This article describes the LM134-LM10 Thermometer / Temperature Sensor (LM134). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components:LM134.

UsingLM134andLM10integrated circuits, we can build athermometerwhich has -55 to 150°C sensing range.? The ideal meter for this circuit is a 0-200uA digital ampere meter, which can show both positive and negative polarity. This will make the circuit suitable for indicatingtemperaturesbelow 0°C.? LM134 is basically a current source with very accurate and consistent temperature coefficient, so many temperature sensing application find it suitable for the sensor. Here is the schematic diagram of the circuit:
