Frequently Asked Questions

A thermocouple is a precision temperature sensor constructed from two dissimilar metal wires joined at a measuring junction that generates a measurable voltage proportional to temperature based on the Seebeck effect. When exposed to temperature differences, thermocouples produce millivolt signals that can be accurately measured and converted to temperature readings across wide temperature ranges with excellent repeatability and stability.
Thermocouples operate on the Seebeck effect principle where two dissimilar metals joined at junctions and exposed to temperature differences generate a measurable electromotive force (EMF). The voltage produced is directly proportional to the temperature difference between the measuring junction and reference junction, enabling precise temperature measurement through voltage-to-temperature conversion.
Common types include Type K (Chromel-Alumel) for general industrial use up to 1260°C, Type J (Iron-Constantan) for moderate temperatures up to 750°C, Type T (Copper-Constantan) for cryogenic and low-temperature applications, Type E for high sensitivity, Type N for high-temperature stability, and noble metal types R, S, and B for ultra-high temperatures up to 1700°C in specialized furnace applications.
Type K thermocouples are most widely used for high-temperature industrial applications up to 1260°C due to excellent oxidation resistance and stability. Type S (Platinum-Rhodium) thermocouples handle temperatures up to 1600°C in inert or oxidizing atmospheres, while Type N provides superior high-temperature stability and drift resistance for demanding continuous operation applications.
Type J thermocouples use iron and constantan alloys, operate up to 750°C, and are ideal for moderate temperature applications with good accuracy in reducing atmospheres. Type K thermocouples utilize chromel and alumel alloys, operate up to 1260°C, and provide superior performance in oxidizing environments making them suitable for high-temperature industrial processes and furnace applications.
Cold junction compensation corrects for temperature variations at the reference junction (typically where thermocouple wires connect to measurement instruments) to ensure accurate temperature readings independent of ambient temperature changes. Modern temperature controllers and transmitters include built-in automatic cold junction compensation using precision reference sensors and advanced algorithms.
Thermocouples are extensively used in industrial furnaces and kilns, heat treatment processes, boiler and steam systems, HVAC equipment, plastic injection molding, chemical and petrochemical processing, food and beverage production, laboratory instrumentation, and research applications where reliable temperature measurement, fast response, and harsh environment capability are essential requirements.
Yes, specialized surface thermocouples with flat-tip designs, spring-loaded contact assemblies, and magnetic mounting systems are engineered for accurate surface temperature measurement on equipment surfaces, pipes, tanks, and machinery providing reliable thermal monitoring without permanent installation requirements.
Standard industrial thermocouples provide accuracy of ±1.1°C or ±0.75% of reading (whichever is greater) conforming to Class 2 specifications. Special limits of error (Class 1) thermocouples offer tighter accuracy of ±0.5°C or ±0.4% of reading for critical applications requiring enhanced measurement precision.
Sheath materials include SS304 for general applications, SS316/316L for corrosive environments, Inconel 600/625 for high-temperature oxidizing conditions, Hastelloy for severe chemical applications, and ceramic tubes for ultra-high temperature measurements selected based on operating temperature, chemical compatibility, and environmental requirements.
Selection depends on operating temperature range, process environment (oxidizing/reducing/inert), required accuracy, response time requirements, mechanical stress conditions, and chemical compatibility. Subhot application engineers provide expert consultation and selection guidance to ensure optimal thermocouple performance and long-term reliability in your specific application.
Subhot manufactures thermocouples in diameters from 1.5mm to 12mm and lengths from 50mm to 3000mm or longer with unlimited custom configurations including bent shapes, coiled designs, and specialized mounting arrangements optimized for specific installation requirements and thermal response characteristics.
Connection options include bare wire terminations, ceramic terminal blocks, miniature and standard thermocouple connectors, threaded process fittings (BSP/NPT), compression fittings, and flanged assemblies enabling seamless integration with existing instrumentation and control systems.
For critical applications, periodic calibration is recommended to maintain measurement accuracy and ensure compliance with quality standards. Subhot provides NIST-traceable calibration certificates, on-site calibration services, and recalibration programs ensuring continued accuracy and regulatory compliance throughout the sensor lifecycle.
Yes, with proper sheath material selection including Inconel, Hastelloy, or specialized ceramic protection, thermocouples operate reliably in corrosive acids, alkalis, and aggressive chemical processes. Additional protection through thermowells or specialized coatings extends operational life in severe chemical environments.
Yes, we manufacture dual-element thermocouples providing measurement redundancy and backup capability, and multi-point assemblies for temperature profiling across multiple zones in furnaces, reactors, and process equipment requiring comprehensive thermal monitoring and control.
Yes, Subhot exports globally with comprehensive international certifications including CE, RoHS, and ATEX compliance providing custom documentation, technical specifications, and application support for international customers, OEMs, and system integrators worldwide.
