Exhaust gas temperature sensor including strain relief and/or anti-vibration sleeve

摘要

A temperature sensor includes a housing and a temperature sensing element disposed in the housing. Electrical connections may extend from the temperature sensing element through the housing and an epoxy may be disposed in the housing, wherein the epoxy may at least partially around the temperature sensing element. The epoxy may provide a thermal pathway between the sensing element and the housing and may be being flexible to accommodate different rates of thermal expansion between the temperature sensing element and the electrical connections without requiring a separate mechanical strain relief. A temperature sensor system includes a temperature sensor and a mineral insulated cable coupled to the temperature sensor. The temperature sensor may be configured to be removably coupled to the mineral insulated cable via a stop flange and a sleeve coupled to the mineral insulated cable. The sleeve may be configured to provide stability and reduce vibrational stress to the temperature sensor system.
