    • A sensor (1) produces the output that changes linearly with absolute temperature. In response to the output, a reference voltage generator (13) produces reference voltages (Vhigh, Vlow) that change linearly with absolute temperature. A Schmidt trigger (14) compares the output signal from a sensor signal amplifier (12) with the reference voltages and produces output. The sensor signal amplifier (12) with a temperature-independent amplification factor amplifies the output signal from the sensor (1) while performing offset compensation. The sensor signal processing circuit (2) is formed of thin-film silicon deposited on an insulating substrate. The output from the sensor (1) undergoes accurate temperature compensation over a wide temperature range, resulting in reliable operation at high temperature.

    • A resistor temperature device (RTD) trip unit is described. The RTD monitors thermal conditions at an industrial process location, such as in a nuclear reactor. Resistance of the RTD varies in accordance with temperature at the monitored process location. An amplifier circuit produces an output signal, corresponding to the variations in RTD resistance, which signal operates a plurality of relay circuits. The relay circuits variously report process conditions such as failure, the obtaining of a preselected leve, etc. Additionally, metering provides a continuous analog indication of thermal conditions at the monitored process locations. To correct for non-linearity inherent in the RTD resistance slope, a recursive feedback path is coupled between the RTD amplifier stage and an RTD current source, such that a decreasing resistance slope produces a complementary increase in current supply to the RTD. The result is a linear output signal from the RTD amplifier.

    • The output of a solid-state temperature sensor is the ratio of a voltage proportional to a reference voltage. The solid-state temperature sensor used diodes in its sensing and reference circuits, however, these diodes exhibit a second order behavior that causes the temperature sensor output response to deviate from an ideal straight line. This output response deviation has a characteristic error curve that is shaped like a parabola. An offset that varies opposite to that of the temperature sensor output response deviation may be determined and applied in the digital domain as offset compensation after the temperature has been conversed to a digital value with an analog-to-digital converter (ADC). By adding this offset compensation to the digital output of the ADC, digital representations of the measured temperatures will track more linearly.
    • 固态温度传感器的输出是与参考电压成正比的电压比。 固态温度传感器在其感测和参考电路中使用二极管,但是这些二极管表现出二阶行为,导致温度传感器输出响应偏离理想的直线。 该输出响应偏差具有形状像抛物线的特征误差曲线。 与温度传感器输出响应偏差相反的偏移可以在数字域中被确定,并且在温度已经用模数转换器(ADC)转换成数字值之后的偏移补偿中被应用。 通过将该偏移补偿添加到ADC的数字输出,测量温度的数字表示将更线性地跟踪。

    • A temperature measurement device comprises a reference voltage source, a three-wire thermal resistor, a voltage drop amplifier, an operational amplifier and compensation resistors R4 and R7. By using connecting wires with resistance values of the compensation resistors R4 and R7, the relation between the output signal ST and resistance of the thermal resistor RT gives rise to a monotonous function, which is independent of the resistances of the connecting wires. After A/D conversion of ST, the value RT and the temperature T can be calculated based on the known functions. Therefore, within the entire measurement range and any length of the cable, the influence of the wire resistances can be fully compensated without the necessity of switches or jumpers.
    • 温度测量装置包括参考电压源,三线热敏电阻,压降放大器,运算放大器和补偿电阻R4和R7。 通过使用具有补偿电阻器R4和R7的电阻值的连接线,输出信号ST与热敏电阻器RT的电阻之间的关系产生单调函数,该函数独立于连接线的电阻。 在ST的A / D转换之后,可以基于已知函数来计算值RT和温度T. 因此,在电缆的整个测量范围和任何长度范围内,可以完全补偿导线电阻的影响,而无需开关或跳线。

    • Electronic circuit arrangement in a temperature measurement circuit based on a platinum resistor (PT) as a temperature sensing resistor, whereby in addition to the platinum resistor there is provided a reference resistor (R1). The measurement circuit (S) is adapted to apply equally large DC currents (I5, I6) to both resistors having a common return lead (3) from these, and to sense the resulting voltage difference (U) across the resistors. By means of at least one operational amplifier (G) the voltage difference is adapted to cause an output DC current from the measurement circuit (S) being proportional to the voltage difference and thereby constituting a measure of the temperature of the platinum resistor (PT). The measurement circuit (S) comprises means for compensating for non-linearity of the temperature-resistance characteristic of the platinum resistor. Two transistors (T1, T2) are provided, of which the collector output currents (I3, I4) are each adapted to be added to its said respective equally large DC current (I6, I5) being applied to the platinum resistor (PT) and the reference resistor (R1) respectively. The emitter-base voltage of the transistors is adapted to vary depending upon the output DC current from the measurement circuit (S).
