Sensorpia company was established in 2006. The company produce magnetic sensors and magnetic instruments which were developed in Applied Magnetics Laboratory in Hannam University. Main products are flux-gate sensors, blood pulse measuring sensor, terfenol actuator, saturable core tester of on-line tester, and other custom designed precision magnetic measuring instruments. Recently magnetic sensors for satellite were developed and waiting for launching, and drift self-compensating type fluxmeter was developed for nuclear fusion research and now under field test.
