Multi-Point Thermocouple

Multiple thermocouples are used from a single point and every thermocouple to be place at different level of rectors, to measure accurate profile of reactor. Each measuring points are stuffed or drawn into an outer protection tube. The measuring points are placed at various levels to suit the application. Depending on customer needs, the protection tube is then assembled with a process connection for direct mounting or inside a guide tube. Connection terminals or temperature transmitters are placed in the connection housing which is either a component of the multipoint thermocouple or can be mounted separately, e.g. on a wall or pipeline.

These assemblies are used when a temperature profile is desired and mass, or size, of the sensor is a limitation. They can be constructed in a wide variety of configurations to suit the specific application
