DEVICE FOR MEASURING TEMPERATURE Russian patent published in 1995 - IPC

FIELD: measuring temperature. SUBSTANCE: device has temperature transducer having two measuring and two additional wires, resistance-to- voltage converter, amplifier, analog-to-digital converter, information processing unit and monitoring unit. Measuring wires of transducer are connected to input of resistance-to-voltage converter, output of resistance-to-voltage converter is connected to input of amplifier, output of amplifier is connected to input of analog-to-digital converter, which output is connected to information processing unit, which output is connected to monitoring unit. In addition device has circuit for control of temperature transducer, reference gauge, temperature gauges, relay for connecting reference gauge, additional relays, relay for connecting temperature gauges, first and second diodes. This results in possibility to change rate of gauge requests on fly, to select given level and to carry long-duration measurements of temperature at selected level. EFFECT: increased functional capabilities. 2 cl, 3 dwg
