Multipoint sensors are designed for single entry process connection and measure temperature at different points along its length within Catalytic Crackers, Pressurized Reactors, Distillation Columns, Tanks and many other applications. Available in a wide variety of process connections, fixed or remote junction boxes with optional built-in Transmitters, Explosion proof enclosures and other safety items. Flexible versions for coiled shipping or versions with a sturdy protection tube design, using contact leaf springs , bimetal springs or a design with guiding tubes allowing individual sensor replacement during operation. Direct spring loaded sensor to wall contact at the measuring points, or through internal welded heat transfer blocks which ensure the best thermal conductive contact with the inner wall of the protection tube or thermowell. The different systems offer a large number of possibilities to measure the temperatures in the harshest environments and conditions, having a high pressure single or double sensor feedthrough sealing and designs with safety chamber, bleed valve and pressure gauge options.

Quality, Testing and Transportation

Multipoint thermocouples and Pt100 assemblies made by Thermo-Electra meet the highest quality standards. Testing of the sensors and materials include: Dye Penetrant (DPI/LPI), Helium leakage testing, Hydrostatic pressure test (both internal and external), X-Ray examinations (RT), Ultrasonic testing (UT), Positive material identification (PMI), Thermocouple and RTD sensor calibration to IEC/NIST, Electrical insulation test, Third party inspection.
