Temperature sensors are essential tools in a wide range of industrial and scientific applications. The LM135AH is an analog temperature sensor, designed to detect both high and low temperatures. It provides an analog output which can be used to determine the precise temperature of a given object or environment. By monitoring the amount of voltage or current passing through the sensor, it can display temperatures ranging from -55 to +150°C with an accuracy of 0.1°C.

The LM135AH consists of two parts, the thermistor and the T terminal. The thermistor is a temperature-dependent resistor which changes the amount of electrical current that passes through it, depending on the temperature. When the temperature increases, the resistance of the thermistor decreases. This causes more current to flow, producing greater voltage from the output. Conversely, when the temperature decreases, the resistance increases and less current passes through, resulting in lower voltage output.

The T terminal is an input, which supplies a voltage or current signal from an external source. The LM135AH then converts the input voltage or current into a temperature measurement. The output thus remains proportional to the temperature, providing an accurate measurement even in harsh or fluctuating conditions.

The analog output can be connected to a data acquisition system or other devices to monitor the temperature. This data can be used for a variety of purposes, such as setting temperature alarms, controlling a cooling system, or locating sources of non-uniform temperature. The output can also be used to trigger other systems, such as an emergency shutdown or activation of a remote alarm.

The LM135AH is a robust and reliable temperature sensor, capable of accurately measuring temperatures between -55 and +150 °C. Its ability to monitor temperature in real-time and provide an analog output makes it an ideal choice for many applications which require precise temperature control. Its small size and low power requirements mean that the LM135AH can be easily integrated into existing systems and can provide accurate readings with minimal maintenance.
