| titleOfInvention | Two-wire transmitter with totalizing counter |
| abstract | Inventors: Peter J. Herzl, a citizen of Canada and resident of Morrisville, Pa., and Robert G. Shaffer, a citizen of the United States of America and resident of New Britain, Pa. ABSTRACT OF DISCLOSURE A two-wire transmitter operating in conjunction with a meter whose output signal varies in frequency as a function of the metered variable. The meter signal is changed into an analog voltage that is converted by the transmitter into a corresponding output current and conveyed to a receiving station over a two-wire line which also supplies operating voltage to the transmitter. In the transmitter, the analog voltage is applied to a differential amplifier which converts the voltage into an output current via a transistor acting as a variable impedance across the line to make up the dif-ference between the operating current drawn by the transmitter and the output current. This make-up current is stored to provide an energy source for operating a totalizing counter coupled to the meter to determine the total amount of the variable passing through the meter. |
