Thermocouples and RTDs

Thermocouples and RTDs (Resistance Temperature Detectors) are types of temperature sensors widely used for temperature measurement in industrial processes, HVAC systems, or scientific research. Thermocouples consist of two dissimilar metal wires, generating a voltage proportional to the temperature difference between the sensing junction and the reference junction. RTDs, on the other hand, are temperature sensors with a defined resistance that changes with temperature. Thermocouples and RTDs offer accuracy, reliability, and compatibility with different temperature ranges and environmental conditions, providing precise temperature measurement in diverse applications.

Pyromation JBA3-F3B072-4-CCLS is a premium spring-adjustable immersion thermocouple designed for flexible, reliable temperature measurement in industrial processes. Its bayonet-style cap on a spring allows the sensor’s insertion depth to be adjusted between ~½″ and 7″, making it ideal when sensor depth may need alteration without full reinstallation. With 6 ft (72 in) fiberglass-insulated leads, a standard plug termination (option 4), cable clamp strain relief (CC), and a long spring (LS), this unit is well suited for versatile installations with wiring safety in harsh environments.

Pyromation The Pyromation R24R-17BH-24-31 is a high-precision Type R (Pt-13%Rh / Pt) thermocouple assembly designed for high-temperature process monitoring. It features an alumina inner protection tube (17BH series) for superior performance in aggressive or high-temperature environments. The 24″ extension length offers deep penetration into process streams or equipment, while the aluminum screw-cover head (code 31) provides robust, secure termination with ingress protection.
