Surface Temperature Measurements
Used as a surface thermocouple, the Nanmac Self-Renewing Thermocouple will measure the precise temperature of the hot surface without obstructing the flow pattern. The probe can be made of any metal. Thus, matching the properties of the test wall and reducing the thermal conductivity errors to a minimum. As the surface of the wall (if subjected to erosion) wears away; the probe will continuously measure the surface temperature even while the probe itself erodes or wears away (up to 1/2 an inch during this process). This provides an excellent measurement for interface temperatures such as a brake pad to drum interface. Additionally, this attribute allows for shaping of the tip, to fit most any surface contour.
In-Wall Temperature
Used as an in-wall temperature measuring probe, the Nanmac Self-Renewing Thermocouple can be positioned to an accuracy of better than ±0.001 inches. This feature, together with the fast response times of this probe make it an ideal in-wall thermocouple.
Immersion Temperature
Under certain applications the Nanmac Self-Renewing Thermocouple can be used for immersion applications such as within the stream of flowing plastic or high velocity gases. It is however recommended that Nanmac engineers should be consulted for the thermocouple design best suited for immersion.
