Overview

Micro-Thermocouple Design

  • Flexible, Ultra-Thin Tip Options and Design: Low thermal mass for minimal influence on object temperature
  • Superior Accuracy: Inudstry leading accuracy for maximum performance in even the most complex environments
  • Fast Time Response: Suitable for applications where temperature changes need to be detected quickly
  • Scalable, Advanced Manufacturing: TE Connectivity processes allow for unique offerings and advanced capabilities

Micro-Thermocouples (MTC)

Did You Know?

  • The time response of MTCs are fractions of a second, making them suitable for applications where rapid temperature changes need to be detected.
  • Type-T thermocouple wire is non-magnetic, so it can be used in magnetic applications without complications.
  • Special Limits of Error defines the interchangeability of the thermocouple; which is the greater of 0.5°C or 0.4% for type T.
  • Welded joints provide additional options for thermocouple wire types versus solder joints.
  • For MTCs to provide accurate measurements, alloy wire must be used to connect a thermocouple sensor to the temperature sensing instrumentation.
  • Polyesterimide is the preferred insulation material for Type-T thermocouple wire, because it bonds well to both legs of the thermocouple and is mechanically robust.
  • The time response of a thermocouple is dependent upon the medium of submersion, the wire diameter, the alloy type and the applications temperature. Encapsulating the thermocouple junction will slow the time response slightly.
  • TE’s innovative polymer encapsulation technology is made from a bio-compatible polymer, and is available standard and in custom lengths and thicknesses.
  • The maximum temperature rating for polyesterimide insulation is 180°C.
  • The maximum temperature rating for polyimide insulation 240°C.
  • Micro-tube thermocouples can be supplied in a wide variety of medical grade stainless steel housings.

Featured Applications

Application Feature Benefit
Ablation Therapy Micro-thermocouples monitor the temperature, duration, and spread of heat to the surrounding tissue Allows the tumor to be ablated while protecting nearby tissue
The MTC provides the smallest profile, most precise geometry, and easiest assembly for the medical device manufacturer Provides the best performance and control for the surgeon while keeping manufacturing costs down
Tissue Shrinkage Very small size, AWG#36 to AWG#44. Can be used for the treatment of varicose veins An RF catheter is snaked into the vein and the vessel is heated with RF energy as the catheter is withdrawn, causing the vein to collapse
Fast response time and accurate temperature feedback The high flexibility and very small diameter of the micro-thermocouple allows for treatment on very small vessels
Microelectronincs Small size and low profile Fits into tight spaces and under thermal-producing components
Rugged construction: Protects the sensing element and provides years of reliable operation Suitable for a wide range of industrial applications
Mechanical Devices (Bearings) Industry standard materials – type K and type T Allows for the use of standard interface products and designs
Available in welded or soldered junctions Capability to detect very small acoustic signal levels
