Flex TPS (Hot Disc ISO 22007-2) Sensors and Transient Plane Source (TPS) Accessories
Flex TPS Sensors
Trident features hot disc Transient Plane Source (TPS) Kapton and mica based sensors. They measure thermal conductivity at temperatures between -50ºC to 80ºC, with mica sensors testing at up to 500ºC. Sensor sizes range from 6 mm to 30 mm in diameter.
TPS Sample Clamp
Control contact and compression during thermal conductivity measurement of solids with Flex TPS sensors. Ideal for anisotropic, slab, thin films, and homogeneous solid samples.
TPS Powder Testing Cell
C-Therm offers a specialty TPS powder testing cell that allows for consistent control of powder density testing with a 13 mm TPS sensor.
Thermal Conductivity Kit
The C-Therm Thermal Conductivity Kit (TCkit) offers a budget-conscious option for measuring thermal conductivity using the Transient Plane Source (TPS) technique and a double-sided hot disc style sensor. Utilizing a standard Keithley 2401 SMU, the TCkit is an entry-level device for testing up to 60 W/mK. (Note: As it does not contain a bridge circuit, the TCkit does not conform to ISO 22007-2.)

Testing Thermal Conductivity
Easily Test the Thermal Conductivity of Solids, Liquids, Powders, and Pastes
Solids
Polymer Thermal Conductivity Measurement
C-Therm has provided a breakthrough in the characterization of critical performance attributes of conductive polymers used in electronics and automotive industries. The main advantage the technique offers is the flexibility to test a wide range of sample geometries. As an example, clients at a large polymer producer use the test samples from their tensile testing regimen to also test the in-plane and through-plane thermal conductivity with the C-Therm modified transient plane source (MTPS) sensor. Final testing can be completed with ISO conforming TPS hot disc style sensors. There is no longer the need to destructively machine or form specific sample sizes/dimensions to test thermal conductivity.
Powders
From Explosives to Powder Metallurgy
Powders can be tested on both the double sided TPS and single-sided MTPS sensors. Trident is being widely used to safely test the stability, degradation, and shelf life of explosives because it is the only instrument engineered for evaluating the thermal conductivity of powders with a volume as low as 1.25ml (MTPS method). In the growing industry of Additive Manufacturing and Powder Metallurgy, the MTPS method can be used for rapid characterization of samples.
Pastes
Keeping the Hottest Electronics Cool
The faster and smaller microprocessors become, the more heat they generate. C-Therm’s Trident provides vital insights into the development of all materials that contribute to the overall thermal management of devices, including thermal interface materials such as thermal grease and gap pads. These materials are typically compressible, and the thermal conductivity varies with changes in the densification of the material, making consistent compression critical. MTPS offers quick characterization with TPS allowing for final ISO 22007-2 testing.
Liquids
Under Pressure
C-Therm’s Trident thermal conductivity instrument is helping manufacturers improve the heat transfer properties of liquids. C-Therm is unique in offering the capability to accurately measure the thermal conductivity of liquids; the short test time (<1 second) and small sample volume requirements of MTPS negate the convective errors typical in liquid testing with traditional techniques. As an example, clients in the Oil & Gas field use C-Therm’s High Pressure Cell (HPC) accessory in measuring the impact of elevated atmospheric conditions and temperature on the thermal conductivity of drilling fluids.
