摘要： An oxygen sensor (1) for detecting the oxygen content of an internal combustion engine exhaust gas system includes a generally cylindrical hollow insulator (3) having a first resistive element (17), preferably of titania, and a second resistive element (19) preferably of zirconia or chromia, adjacent the closed end (9) thereof, grooves (23) adjacent the open end (7) thereof, and an intermediate portion (11) having a shoulder (13), with electrically conductive film leads (29) passing over the surface of the insulator (3) between the resistive elements (17 and 19) and the grooves (23), with a dielectric coating (33) over the conductive film leads (29) in the area of a metal shell (31) to insulate the film leads (29) from the shell (31).

摘要： An oxygen sensor utilizes a chrome oxide compensating resistor (5) in series with a titania sensing resistor (3). The chrome oxide resistor (5) not only compensates for the effects of temperature on the titania sensing (3) resistor, but since it exhibits (p) type behavior while the titania exhibits (n) type behavior in the presence of gaseous oxygen, the sensitivity of the sensor is increased. The resistors (3, 5) can be applied as a film to a substrate (7) or they can be formed as discrete chips. Substantial quantities of alumina and glass can be added to the chrome oxide without affecting oxygen sensitivity although the electrical resistance rises substantially.
摘要翻译：氧传感器利用与二氧化钛感测电阻器（3）串联的氧化铬补偿电阻器（5）。氧化铬电阻器（5）不仅补偿了二氧化钛感测（3）电阻器的温度影响，而且由于它呈现（p）型行为，而二氧化钛在气态氧气存在下表现出（n）型的行为，传感器的灵敏度提高。电阻器（3,5）可以作为薄膜施加到基板（7）上，或者它们可以形成为分立的芯片。可以将大量的氧化铝和玻璃添加到氧化铬中，而不影响氧气的敏感性，尽管电阻显着上升。
