A sealed toroidal sensor is formed from two members each including a channel that defines an inner arcuate chamber having a cross-sectional area with a characteristic dimension along a prescribed section of its arcuate length for a given linear angular range and a reduced cross-sectional area along the remaining section of its arcuate length to provide an improved temperature insensitivity. A first electrode is deposited along the prescribed section in the channel of a first of said members and second and third electrodes are deposited along oppositely disposed arcuate lengths of the prescribed section in the channel of the second of said members. After the two members are joined together forming the toroidal housing, an electrolyte is added to the inner chamber which covers relative portions of the electrodes and varies the impedance of the second and third electrodes with respect to the first electrode in accordance with the angular displacement of the device. A novel method of manufacture of the sensor is also disclosed.
