Abstract
A ceramic sensor device is disclosed which comprises a sensing element of a ceramic material and electric conductors for connection to external circuit which are tightly embedded within a ceramic insulating body. The solid state sensor device having an excellent capability to withstand detrimental conditions such as a high temperature, rapid temperature change and mechanical shocks is provided. The sensor is advantageously used as a temperature sensor, a moisture sensor and a gas sensor for detecting oxidizing and reducing gas. Above all, the sensor is suited as a temperature sensor device for detecting temperature of exhaust gas purifying catalyst used in motor vehicles.
