Guarded Heat Flow Meter – TCT 716 Lambda - 2

Realizing Precise Determination of Thermal Resistance and Thermal Conductivity Between Classical Heat Flow Meters and Laser Flash Analyzers The TCT 716 Lambda offers the capability of analyzing specimens with optimum dimensions: smaller than conventional HFM and larger than LFA. This enables investigations on homogeneous and inhomogeneous materials with thermal conductivity values ranging from low to medium, for example polymers, composites, glass, ceramics, some metals, etc.

Guarded Heat Flow Meter – TCT 716 Lambda - 4

Realizing Precise Determination of Thermal Resistance and Thermal Conductivity Knowledge about the thermal conductivity and thermal resistance is important in the case of many metals, polymers, and composites because it helps engineers and scientists design and develop materials and products that can withstand high temperatures and thermal stress. Thermal conductivity (λ) is the ability of a material to conduct heat. The thermal transmittance, also known as U-value, is the reciprocal of the total thermal resistance (R, see formulas below). The lower the U-value, the better the insulating...

Guarded Heat Flow Meter – TCT 716 Lambda - 5

With a Guarded Heat Flow Meter, thermal conductivity and thermal resistance can be precisely determined. The heat source and a temperature sensor are surrounded by an active guard (furnace). This prevents lateral heat losses to the environment and increases measurement accuracy. The operator measures the thickness of the test specimen(s), and places them between two heated plates controlled at different temperatures. Temperature sensors (RTD) are mounted just below the plate surfaces for measuring the temperature drop across the specimen. Similar sensors are also embedded in the upper and...

Guarded Heat Flow Meter – TCT 716 Lambda - 6

Instrument Calibration Clamping Control All conditions of calibration, such as management of reference materials, temperature steps and pressure are fully automated with the software. The instrument is calibrated with materials of known thermal resistance. A relationship is established between the known thermal resistance of the calibration material and the related temperature difference and heat flux. For rigid materials, the plates automatically clamp together for optimum sample contact. The user can select from among the following reference materials with predefined thermal conductivity...
