为了解决静力触探过程中,由于探头温度变化而引起自动记录仪出现的零飘现象,我们对探头空心柱粘贴电阻丝片的位置及粘合剂种类作了一些初步试验工作,所用试验仪器及线路见图1所示。下面将试验情况及其成果作一简略介绍。首先,我们将四片电阻丝片组成一个桥路,平放粘贴在塑料板上,然后把塑料板从0℃逐渐升温到50℃,供桥电压用6V、8V两挡。试验结果,此两挡输出电压都没有随温度变化而变化,说明温度变形对电阻丝片的影响都是一样的。 In order to solve the static probe process, due to the probe temperature changes caused by the automatic recorder appears zero drift phenomenon, we probe the hollow column paste resistance wire location and adhesive type made some preliminary test work, the use of test equipment And the line shown in Figure 1. The following test cases and their results for a brief introduction. First of all, we will form a bridge of four pieces of resistance wire, flat paste on the plastic plate, and then gradually increase the plastic plate from 0 ℃ to 50 ℃, for the bridge voltage with 6V, 8V two block. Test results, the two-block output voltage does not change with the temperature changes, indicating that the temperature deformation of the resistance of the wire are the same.
