摘要： The present disclosure is directed to a device and a method for forming a precision temperature sensor switch with a Wheatstone bridge configuration of four resistors and a comparator. When the temperature sensor detects a temperature above a threshold, the switch will change states. The four resistors in the Wheatstone bridge have the same resistance, with three of the resistors having a low temperature coefficient of resistance and the fourth resistor having a high temperature coefficient of resistance. As the temperature increases, the resistance of the fourth resistor will change. The change in resistance of the fourth resistor will change a voltage across the bridge. The voltage across the bridge is coupled to the comparator and compares the voltage with the threshold temperature, such that when the threshold temperature is exceeded, the comparator switches the output off.

摘要： One or more embodiments are directed to a resistance bridge having two voltage measurements circuits that function in tandem. In one embodiment, a constant current source may be applied to two resistors coupled in series, in which the first resistor has a known resistance and the second resistor has a resistance to be determined or verified. A first measurement circuit may measure a first voltage across the first resistor and at substantially the same time a second measurement circuit measures a second voltage across the second resistor. The voltage of each resistor is converted to a ratio. Based on the ratio and the resistance of the first resistance, the resistance of the second resistor may be calculated.

摘要： In a method for detecting an offset drift in a resistive Wheatstone measuring bridge, a switch is made between a measuring mode and a testing mode without intervening in the internal structure of the measuring bridge. To this end, in testing mode two sensor resistors which act in the same way and lie in different bridge arms in the measuring mode, are connected in series and a voltage level occurring in the connection of these sensor resistors is compared with a reference voltage. Preferably the sensor resistor which acts in a different way and lies between the two series-connected sensor resistors acting in the same way is bridged. The reference voltage is advantageously formed by resistive division of the voltage applied to the series connection of the sensor resistors. The testing mode may expediently be switched in such a way that the two pairs of sensor resistors respectively acting in the same way are tested in succession.
