FIELD: production process control equipment. SUBSTANCE: temperature controller has thermal resistor, measuring bridge, differential amplifier, output of which is connected to input of voltage-to-frequency converter. Output of supply current source is connected to measuring bridge. Multiplexer inputs are connected to measuring bridge outputs, and its output is connected to differential amplifier input. Power-dependent permanent storage is connected to digital control unit. Output of voltage-to-frequency converter is connected to complementing input of digital control unit. Control lines of digital control unit are connected to multiplexer address inputs. Linearity of output characteristic of temperature controller can be obtained for any type of thermal resistors. EFFECT: enhanced temperature measurement and control. 2 dwg
