可选的，如图3所示，通孔贯穿箱壁1，通孔的外侧具有凸缘，凸缘的外圈具有外螺纹2，通孔的两端各设有一个带有穿线孔的圆板51、52，箱体外侧的圆板52与通孔处的螺纹螺纹连接，连接线路4从通孔中穿出，两个圆板之间填充有用于对保温箱的内外进行隔热的棉花3。Optionally, as shown in Figure 3, the through hole runs through the box wall 1, the outside of the through hole has a flange, the outer ring of the flange has an external thread 2, and a circle with a threading hole is respectively provided at both ends of the through hole. Plates 51, 52, the circular plate 52 on the outside of the box body is threadedly connected with the thread at the through hole, the connecting line 4 passes through the through hole, and the cotton used to insulate the inside and outside of the incubator is filled between the two circular plates 3.

可选的，仍见图1，还包括伸入所述保温箱中的油管回路，保温箱内的油管回路上设有压力传感器接头，所述油管回路上设有截止阀。该装置专用于压力传感器的校准。由于油路过长，油管中可能存有空气，影响压力传感器的测量准确性，校准前，可以先打开截止阀排除空气，然后再关闭截止阀，对压力传感器进行校准。Optionally, still see FIG. 1 , it also includes an oil pipe circuit extending into the incubator, the oil pipe circuit in the incubator is provided with a pressure sensor connector, and the oil pipe circuit is provided with a shut-off valve.

以压力传感器为例，使用时，将多个待校准压力传感器放入保温箱中，分别连接串口接口和回油管路上的接头，即可开始校准。校准时，通过加热装置或制冷装置将温度调至既定温度，通过外部的油泵向油管回路中加压直至既定压强，然后分别读取该条件下的标准压力以及待校准压力传感器的输出电压，由此计算得到温漂数据和温补数据，将温补数据下发至压力传感器中即可完成该温度下的温度补偿。Taking the pressure sensor as an example, when using it, put multiple pressure sensors to be calibrated into the incubator, connect the serial port interface and the connector on the oil return line respectively, and then start the calibration. When calibrating, adjust the temperature to a predetermined temperature through a heating device or a refrigeration device, pressurize the oil pipe circuit through an external oil pump to a predetermined pressure, and then read the standard pressure under this condition and the output voltage of the pressure sensor to be calibrated respectively, by This calculation obtains temperature drift data and temperature compensation data, and the temperature compensation at this temperature can be completed by sending the temperature compensation data to the pressure sensor.
