GEOMAGNETISM SENSOR INCLUDING PHASE CHANGE MATERIAL

摘要

The present invention relates to a geomagnetic sensor comprising a powder formed phase transition material; and a constant-temperature layer coated on the sensor surface. More specifically, a phase transition material of the present invention maintains temperature of the sensor to be constant wherein the size of the phase transition material is 0.1-100um. In addition, the constant-temperature layer is made of epoxy.
