Multipoint Thermometers

Multipoint Thermometers

Multipoint thermometers are temperature profiling assemblies that place multiple RTD and/or thermocouple sensors along a single mechanical assembly to capture a detailed temperature gradient through a reactor, vessel, or storage system. Rather than a single-point temperature, the output is a profile that supports deeper insight into reaction behavior, stratification, heat transfer performance, or storage thermal stability. Endress+Hauser describes these assemblies as enabling reliable measurement and safe operation in critical applications from low- to high-pressure reactors through storage tanks.

Portfolio architectures include 3D-customizable flexible sensors with or without thermowells (MultiSens Flex), linear arrays with a main thermowell (MultiSens Linear), linear arrays on a rope or in a conduit (MultiSens Bundle), and minimally invasive designs (MultiSens Slim). Options extend to integration with or without temperature transmitters and to diagnostic chamber concepts, and the portfolio includes RTD or TC sensing with Endress+Hauser technologies such as iTHERM ProfileSens referenced in the category description.

The practical benefit is optimized control and improved operating assurance. Temperature profile measurement can be configured as straight or three-dimensional profiling for reactors and vessels, with mechanical and material design aligned for high temperatures, high pressures, and corrosive media. Endress+Hauser also highlights increased safety via a diagnostic chamber intended to contain the process in the event of leakage through primary seals - an important risk-reduction element in critical services.

Typical applications include temperature profiling in hydrocarbon processing and petrochemical duties, process reactor monitoring, and storage condition monitoring in tanks and silos. These assemblies are frequently selected where localized hot spots, catalyst or reaction-zone behavior, or thermal stratification can impact yield, selectivity, or safety. The category explicitly targets coverage of key industries including oil and gas, chemical, food and beverage, and petrochemical operations.

Integration and execution revolve around sensor placement strategy (number of points, spacing, and orientation), mechanical survivability, and signal architecture. Endress+Hauser lists support for common industrial interfaces and protocols in this category’s selection context, including 4–20 mA and multiple digital options, enabling alignment with both legacy and modern distributed control strategies. Properly engineered, multipoint profiling becomes a high-value measurement layer for control optimization and safety monitoring in vessels where a single point is insufficient.
