2. Sensing Junction
Insulated Junction
Insulated Junction
Hot junction insulated from sheath. Gives floating output with typical insulation resistance in excess of 100 megohms.
Recommended
Grounded Junction
Grounded Junction
Hot junction welded to sheath tip giving earthed output and faster response to temperature changes
Exposed Junction
Exposed Junction
Fastest response mainly for the measurement of air temperature in ducts. Restricted to a maximum operating temperature of 600ºC

3. Optional Swaged Reduced Tip

A reduced tip is a short section at the end of the sensor sheath that is reduced to a smaller diameter. This can improve response time where faster temperature measurement is required. Select this option if you would like the probe tip reduced.

Frequently Asked Questions

  • What is a thermocouple and how does it work?
    A thermocouple is a type of temperature sensor that generates a voltage when two different metals are joined at one end and exposed to a temperature difference between the "hot" junction (where the temperature is measured) and the "cold" junction (the reference point). This voltage is then measured to determine the temperature at the hot junction.
  • How do I choose the right thermocouple for my application?
    The ideal thermocouple depends on factors such as temperature range, accuracy, termination type, mounting requirements and environmental conditions. We offer a variety of thermocouples with different sheath materials, constructions, terminations, and temperature ratings to meet your needs. If you need specific advice, our engineers are happy to assist!
  • What is the maximum temperature rating of your thermocouples?
    Our thermocouples are designed to handle a wide range of temperatures with some mineral insulated thermocouples able to withstand temperatures up to 1400ºC and ceramic sheathed thermocouples going even higher to 1600ºC. Each product listing includes the maximum temperature rating, so you can choose the best thermocouple for your application.
