This article presents results of a research on an optical fiber current sensor with external conversion (OFCS-EC). Presented OFCS-EC works on the principle of the Faraday effect. The active element in a sensor head was made of the reliable glass characterized by a high Verdet constant. The sensor was investigated in alternating magnetic field. The sensor was investigated in a configuration known as the optical fiber current transducer (OFCT). In this configuration an electric conductor was a source of a magnetic field. The variations of a output signal is a result of the Faraday effect in the sensor head. Investigations presented in this paper are focusing on checking whether a response signal from the OFCS-EC registered in condition closed to an industrial environment. The results of these investigations have proven very good stability and linearity of the output OFCS-EC signal.
