The electric thermometer circuit composed of LM134

This is an electric thermometer circuit composed of the LM134. In the circuit, the voltage or current output by the LM134 is proportional to the thermodynamic temperature, which can be read on a 100 µA meter. The test temperature range of the meter is from -55°C to 150°C. The power supply can operate even when the voltage is below 1V; however, when precision is required...

The electric thermometer circuit utilizing the LM134 is designed to provide accurate temperature readings across a specified range. The LM134 is a precision current source that converts temperature variations into corresponding output currents. This output is directly proportional to the temperature being measured, allowing for a linear response that is easy to interpret.

The circuit typically includes a temperature sensor, such as a thermistor or a thermocouple, which generates a voltage or current signal based on the ambient temperature. This signal is fed into the LM134, which regulates the output current that corresponds to the sensed temperature. The output current is then directed to a 100 µA analog meter, which displays the temperature in a user-friendly manner.

The operational range of this thermometer is from -55°C to 150°C, making it suitable for a variety of applications, including environmental monitoring and industrial processes. The use of a low-voltage power supply is advantageous, as the circuit can function effectively even when the supply voltage drops below 1V, ensuring reliability in low-power scenarios.

For enhanced precision, additional components such as operational amplifiers or calibration resistors may be integrated into the circuit. These components can help fine-tune the output and compensate for any non-linearities inherent in the temperature sensor or the LM134 itself. Overall, this electric thermometer circuit is a robust solution for accurate temperature measurement in diverse settings.This is the electric thermometer circuit composed of LM134.
