Temperature

Temperature measurement in process automation includes sensors, thermometers, transmitters, and mechanical protection components that enable accurate sensing under harsh conditions. Endress+Hauser positions a complete assortment including temperature sensors, thermometers, thermowells, process connections, terminal heads, transmitters, measurement inserts, and accessories for process industries. The portfolio spans temperature transmitters, industrial and hygienic thermometers, thermowells, high-temperature designs, compact thermometers, temperature switches, surface thermometers, cable probes, and multipoint thermometers.

Reliable temperature data is foundational for quality, safety, and efficiency, and the category emphasizes seamless integration and long-term performance. Benefits highlighted include international approvals, support for common protocols from analog to digital outputs, reduced operating costs through easier handling and long lifetime, and high productivity through reliable sensor technology and traceable, accredited calibrations. This combination supports consistent deployment across regulated, hazardous, hygienic, and general industrial services.

Measurement-point design begins with how the sensor interacts with the process. Direct immersion typically provides fast, accurate response but can require shutdown for replacement and can increase contamination or wear risk. Thermowells allow sensor exchange without interrupting the process, improving longevity when material and geometry are correctly specified, but they can introduce pressure loss and slower response. Non-invasive surface measurement avoids penetration-related issues such as leakage and wear and is easier to retrofit, while requiring attention to ambient influences and insulation practices.

Sensor and transmitter selection then aligns accuracy, range, and robustness to the duty. RTD and thermocouple sensors are commonly preferred in industrial processes: RTDs for accuracy and long-term stability, thermocouples for wide temperature range and durability. Transmitters convert sensor signals into standardized analog or digital outputs and act as the smart interface to control systems, improving signal stability and enabling diagnostics and consistent configuration across installations.

Typical applications include reactors and columns, heat exchangers, boilers and steam systems, hygienic vessels and transfer lines, and high-temperature equipment where materials, thermowell design, and approvals are critical. Multipoint assemblies support temperature profiling in reactors and large vessels, while surface and clamp-style approaches support retrofit measurement where process intrusion is undesirable. Across these duties, temperature measurement serves both real-time control and formal documentation for quality and compliance.
