Description

Technical Field

[0001] The utility model relates to the technical field of batch calibration and detection, in particular to a batch calibration and detection device for temperature and humidity sensors. Background Art

[0002] Temperature and humidity sensors mostly use integrated temperature and humidity probes as temperature measuring elements, collect temperature and humidity signals, and convert them into current signals or voltage signals that are linearly related to temperature and humidity after voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection circuit processing. They can also be directly output through 485 or 232 interfaces through the main control chip. Temperature and humidity sensors are a sensor device equipped with humidity and heat sensitive elements that can be used to measure temperature and humidity. Some have on-site displays, and some do not. Temperature and humidity sensors are widely used in various fields of production and life due to their small size and stable performance.

[0003] However, some temperature and humidity sensors now need to be calibrated and tested before they can be used after they are produced. The existing calibration and testing devices for temperature and humidity sensors have low detection / calibration efficiency, and it is inconvenient to disassemble and assemble the temperature and humidity sensors to be tested when testing / calibrating them, which affects the detection / calibration efficiency. In addition, the detection / calibration process can only be carried out one by one, and batch detection / calibration is not possible, resulting in low work efficiency. Therefore, we propose a batch calibration and testing device for temperature and humidity sensors to solve the above problems. Utility Model Content
