Solid state sensors are used when fast response times are required, when liquid-in-glass thermometers are not suitable, or when temperatures under vacuum or cryogenic conditions must be measured. The LM27CIM5X-ZHJ/NOPB temperature sensor is an example of a solid state temperature sensor. This sensor offers an accuracy of ± 0.56°C and is capable of measuring temperatures ranging from -55°C to +150°C.

The LM27CIM5X-ZHJ/NOPB is a monolithic integrated circuit that uses a two diode forward-biased thermistor to detect the temperature. It is a three-terminal device, the third terminal being connected to a reference voltage. As the temperature changes, the resistance of the thermistor changes, and this causes the output voltage to vary. This variation of the output voltage is used to determine the temperature.

The LM27CIM5X-ZHJ/NOPB is particularly suitable for applications where temperature stability and accuracy are required, such as cooling systems and environmental control systems. For example, it can be used as a temperature controller to maintain the temperature of a server room or of a process within tight boundaries. It is also used in medical equipment where high accuracy and stability are essential, such as in incubators and refrigerators. Additionally, the sensor provides precise readings in industrial furnaces and boilers for temperature monitoring and control.

The LM27CIM5X-ZHJ/NOPB has a selectable voltage scale range of 0–3V, 0–5V, and 15–20V. It can be mounted directly on heat sinks for efficient thermal coupling. Additionally, it consumes only 1mA of current, which makes it energy efficient. The sensor also comes with a relay output which provides two levels of outputs depending on the temperature. This allows for use as an on/off indicator, and it also makes it useful for controlling fans and other heat management components. Finally, the device is capacitively stable, providing long-term accuracy.

In summary, the LM27CIM5X-ZHJ/NOPB is an accurate and efficient temperature sensor. It is suitable for applications where fast response times, accuracy, and stability are required. Its selectable voltage scale range makes it easy to use, and its relay output makes it useful for controlling fans and other heat management components. Its capacitively stable nature provides long-term accuracy.
