Ceramic type sensor device.

摘要

A ceramic sensor device is disclosed which comprises a sensing element of a ceramic material (11, 12) and electric conductors (13) 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.
