针鳍装置

模型HV-EXP2980
销翅片装置销翅片装置是用来测定从一个延伸表面(销)的热传递。它由一端由电加热器加热的金属鳍片组成。热沿长度&从销钉表面流出。沿引脚长度嵌入5个热电偶测量温度分布，在吸风道内放置1个热电偶测量空气温度。鼓风机通过高速吹空气来提供强制对流。鼓风机流量采用孔板和放大器测量;U形管压力计。控制面板由调光器组成，用于控制提供给加热元件的电压。还提供了电压表、电流表和数字温度指示器。 Specifications: Pin: MOC Aluminium, Pin diameter, 15 mm, Length 20mm Electric Heater: Capacity 200 W, Supply 230 V AC Air Blower: Centrifugal Blower, 230 V AC Orifice Plate: For Air Flow measurement Manometer: U tube manometer, 0-300 mm WC Dimmer: Range 0-250 V AC, 2 A Digital Voltmeter: Range 0-500 V AC Digital Ammeter: Range 0-2 A AC Temperature Sensors: Type ‘K’ Thermocouples – 6Nos Temperature Indicator: 8 Channel Indicator with Selector Switch, Range 0-199.9 ° Frame: Made of M.S.
