PXF5ACY2-FW100说明书PXF5ACY2-FW100富士温控器顾名思义，温度控制器是一种用来控制温度而无需操作人员的大量参与的仪器。

温度控制系统的控制器从热电偶或RTD等温度传感器接收输入信号后，将实际温度与所需控制温度或设定值进行比较。

然后将输出信号提供给控制元件。

例如，控制器从温度传感器接收输入信号，并将输出信号发送至所连接的加热器或风扇等控制元件。

控制器通常只是整个温度控制系统的一部分，因此在选择适当的控制器时，应对整个系统进行分析和考量。

温控器（Thermostat），根据工作环境的温度变化，在开关内部发生物理形变，从而产生某些特殊效应，产生导通或者断开动作的一系列自动控制元件，或者电子原件在不同温度下，工作状态的不同原理来给电路提供温度数据，以供电路采集温度数据。

流体媒介温度控制器是利用感温流体热胀冷缩及液体不可压缩的原理而实现自动调节。

当控制温度升高时感温液体膨胀产生的推力将热媒关小，以降低输出温度；当控制温度降低时感温液体收缩，在复位装置的作用下将热媒开大，以提高输出温度，从而使被控制的温度达到和保持在所设定的温度范围内。

双金属片温控器工作原理根据物体热胀冷缩原理。

热胀冷缩是物体的共性，但不同物体其热胀冷缩的程度不一样。

双金片的两面是不同物质的导体，在变化的温度下由于胀缩程度不一样而使双金片弯曲，碰到设定的触点或开关，使设定的电路（保护）开始工作。

色温型温控器，工作原理系采用一些涂料在不同的温度下会产生不同的色彩的原理。

比如用液晶在不同温度下，就可以产生不同的颜色，再用摄像头类的色彩采集器以给电路提供不同的数据，从而对电路进行控制。
