Taking Dielectric Measurements to the Liquid State

25.05.2021

The MFIA Impedance Analyzer is connected to a third-party liquid dielectric test fixture

Liquid dielectrics are dielectric materials in a liquid state and are widely used in electrical insulation as well as cooling. Nonetheless, their fluidity also makes accurate dielectric measurements a challenge. In a previous blog post , we saw how to measure solid-state materials with the MFIA Impedance Analyzer and a...

Comparison of Liquid Conductivity Probes

29.04.2021

EIS Probe

In a previous blog post , we described how to use the MFIA Impedance Analyzer to measure the electrochemical impedance spectrum (EIS) of a liquid sample and to derive the conductivity with EIS modeling. The post presented a 5-element equivalent circuit model, which required a relatively deep understanding of electrochemistry...

Voltage and Capacitance in Plotter

Questo articolo illustra come produrre un'onda quadra in tensione ed acquisire i conseguenti transitori di capacità, in una scala temporale molto corta (ad esempio 20 us), per effettuare misure di tipo "deep level transient spectroscopy" (DLTS). DLTS è una tecnica potente e comunemente usata per investigare sia la concentrazione che...

Fast Frequency Sweeps for Impedance Measurements

19.01.2021

Sweeper Trace

When characterizing a device or material as a function of frequency, the resulting spectrum may change with time as the environment or material itself evolves. This time evolution can be captured by taking sequential frequency sweeps with the LabOne Sweeper module on the MFIA or the MFLI. Each sweep requires...

Compensating Cables for Accurate Impedance Measurements

19.01.2021

MFITF attached to MFIA

Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly reduce the accuracy of a measurement. This blog post seeks...

Proximity Sensors – Inductive or Capacitive?

07.01.2021

Proximity Measurement

A proximity sensor is a sensor that detects nearby objects without physical contact [1]. They are commonly used, in applications ranging from production lines to modern mobile devices, mainly thanks to their non-contact configuration and the accompanying long lifetime. The working principle is simple...

Function Generation

Introduction Quite often one wants to generate an electrical waveform to assist his or her lock-in or impedance measurements. Such a function can be generated by a dedicated function generator, but ideally should be produced by the same instrument, not only to save lab space but also to minimize the...

MFIA Dielectrics

A dielectric is traditionally defined as an electrical insulator with very poor conductivity at DC. However, because of its polarizability, charges can be stored in a dielectric material, typically in the format of dipoles, in the low and medium AC frequency range.
