LEEM-16 Dielectric Constant Apparatus

Lintlha tsa Sehlahisoa

Litaba tsa mantlha tsa liteko

1. tekanyo ea tumello ea vacuum e0 le tumello e amanang le eona;

2. ho ithuta LC resonance mokhoa oa ho lekanya capacitance nyenyane;

3. ho ithuta tšebeliso ea oscilloscope ea digital.

Mekhahlelo ea mantlha ea tekheniki

Delengolo	Litlhaloso
Jenereithara ea matšoao ea DDS	Pontšo ea LCD ea 4.3 inch, sine wave le square wave frequency 1μhz ~ 10mhz, amplitude ea signal 0 ~ 10vp-p, waveform signal offset le phase e ka behoa, ho sebelisoa linotlolo tsa digital le coding switch bakeng sa phetoho.
Mohanyetsi ea tloaelehileng	R1 = 1kω, ho nepahala 0.5%.r2 = 30kω, ho nepahala 0.1%
Inductor e tloaelehileng	L=10.5mh, ho nepahala 0.3%
Litlhaloso tsa poleiti ea teko	297 × 300 limilimithara, aperture: Φ4mm, span spacing: 19mm, 50mm le 100mm, joalo-joalo, ho kopana ho hanyetsa ka tlaase ho 5mω, boholo ba hona joale l0a, ajoa capacitance 1.5pf.
