在农村的栽培、养殖、孵化等实际应用中,经常需要使用恒温控制装置。图1所示电路为恒温值在500℃以内的控制装置。它以 XCT-102型温度指示调节仪作测温和控制部件,固态继电器 SSR 作执行元件。工作前先在 XCT-102的面板上设定所需的恒温值后接通电源开关 S,当感温用的铂热电阻 RT(与XCT-102配套使用,分度号:Pt100)感知的温度低于设定值时,XCT-102的输出端子“中”与“低”接通,SSR 的
In rural areas of cultivation, breeding, hatching and other practical applications, often require the use of thermostatic control device. The circuit shown in Figure 1 is a thermostat at 500 ℃ control device. It is XCT-102 temperature indicator regulator for temperature measurement and control components, solid state relays SSR as the implementation of components. Before working, set the required thermostat value on the panel of XCT-102 and turn on the power switch S. When the temperature of platinum RT RT (used together with XCT-102, index number: Pt100) When it is lower than the set value, XCT-102’s output terminal is “in” and “low” connected to SSR
