Field of application
The high modular and robust thermometer finds its use in several applications in almost all industries. An optional head transmitter, with all common communication protocols, makes the device ready to use with enhanced measurement accuracy and reliability compared to directly wired sensors. A variety of process connections, dimensions and materials offer flexible application possibilities.
TEC420 sheathed thermocouples cover temperature ranges from -40°C to 1100°C depending on the type of thermocouple. They can be used in low pressure applications in direct contact with the medium or protected by a thermowell. They can also be used in all applications where small immersion lengths are needed. Special attention should be paid to the maximum operating temperature of the connection head (80 °C if transmitter included).
Benefits
High degree of flexibility thanks to modular design with standard terminal heads as per DIN EN 50446 and customer-specific immersion lengths
High degree of insert compatibility and design as per DIN 43772
Head transmitter with easy selection: Analog output 4 to 20 mA, HART®, PROFIBUS® PA or FOUNDATION Fieldbus™
