Magnetic Surface Thermocouple

Magnetic surface thermocouples are fixed to metal surfaces using magnetic attraction, directly measuring the surface temperature of objects through the thermoelectric effect. Their principle relies on the generation of a thermoelectric electromotive force at the contact point between two different metal conductors, which is transmitted via wires to an instrument for temperature display. They are suitable for monitoring the surface temperature of magnetic metal equipment such as boilers and pipelines, enabling quick installation and use in industrial settings.
Selection
When selecting, consider that the temperature measurement range should cover the temperature of the object being measured, and the magnetic force should adapt to the surface curvature and cleanliness. Confirm the magnetic permeability based on the metal material, and choose an armored or flexible structure in combination with environmental vibration. Match the interface type of the existing instrument, and select corrosion-resistant materials in corrosive environments. The installation space determines the probe size and wire length.
