MEDIUM TEMPERATURE METER Russian patent published in 2018 - IPC G01K7/01 G01K7/16 

FIELD: physics.

SUBSTANCE: invention relates to information-measuring technology and can be used to convert temperature to voltage. Meter contains at least two thermal converters, an analog multiplexer with a control bus, a stabilizer diode, a DC voltage source, the first and second resistors, an operational amplifier. Thermal converters are interconnected in series. Following equipment is additionally introduced: capacitor, the first and second diodes connected in anti-parallel, the cathode of the second diode is connected to the inverting input of the operational amplifier and through the first resistor is connected to a constant voltage source, and the anode is connected to the common bus and to the non-inverting input of the operational amplifier, the output of which is connected through the second resistor to the input of the first thermal converter. Output of the last thermal converter is connected to the inverting input of the operational amplifier, through a stabilizer diode connected to the second output of the second resistor and through a capacitor to the output of the operational amplifier. Inputs of the analog multiplexer are connected directly or via additional resistors to the input of each thermal converter, respectively, and the output of the analog multiplexer is the output of the device.

EFFECT: broader functional capabilities.
