PURPOSE:To remove unbalanced state between a transformer on the sensing side and a transformer on the adjusting side, thin the titled sensor and to improve temperature characteristics by arranging a pair of transformers in parallel with a developer. CONSTITUTION:Primary coils 17, 18 and secondary coils 16, 19 are wound around magnetic cores 14, 15 having magnetic gap parts and an adjusting magnetic body 21 for balancing on the developer 10 as a magnetic circuit. Units obtained by winding the coils 18, 19 around a pair of magnetic cores 15 having the size of about 1.0mm. outer diameter X6mm. height by about 50 times are arranged in parallel with the developer, so that the unbalance between the transformers on the sensing and adjusting sides is removed, the device can be thinned and the temperature characteristics can be improved. |
