Sensors (10, 10') for use in sensing the level and temperature of a corrosive medium (14) contained in a container (12). The sensors (10, 10') comprise first and second elongate, conductive sensor members (16a, 16b), each of which has a longitudinal axis and is dimensioned to extend into the medium (14). The first and second sensor members (16a, 16b) each include a core (30, 30') that is made from a non-metallic, electrically resistive material having a plurality of non-metallic conductive fibers (31) embedded therein. Each sensor member (16a, 16b) has opposite ends (22a, 24a, 22b, 24b) and the fibers (31) of the core are oriented parallel to the longitudinal axis of the first and second sensor members (16a, 16b) and extend continuously substantially between the ends (22a, 24a, 22b, 24b) of the sensor members. Medium level can be sensing the capacitance of the sensor members, which changes as the level of the medium changes. By interconnecting the ends (24a, 24b) of the sensor members with a conductive member (50), a sensor is formed that can be used to sense the temperature of the medium.
