Overview:
The right-angle thermocouple is a specially designed temperature sensing device with a 90-degree bent probe structure. It is ideal for installation in restricted or angled spaces where standard straight thermocouples cannot be applied. This design improves accessibility and simplifies routing in complex industrial environments.
Working Principle:
The thermocouple operates based on the Seebeck effect—when two dissimilar metal wires are joined at one end (the sensing junction), a voltage is generated that correlates to the temperature at the measuring point. This voltage is interpreted by a temperature controller or data acquisition system.
Applications:
- Power plants and boiler systems
- Chemical processing pipelines
- Mechanical equipment with space constraints
- HVAC systems
- Food and pharmaceutical machinery
- Petrochemical facilities
