1-30 Model
A multizone thermocouple applies to measure temperature of petroleum products in reactors or catalytic converters at an oil refinery. The sensors are placed at different levels. They're made of thermocouple MI cable and spring-loaded inside of directing pipes to ensure firm contact with sheath. Types K or J apply as sensors. This multizone thermocouple can be provided with a thermowell according to customer's drawings.
