Abstract

In order to provide accurate and semi-real-time information about performances and conditions of various civil engineering structures thick-film resistors are often being used as strain sensors. For that purpose, Ba2Ru2O7 thick resistive films based on compositions with sheet resistivities of 1 kOhm/sq, 10 kOhm/sq and 100 kOhm/sq were evaluated. Resistors were fired at three different peak temperatures (825oC, 850oC and 875oC) and with three different dwelling times (5 min, 10 min and 15 min) in order to correlate influence of firing variables and thick resistive film strain sensitivity by tracking structure-related changes in resistance, gage factor and noise index values. For 10 kOhm/sq composition values of resistance change vs. temperature and temperature coefficient of resistance were measured and calculated.

Bi2Ru2O7厚阻膜的烧成变量及应变敏感性

为了提供准确和半实时的各种土木工程结构的性能和状况信息，厚膜电阻常被用作应变传感器。为此，评估了基于片状电阻率为1 kOhm/sq, 10 kOhm/sq和100 kOhm/sq的组合物的Ba2Ru2O7厚电阻膜。电阻器在三种不同的峰值温度(825oC, 850oC和875oC)和三种不同的停留时间(5min, 10min和15min)下烧制，通过跟踪电阻、测量因子和噪声指标值的结构相关变化，将烧制变量和厚电阻膜应变灵敏度的影响联系起来。对于10 kOhm/sq，测量并计算了电阻随温度变化的组成值和电阻的温度系数。
