Type J Thermocouple with 1/8" Outer Diameter, 12" Probe, and 36" Teflon Leads
Product Overview This Type J Thermocouple is a precision-engineered sensor designed for accurate and reliable temperature measurement. Featuring a robust 1/8-inch outer diameter and a 12-inch probe length, it is versatile enough for various applications. The 36-inch Teflon-insulated leads provide excellent resistance to chemicals, moisture, and abrasion, ensuring signal integrity even in challenging environments.
What is a Thermocouple? Thermocouples are among the most versatile and widely used temperature-sensing devices in industrial, commercial, and scientific settings. They operate on a simple principle: when two different types of metals are joined at one end (the "hot" junction), a small, predictable voltage, or Electromotive Force (EMF), is generated when that junction is heated or cooled. This voltage changes in proportion to the temperature, allowing for precise measurement. This signal is then read by a controller or recorder and converted into a standard temperature unit (like Celsius or Fahrenheit).
Key Features of the Type J Thermocouple:
- Composition: Type J thermocouples are made from a junction of Iron and Constantan (a copper-nickel alloy).
- Temperature Range: They are highly effective for measuring temperatures from approximately -40°C to 750°C (-40°F to 1382°F). Their accuracy and stability make them a popular choice for mid-range temperature applications.
- Applications: Ideal for use in plastics and rubber manufacturing, heat treating, and various industrial processes where monitoring and control are critical.
- Cost-Effective: Type J thermocouples offer a great balance of performance and affordability compared to other types.
