TPS Sensors
TPS sensors are available in both a two-sided and single-sided design. There is also a variety of sensors available for different material types, geometries, and measurement temperatures. All TPS sensors can be used to measure homogeneous, heterogeneous, isotropic and anisotropic materials.
Key Advantages
• Homogeneous and heterogeneous
• Isotropic and anisotropic
• Solids, liquids, pastes, and powders
• No thermal contact agent required
• Two-sided and single-sided
• Direct measurement, no complex calibration required
Two-Sided Sensor
The two-sided TPS sensor offers the best accuracy, repeatability, temperature range as well as sample size flexibility.
Temp: -160 to 1000°C (Mica and Kapton Insulation)
Accuracy: better than 5%
Repeatability: better than 1%
Thermal Conductivity: 0.001 to 1800 W/mK
Additional properties: Thermal Diffusivity & Specific Heat
Minimum sample: 2 mm diameter / square
No max on thickness or diameter / square

Single-Sided Sensor
The single-sided sensor offers excellent accuracy and repeatability without the requirement of two pieces of sample. This is a very convenient sensor for testing large hard to handle samples.
Temp: -160 to 300°C
Accuracy: 5%
Repeatability: better than 2%
Thermal Conductivity: 0.01 to 1800 W/mK
Additional properties: Thermal Diffusivity & Specific Heat
Minimum sample: 6, 15 or 30 mm diameter / square
No max on thickness or diameter / square
