Abstract
A transmitting system including an admittance sensing probe having sensing elements adapted to sense both the composition and the level of materials. The probe is coupled to admittance responsive networks forming part of a common oscillator which generate admittance signals representing the level and composition of the material. A remotely located power supply provides current to the transmitters through two pairs of lines, and the output currents of the transmitters represent the level and composition of the materials.
