    摘要: A temperature measurement apparatus using a negative temperature coefficient (NTC) thermister is provided. A temperature sensor includes the NTC thermister and a variable resistor part, in which a resistance value of the variable resistor part varies between a first resistance value for a first output voltage value and a second resistance value for a second output voltage value to allow a voltage value corresponding to a present temperature to be outputted. A voltage temperature matching unit outputs the present temperature based on the first output voltage value and the second output voltage value.

    摘要: A thermistor amplifier device comprising a first amplifier and a second amplifier is provided. The first amplifier generates an analog temperature signal output based on a voltage across at least one thermistor. The second amplifier generates an offset voltage input to the first amplifier, wherein the offset voltage is based on maintaining the analog temperature signal within a predefined voltage range. The second amplifier selects the offset voltage corresponding to one of a plurality of range levels, wherein each of the plurality of range levels is associated with a temperature range of the at least one thermistor.

    摘要: The invention relates to measuring the resistance of a resistive sensor, such as a PTC or NTC temperature sensor used for monitoring the temperature of the windings of an electric motor. The invention is based on an electronic circuit in which conductors from a sensor located in the object to be monitored are connected to an amplifier circuit in a feedback configuration that reduces the DC level supplied to the voltage divider when the sensor resistance increases. The measured signal is amplified and, using a comparator to compare it with the output voltage of a sawtooth generator, a continuous PWM (Pulse Width Modulation) signal is generated and transmitted in digital format to a SELV electronic circuit, for example through an opto-isolator. The essentially logarithmic signal amplification makes it possible to reliably distinguish between a short circuit in the sensor circuit and low values of sensor resistance.

    摘要: An object of the present invention is to provide a compact and highly accurate intake air temperature sensor by integrating a fixed resistor, connected in series to a temperature sensing element, into an integrated circuit and dispensing with a reference resistor or a changeover switch for connecting the fixed resistor to this reference resistor. The intake air temperature sensor has a temperature sensing element 2 whose resistance value varies with the intake temperature; an integrated circuit 1 electrically connected to the temperature sensing element 2; a resistive element 3 connected in series to the temperature sensing element 2; a writable memory 7 that stores correction information corresponding to the resistance value of the resistive element 3; and a correction processing unit 6 that corrects errors based on the resistance value of the resistive element 3, which are included in output signals of the temperature sensing element 2, on the basis of the correction information stored in the writable memory 7.
