Coping with nasty samples and environments

Our current range of Teflon-insulated Hot Disk® sensors for Isotropic, Anisotropic, Slab, One-dimensional and Structural Probe measurements, with operating temperature from -196 °C up to 250 °C, are listed in the following table, followed by photos and detailed dimensions further down:

Sensor model: Radius (mm):
7577 * 2.0
7577 Q */** 2.0
5465 3.2
5465 Q ** 3.2
5501 6.4
5501 Q ** 6.4

* Not for anisotropic measurements.
** For special applications and easier suspension in liquids or melts.

The Teflon-insulated Hot Disk® sensors can be acquired with or without attached cables. Standard cables can be used up to 50 °C, while high-temperature silicone cables are available for temperatures up to 180 °C. Sensors without cable can be mounted in dedicated sensor holders for use up to 250 °C.
