Magnetic ThermoMeter

Magnetic thermometers measure temperature by utilizing the property that the magnetic susceptibility of paramagnetic salts varies with temperature. The core principle is that the magnetic susceptibility of paramagnetic materials is inversely proportional to temperature under a magnetic field, allowing temperature values to be derived by measuring magnetic susceptibility. They are used for temperature measurement in low-temperature environments, such as laboratories and industrial refrigeration systems.
Selection
When selecting a magnetic thermometer, it is essential to consider whether its temperature measurement range covers the required needs, and to pay attention to how well the characteristics of the paramagnetic salt material match the target temperature zone. Attention should also be given to the relationship between magnetic field strength and measurement accuracy, and to check whether the sensor size is suitable for the installation space. It is important to confirm that the reading method is compatible with the existing system and to evaluate the impact of environmental factors on magnetic susceptibility measurements.
