Continuous temperature profiling from a single process connection.
Multi point temperature transmitters combine multiple RTD or thermocouple sensing elements within a single assembly to monitor temperature at several locations simultaneously. The measured values create a complete thermal profile, helping operators detect hot spots, temperature gradients and uneven heat distribution inside process equipment.
The thermo point temperature transmitters range includes rigid and flexible assemblies, thermowell and direct immersion designs, with analogue and digital communication options for integration into modern control systems.
Dutco Tennant LLC is a premium supplier of instrumentation and process measurement solutions across the UAE and GCC, offering a comprehensive range of temperature measurement products for refinery, petrochemical, chemical, power and process industries.
