Description

The magnetic thermocouple is designed as a non-welded option for vessel wall temperature measurement. The circular magnet design incorporates an insulation barrier from radiant heat along with a sensor tip designed to maximise surface contact to ensure accurate temperature measurement.

The neck extension can be manufactured to length based on insulation thickness. The spring-loaded neck extension ensures sensor contact with the vessel wall and allows for maintenance without the use of tools above the insulation/ cladding of the vessel.

Special features

Simplified maintenance and sensor removal without the use of specialised tools
Maximum surface contact tip design
High-temperature applications (up to 540 °C [1,000 °F])
