Thermocouples
Thermocouples are rugged, versatile temperature sensors used across industrial, laboratory and commercial applications where accurate and responsive temperature measurement is essential. IOThrifty offers a wide selection of thermocouple probes, beaded wire sensors and accessories designed to support diverse environments, from general-purpose testing to high-temperature industrial processes.
Why Use Thermocouples
Thermocouples measure temperature using two dissimilar metals joined at one end, producing a voltage proportional to temperature. Because they respond quickly, withstand extreme temperatures and maintain durability in harsh environments, thermocouples are standard in manufacturing, process control, research, validation and automation systems. They interface easily with controllers, transmitters, data loggers and panel meters, making them one of the most widely used sensor types in industry.
Types of Thermocouples We Offer
IOThrifty provides a broad range of thermocouple styles and construction options to support a variety of applications.
-
Beaded wire thermocouples, available in custom lengths with stripped leads or miniature/standard connectors. These are flexible, economical and excellent for general testing, temporary setups or locations where quick installation is needed.
-
Fine-gauge thermocouples designed for extremely fast response time. Their small wire diameter allows them to react to temperature changes much faster than standard probes, making them ideal for dynamic testing, airflow measurements, surface temperature studies or any application where speed matters.
-
Surface thermocouples that measure temperature on pipes, plates, heaters or irregular surfaces. These sensors provide accurate contact temperature measurement where immersion is not possible.
-
High-temperature probes built with protective sheaths for furnaces, ovens, kilns and other environments where sensors must withstand elevated temperatures.
-
General-purpose thermocouple probes suitable for immersion, insertion or mounting in tanks, equipment and process lines.
-
Thermocouple extension wire and connectors to ensure proper signal transmission and compatibility with controllers, transmitters and data acquisition systems.
Applications
Thermocouples are used wherever accurate and responsive temperature feedback is essential.
-
Measuring temperature in ovens, furnaces, kilns and heat-treat systems
-
Monitoring liquids, gases and materials in tanks, reactors or pipelines
-
Capturing high-speed temperature events using fine-gauge or exposed-junction sensors
-
Providing feedback to temperature controllers, PLCs and transmitters
-
Logging temperature profiles in testing, R&D and validation environments
-
Supporting HVAC, refrigeration and environmental monitoring systems
Compatibility and Integration
Thermocouples work with a wide range of instrumentation including PID controllers, panel meters, transmitters, DAQ systems and data loggers. Choosing the right thermocouple type (such as Type K, Type J or Type T), sheath material and junction style helps ensure accurate readings, long life and optimal performance. Accessories such as connectors, extension wire and mounting hardware simplify installation and help maintain signal integrity over long distances.
