Abstract

A temperature transducer includes first and second resistor bridges connected across a voltage source and first and second differential amplifiers. A first input terminal of the amplifiers are connected together to a common junction of the first resistor bridge. The second input terminals are connected to the second resistor bridge, one directly and the other via a voltage divider so that the input voltages of the differential amplifiers are mutually shifted to obtain two different operating voltage thresholds.
