A high sensitivity sensor has been developed recently, suitable for measuring DC and/or middle frequency AC magnetic field. The device has a sensitivity better than 100 pT, it operates in a wide temperature range, it is simple and cheap. Good stability and linearity of the device have been measured. The sensor can be applied for different purposes. High sensitivity and high frequency versions of the sensor are shown in the paper with the most important technical parameters, and some application possibilities in the industry are also indicated. Results, achieved by the sensor in eddy current testing (ECT), are shown more detailed.
