Bailibo high-temperature dielectric measurement system, also known as high-temperature dielectric thermospectrometer, dielectric parameter measurement system, and dielectric tester, is the latest generation of general-purpose, multi-purpose, and multi-functional dielectric performance testing instruments. Main components: host machine (high temperature furnace), measurement fixture, measurement analysis software. The measurement results are truly digitized, and capacitance, inductance, loss, quality factor, etc. are all displayed on the host display. Powerful measurement analysis software can directly measure dielectric constant and loss, impedance spectrum, piezoelectric coupling coefficient, magnetic permeability and other related parameters. Integrated design, simple to use, easy to operate and reliable
-Adopting an integrated integrated design, you only need to simply connect the system to the impedance analyzer or meter measurement wire, turn it on and follow the touch screen program prompts, the operation is intuitive and easy to use.
Unique electrode design, higher repeatability and stability
The principle of parallel plate capacitor is usually used to evaluate the dielectric properties of materials. Using two parallel plates for the upper and lower electrodes is the most ideal situation, but in fact, when making samples During the measurement process, the two planes of the sample and the electrode cannot be in complete contact, and usually only one or more points are in contact. If the conductivity of a certain contact point is poor, it will easily lead to unstable measurement. In order to avoid the above phenomenon, the upper electrode is hemispherical and the lower electrode is flat. This electrode system can accurately position and measure a certain point of the sample being measured, thereby making the system more repeatable and stable.
The self-designed spring electrode system has obtained the national new practical patent
-The high-temperature dielectric temperature spectrum measurement system adopts a spring electrode system, which improves the error caused by the assembly of the fixture and causes poor contact during the measurement process. The phenomenon. The compressibility of the spring allows better contact between the electrode and the sample without damaging the sample, ensuring the stability and reliability of the measurement.
Simulating wire shielding under high temperature conditions can effectively increase the frequency bandwidth of the test and reduce the AC interference of the electric furnace wire
In order to reduce the interference of the AC signal of the electric furnace wire on the wire under high temperature, high-temperature dielectric temperature spectrum measurement The system establishes a high-temperature wire shielding model, which effectively reduces the interference of external signals and increases the test frequency bandwidth. Usually, the impedance analyzer is connected to the measurement electrode using a line-line test method, and the wires connected to the electrode are required to be as clear as possible. The shielding distance is the smallest. Commonly used shielding materials cannot be used in high-temperature environments. Therefore, the electrode leads are covered with high-temperature insulating materials, stainless steel tubes are used as shields for the leads, and stainless steel metal blocks are used to connect the shields of the upper and lower electrodes to form a shield. loop to achieve the purpose of resisting AC interference.
