Multipoint thermometers are often used for measuring temperature profiles in reactors, fuel depots, or for the detection of “hotspots”.
The so-called multipoint thermometer in band design is a common construction. In this design, several, if required, exchangeable thermocouples or resistance thermometers are linearly arranged on a guide band.
To achieve rapid response times, the individual measuring points are pressed by pressure springs to the internal side of the thermowell which forms a single entity with the thermometer or which can ideally be an already existing component of the reactor. Connection terminals or temperature transmitters are placed in the connection housing which is either a component of the multipoint thermometer or can be mounted separately, e.g. on a wall or pipeline.
