Experimental apparatus of metal heat bilges cold shrinkExperimental apparatus of metal heat bilges cold shrink ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
In this study, mainly by IC circuit, power switch, power indicator, PVC universal bearing, nylon universal bracket, acrylic rods, metal strips, LED lights, mA sheet music IC buzzer, base composition (as shown above shown).
Power supply, LED lights, milliammeter, music IC buzzer, etc. to form a circuit through the IC circuit, but not the metal strip in contact with one end of the metal sheet, the circuit is in the open state; circuit no current, LED, bee ming, etc. does not work.
When the metal strip thermal expansion (elongation), touch one end of the metal strip sheet metal, the entire circuit is closed, LED, buzzer, etc., mA table shows the size of the current loop.
The device for sound and light way to display expansion and contraction of the metal strip changes.
Overall product specification: 350mm × 260mm × 242mm.
Using a common base of PVC molding, base size: 350mm × 260mm × 70mm; 10mm high legs using special rubber pads to prevent vibration and slipping.
Power input: 12VAC/DC2000mA (universal adapter); push-button power switch with red LED power indicator; Red LED, mA tables, music IC buzzer were fixed at three PVC universal cradle; using the two metal strips acrylic plate fixed on the nylon universal bracket.
