TEMPERATURE CONVERTER Russian patent published in 2003 - IPC

FIELD: measurement technology, devices measuring temperature with its direct conversion to frequency of electric signal. SUBSTANCE: temperature converter includes generator with frequency-setting network which incorporates temperature-sensitive resistor and several resistors connected in series, switch changing connection of frequency-setting network, device controlling switch coming in the form of first counter and second modulo three counter. Input of first counter is connected to output of converter and outputs of modulo three counter are connected to controlling inputs of switch. EFFECT: simplified circuit of converter, potential for automatic switching of measurement channels. 2 dwg
