sensor to changing the internal data, and then observing. Change again until the output meets the requirements, then increase the pressure to the full scale, and then change the internal data to debug the full scale. When returning to the zero point again, the zero point will usually change due to the range adjustment, and cannot form a data closed-loop automatic adjustment and channel automatic adjustment. Switching, while debugging for batch sensors takes longer, so the entire debugging process needs to be repeated, which is inefficient
