MESSKO变送器Combi Well系列介绍
combi well与thermo well一样，是油温计的装配套管。它可以安装在符合 DIN 42554 的温度计口袋中。但是，它还具有符合 DIN 43760 的集成 Pt100 测量电阻器，因此可以远程传输测量的温度值。combi well由浸入管和连接头组成。评估设备（例如数字显示器）的端子连接以及指针式温度计的温度传感器的浸入管的套管位于连接头中。
The combi well, like the thermo well, is an assembly sleeve for the oil thermometer. It can be installed in the thermometer pocket in accordance with DIN 42554. However, it also has an integrated Pt100 measuring resistor in accordance with DIN 43760 so that the measured temperature value can be transmitted remotely. The combi well consists of the immersion pipe and connection head. The terminal connections for the evaluation devices (e.g. digital display) as well as a bushing for the immersion pipe for the temperature sensor of the pointer thermometer are located in the connection head.
