Abstract. The article discusses the construction of a single-axis sensitive sensor, which is part of the three-axis seismic detector. The creation problems of a strictly single-axis sensor with additional magnetic stiffness based on the use of SmCo (Samarium-Cobalt) permanent magnets are discussed. A model of a single-axis sensitive sensor is made, the principal original elements of which are elastic extensions and permanent magnets. The elastic extensions hold the test mass of the oscillator, which create mechanical rigidity and simultaneously provide uniaxiality. The permanent magnets add additional “magnetic” stiffness. The creation and testing of the sensor model by the method of tilting the base of the instrument showed that the test results corresponded to the calculated values of the sensor conversion  steepness and its dynamic range.

Keywords: seismometer, mechanical stiffness, magnetic stiffness, mechanical suspension, limiting sensitivity, thermal noise
