FAQ

  • Why do standard rigid dielectric fixtures produce massive errors in dielectric constant measurements?

    Rigid electrodes cannot perfectly conform to the microscopic surface roughness of solid ceramics, creating a parasitic air gap capacitance that artificially lowers the measured dielectric constant. The MatMeas TSC-6520 utilizes dynamically adjustable, conforming electrode pressure mechanisms that completely eliminate air gaps, ensuring absolute contact and true volume dielectric data.

  • How does the TSC-6520 eliminate the fringing capacitance effect?

    Without proper shielding, the electric field curves outside the edge of the sample (fringing effect), bloating the measured capacitance. The TSC-6520 is engineered with a precision-machined guarded electrode design that forces the electric field lines to remain perfectly parallel through the sample, guaranteeing extreme accuracy across a wide temperature range.

  • What is the primary function of the TSC-6520 test fixture?

    The TSC-6520 is designed to measure the dielectric properties (such as dielectric constant, dielectric loss, and impedance) of solid materials like functional ceramics, polymers, and crystals as a function of temperature and frequency.

  • What is the maximum operating temperature of the TSC-6520?

    The fixture supports a wide operating temperature range from room temperature (RT) up to 600°C or 1000°C depending on the specific configuration and furnace used.

  • How does the TSC-6520 ensure stable contact during temperature changes?

    It features a patented spring-loaded contact design that dynamically adjusts to sample thermal expansion or contraction, ensuring constant contact pressure and preventing data jumps.
