Type J Thermocouple - 1/8in OD, 18in Probe, 36in Teflon Leads
Type J thermocouples are widely used in industrial and commercial applications for their reliability and versatility. This specific thermocouple is designed for precision temperature measurement while withstanding demanding environments. It features a 1/8-inch outer diameter, an 18-inch long probe, and 36-inch Teflon-insulated lead wires for stable and durable performance.
What is a thermocouple?
Thermocouples are essential devices that measure temperature by converting heat energy into an electrical signal (Electromotive Force, or EMF). They consist of two dissimilar metal wires joined at one end to form a "hot" junction. When the hot junction is exposed to temperature changes, it creates a temperature gradient that generates voltage. This voltage is measured and interpreted as temperature, making thermocouples practical for real-time monitoring and control in industrial processes. Type J thermocouples, in particular, are made from iron and constantan metals, offering excellent performance within moderate temperature ranges.
Key Features of This Thermocouple:
- Probe Specifications: Ungrounded junction for fast response time and lower electrical interference, 1/8-inch outer diameter, 18-inch probe length for versatile placement.
- Lead Wires: 36-inch Teflon-insulated lead wires. Teflon insulation provides excellent resistance to chemicals, abrasion, and high temperatures, ensuring reliability in rugged environments.
- Temperature Range: The probe operates between 0 °C to 760 °C (32 °F to 1400 °F), making it ideal for a variety of industrial applications. The lead wires have a maximum ambient temperature limit of 204 °C (399 °F) for continuous use.
- Durable Design: Includes a standard transition with spring support to protect the lead wires from strain or breakage during operation.
- Wire Color Code: Red and white wires for easy identification and installation.
Applications:
Type J thermocouples are commonly used in processes like heat treating, plastic molding, ovens, furnaces, and other general-purpose temperature measurement applications. Their moderate temperature range and durability make them suitable for industries including manufacturing, HVAC, food processing, and laboratory testing.
