试验了５１种吸附涂层材料，发现Ｎ，Ｎ，Ｎ，Ｎ－四（２－羟乙基）乙二胺（ＴＨＥＥＤ）涂膜的镀银压电晶体传感器对ＣＯ２具有灵敏响应．当涂膜量为９１μｇ时，传感器的检测范围宽，检测限低至１００×１０－６（Ｖ／Ｖ），且具有可逆性、重现性良好和响应快等优点，变压器油中的其它溶解气体如一氧化碳、氢气、甲烷、乙烷、乙烯、乙炔等干扰小．此外，将该传感器用于模拟变压器油混合气中的ＣＯ２含量的测定，精度尚好
51 kinds of adsorptive coating materials were tested and it was found that the silver-plated piezoelectric crystal sensors of N, N, N, N-tetra (2-hydroxyethyl) ethylenediamine (THEED) coated films are sensitive to CO2. When the amount of coating is 91μg, the detection range of the sensor is wide, the detection limit is as low as 100 × 10-6 (V / V), and it has the advantages of reversibility, good reproducibility and fast response. Other solubilities in transformer oil Gas such as carbon monoxide, hydrogen, methane, ethane, ethylene, acetylene and other interference small. In addition, the sensor is used to simulate the determination of CO2 content in the transformer oil mixture, the accuracy is good
